Build Your AI English Coach

Use Google Gemini prompts to build a personal AI English tutor.

Introduction

30 Second Summary

Imagine having a patient English tutor who is available any time you want to practice, never judges your mistakes, and always explains exactly what you got wrong and why. That kind of help usually costs serious money.

In this project, you will build a personal AI English coaching system inside Google Gemini that corrects every mistake you make, explains the grammar rule behind it, and teaches you new vocabulary based on topics you actually care about.

What You'll Build

You open Gemini, paste your coaching prompt, and start chatting about your day. The AI responds naturally, then adds a corrections section showing exactly what you said wrong, why it was wrong, and new words to remember.

By the end of this project, you'll have:

A personal English coach that catches every grammar and vocabulary mistake in your messages, with corrections and explanations tailored to your level.
A collection of ready-to-use prompts for different practice modes: free conversation, writing correction, grammar drills, vocabulary building, and roleplay scenarios like job interviews or gaming chat.
A weekly practice routine that builds your English from A2-B1 toward B2 level using free AI tools, 15 minutes a day.
Secret Mission: Build a "Level Up" quiz system that tests you on everything you learned and tracks your progress week by week.

Are there any prerequisites?

You need a Google account (for free access to Gemini) and the ability to read simple English sentences. No coding, no installation, and no payment required.

Before We Start

Before We Start...

Before we dive in, let's lock in what you're about to build and why it matters to you.

Set Up Your English Practice Space

Before you build your AI English coach, you need a workspace where you can practice. Gemini is a free AI chatbot by Google that runs directly in your browser.

In this step, you'll open Gemini, start a fresh conversation, and send your very first English message to see how the AI responds without any special instructions.

In this step, get ready to:

Open Google Gemini in your browser.
Sign in with your Google account and start a new chat.
Send your first English introduction message and see a response.

Open Google Gemini in your browser

Gemini lives on a website, so you just need your browser to get started.

Open your browser (Chrome, Edge, Firefox, or Safari).
Type gemini.google.com into the address bar and press Enter.

You should see the Gemini homepage with a text input area where you can type messages.

Page not loading?

Make sure you typed the URL exactly as gemini.google.com with no extra spaces or letters.

Check your internet connection by opening another website. If other sites work but Gemini does not, try a different browser.

Why can't I access Gemini?

Sign in and start a new chat

Gemini requires a Google account so it knows who you are and can save your conversations for the session.

If Gemini asks you to sign in, click Sign in and enter your Google account email and password.
Once signed in, look for a New chat option in the sidebar or at the top of the page. Click it to start a fresh conversation.

You should now see an empty chat with a text input field at the bottom, ready for your first message.

Why start a new chat?

A new chat gives you a clean slate with no previous context. This is important because later you will compare how Gemini responds with and without coaching instructions.

Send your first English message

Time to type your first message in English. You are going to introduce yourself so Gemini has something to respond to.

Click in the text input field at the bottom of the chat.
Type a short introduction about yourself in English. Include your name, your age, and 2-3 hobbies you enjoy.

Not sure what to write?

Try something like: "Hello, my name is [your name]. I am [age] years old. I like basketball, gaming, and football." Write whatever feels natural. It does not need to be perfect.

Before you send your message, take a guess. What do you think Gemini will do with your introduction? Will it just say hello back, or will it do something more?

Press Enter or click the send button to submit your message.

Gemini responds in English. It likely greets you, comments on your hobbies, and asks a follow-up question. You have just had your first English exchange with AI.

Gemini responding in a different language?

If Gemini replied in Estonian or another language, send a follow-up message: "Please respond to me in English." Gemini matches the language you write in, so always type your messages in English.

How do I make Gemini always respond in English?

Your practice space is ready and Gemini is chatting with you in English. Next up, you'll have a longer conversation and discover something surprising about how Gemini handles your mistakes.

Have Your First English Conversation

You've introduced yourself to Gemini and it responded back in English. Your practice space is working.

Now it's time to put it to the real test. You're going to have a full conversation about your hobbies and see how Gemini handles your English.

In this step, get ready to:

Chat about your hobbies in English for 3-4 messages.
Test whether Gemini notices mistakes in your English.

Chat about your hobbies in English

You already said hello to Gemini. Now write about something you actually enjoy. Don't worry about being perfect.

In your existing Gemini chat, write a message about one of your hobbies: basketball, football, or gaming.
Write naturally without checking your grammar. Use the English you know, even if you're not sure it's correct.
Send 3-4 messages total. Tell Gemini what games you play, which team you support, or what sport you played this week.

Example topics to write about

Try writing about things like: "Yesterday I play basketball with my friends" or "I am liking Nintendo Switch very much" or "Football is more better than basketball." These kinds of natural mistakes are exactly what a teacher would normally catch.

After sending your 3-4 messages, scroll back through the conversation and read Gemini's responses.

Look at what Gemini said back. Did it point out any grammar mistakes? Did it suggest a better way to say something?

Ask Gemini to check your English

You've sent several messages now. Some of them probably had mistakes in verb tenses, prepositions, or spelling. Before you ask Gemini directly, think about this: what do you expect it to say?

Think for a moment: if you ask Gemini whether your English was perfect, do you think it will give you a list of specific corrections?
Type this message into Gemini and send it:

Was my English perfect in this conversation?

Read Gemini's response carefully. It either says your English was good, gives a generic compliment, or offers only vague suggestions with no specific corrections tied to your actual messages.

Why didn't Gemini correct me?

Without explicit correction instructions, AI prioritizes conversational flow over error correction. Gemini is designed to be a helpful, polite chat partner. It keeps the conversation going smoothly instead of stopping to teach you.

This is the core problem. Chatting with AI without instructions feels easy but teaches you nothing. You need a way to transform Gemini from a polite friend into a strict-but-friendly teacher.

Gemini actually corrected some mistakes?

Occasionally Gemini may point out one error if it made your message hard to understand. But notice: it does not catch every mistake, does not explain grammar rules, and does not teach you vocabulary. That inconsistency is the problem. A real teacher would catch everything, every time.

help me understand why Gemini sometimes corrects and sometimes doesn't

Now you've seen the gap firsthand. Gemini is happy to chat, but it will not teach you unless you tell it to. In the next step, you'll build a coaching prompt that transforms Gemini into a real English teacher.

Build Your English Coach Prompt

In Step 2, you discovered the core problem: Gemini happily chats with you but never corrects your mistakes. That makes it a conversation partner, not a teacher.

A structured coaching prompt changes everything. By giving Gemini specific rules about your level, your native language, and how to format corrections, you transform it into a patient teacher that catches every error and explains the grammar rule behind it. This is what makes free AI worth more than expensive language apps.

In this step, get ready to:

Paste the English Coach prompt into a new Gemini chat.
Write a coached message and see corrections for the first time.
Test the PAUSE and RESUME commands for switching languages.

Paste the English Coach prompt into a new chat

The key to prompt engineering is telling the AI exactly what role to play, what rules to follow, and how to format its responses. Your coaching prompt does all three.

In Gemini, click the + New chat button in the top left to start a fresh conversation.

Copy the entire prompt below and paste it into the Gemini message box, then press Enter to send it:

You are my personal English coach. Here is my profile:

- Current level: A2-B1 (pre-intermediate)
- Native language: Estonian
- Goals: Use English for college, workplace, and gaming
- Topics I enjoy: basketball, football (soccer), video games (Nintendo Switch), technology
- Preferred English: American English

Rules for every message I send:

1. Respond to my message naturally in English, at a level slightly above mine (use B1 vocabulary with occasional B2 words).

2. After your response, add a clearly separated section with:
   - CORRECTIONS: Fix any grammar, vocabulary, or spelling errors. Show wrong vs correct side by side.
   - EXPLANATION: Briefly explain why each correction is needed (the grammar rule) in simple English.
   - VOCABULARY: Highlight 1-2 new words from your response with pronunciation guide, definition, and one example sentence.

3. Every 5 messages, do a mini-review:
   - List all new vocabulary from the last 5 exchanges
   - Quiz me on 2 words from earlier in our conversation
   - Suggest one grammar pattern to focus on based on my mistakes

4. Keep your responses short and conversational. Do not write essays. Ask me one follow-up question at the end to keep the conversation going.

5. If I write PAUSE, switch to Estonian and let me ask any grammar question in Estonian. Explain the answer in Estonian. When I write RESUME, switch back to English practice.

6. If I write SCENARIO followed by a description, start a roleplay based on that scenario. Stay in character but still correct my English in the separated section.

Start by greeting me and asking about my day.

What does this prompt do?

This prompt gives Gemini six clear rules that turn it from a chat partner into a structured coach.

The profile section tells Gemini your level (A2-B1), your native language (Estonian), and your interests. This means it pitches vocabulary slightly above your current level to stretch you.
Rules 1-2 force Gemini to add CORRECTIONS, EXPLANATION, and VOCABULARY sections after every single response. Without these rules, Gemini skips corrections entirely.
Rule 3 creates a built-in review cycle every 5 messages so vocabulary sticks in your memory.
Rules 5-6 give you control commands: PAUSE to ask grammar questions in Estonian, and SCENARIO to start roleplay practice.

✔️ Awesome, I've got everything!

Great. Make sure you pasted the full prompt into Gemini and pressed Enter.

ⓧ I'd like to double check the full code

Here is the complete coaching prompt. Make sure every line matches what you pasted into Gemini:

You are my personal English coach. Here is my profile:

- Current level: A2-B1 (pre-intermediate)
- Native language: Estonian
- Goals: Use English for college, workplace, and gaming
- Topics I enjoy: basketball, football (soccer), video games (Nintendo Switch), technology
- Preferred English: American English

Rules for every message I send:

1. Respond to my message naturally in English, at a level slightly above mine (use B1 vocabulary with occasional B2 words).

2. After your response, add a clearly separated section with:
   - CORRECTIONS: Fix any grammar, vocabulary, or spelling errors. Show wrong vs correct side by side.
   - EXPLANATION: Briefly explain why each correction is needed (the grammar rule) in simple English.
   - VOCABULARY: Highlight 1-2 new words from your response with pronunciation guide, definition, and one example sentence.

3. Every 5 messages, do a mini-review:
   - List all new vocabulary from the last 5 exchanges
   - Quiz me on 2 words from earlier in our conversation
   - Suggest one grammar pattern to focus on based on my mistakes

4. Keep your responses short and conversational. Do not write essays. Ask me one follow-up question at the end to keep the conversation going.

5. If I write PAUSE, switch to Estonian and let me ask any grammar question in Estonian. Explain the answer in Estonian. When I write RESUME, switch back to English practice.

6. If I write SCENARIO followed by a description, start a roleplay based on that scenario. Stay in character but still correct my English in the separated section.

Start by greeting me and asking about my day.

Gemini should respond with a friendly greeting and ask about your day. This is your coach saying hello.

Gemini not responding as a coach?

If Gemini responds like a normal chatbot without greeting you as a coach, make sure you pasted the entire prompt including the last line that says "Start by greeting me and asking about my day." Try starting a new chat and pasting the full prompt again.

Why is Gemini not acting as my English coach after I pasted the prompt?

Write your first coached message

Now that your coach is ready, it is time to test whether the corrections actually appear. Think about what you did today and describe it in English. Do not worry about making mistakes. That is the whole point.

Before you send your message, think: do you expect Gemini to correct your mistakes this time, or will it just chat like before?

In the same Gemini chat, type 3-4 sentences about what you did today. Use English naturally and do not try to be perfect. For example, write about what you ate, what game you played, or who you talked to.
Press Enter to send your message.

Look at Gemini's response. You should now see something completely different from Step 2. After the conversational reply, Gemini adds three clearly separated sections: CORRECTIONS (showing what you wrote wrong and the correct version), EXPLANATION (the grammar rule behind each fix), and VOCABULARY (new words with definitions and examples).

Why is this so different from Step 2?

Without the coaching prompt, Gemini optimizes for being a pleasant conversation partner. It assumes you want a smooth chat, not a grammar lesson. Your prompt overrides that default behavior by giving Gemini explicit rules: always correct, always explain, always teach vocabulary.

This is the core idea behind prompt engineering. The same AI becomes a completely different tool depending on the instructions you give it.

Not seeing the CORRECTIONS section?

If Gemini responded conversationally but did not include the CORRECTIONS, EXPLANATION, and VOCABULARY sections, your prompt may have been cut off during pasting. Start a new chat, paste the full prompt again from the code block above, and resend your message.

Help me figure out why Gemini is not showing corrections after my message.

Test the PAUSE and RESUME commands

Sometimes you need to ask a grammar question but cannot find the right English words to ask it. The PAUSE command lets you switch to Estonian, get your answer, and switch back.

In the same chat, type PAUSE and press Enter.
Gemini should acknowledge the switch and respond in Estonian.
Ask a grammar question in Estonian. For example, ask about when to use "a" vs "the" or when to use present perfect vs past simple.
Read Gemini's explanation in Estonian. It should answer your grammar question clearly in your native language.

Now type RESUME and press Enter.
Gemini should switch back to English coaching mode and ask you a follow-up question in English.

Why have a PAUSE command?

At the A2-B1 level, some grammar concepts are too complex to discuss entirely in English. The PAUSE/RESUME system gives you an escape hatch: ask the hard question in Estonian, understand the answer fully, then go back to practicing. You get the best of both languages.

PAUSE not switching to Estonian?

Make sure you type PAUSE in all capital letters on its own line. If Gemini still responds in English, try typing: "PAUSE - please switch to Estonian now" to reinforce the instruction.

Why is the PAUSE command not working in my coaching session?

Save your prompt for next time

Gemini does not remember your coaching prompt between sessions. Copy the prompt from the code block above and save it in a text file or Google Doc on your computer. Next time you want to practice, paste it into a new Gemini chat to start a fresh coaching session.

Your personal English coach is alive. Every message you send now gets corrections, explanations, and new vocabulary tailored to your level. Next up, you will put this coach to work in real-life scenarios: gaming conversations, college emails, and job interviews.

Practice Real-Life Scenarios

Your coach is working. It catches mistakes, explains grammar rules, and teaches vocabulary in every response.

Knowing grammar rules is useless if you cannot use English in situations you will actually face. Roleplay scenarios let you rehearse real conversations safely before doing them for real. In this step, you will practice both casual gaming English and formal college English, and see how your coach adapts its corrections for each context.

In this step, get ready to:

Practice casual English in a gaming roleplay scenario.
Practice formal English in a college application email scenario.
Save your mistake summaries and new vocabulary from each scenario.

Start a gaming roleplay

Gaming conversations use a specific kind of English. They are fast, casual, full of slang, and require quick callouts. Your coach can simulate teammates so you practice this style while still getting corrections on your grammar.

In your Gemini chat (the same one where your coach is active), start the gaming roleplay by typing this message:

SCENARIO I'm chatting with teammates in an online game. You play my teammates.

What does SCENARIO do?

The SCENARIO command is built into your coaching prompt. When Gemini sees it, the AI enters the roleplay character you described. It will pretend to be your gaming teammates while still giving corrections in the separated section after each response.

Gemini responds as your teammate, asking you something in casual gaming English. You should now see the AI staying in character.

Reply to your "teammate" with 3-4 messages. Use the kind of English you would actually type in a game chat. Talk about strategy, ask for help, or make callouts.
After each message you send, read the CORRECTIONS and VOCABULARY sections in the coach's response.

Notice how the coach teaches you gaming slang and casual phrases while still correcting your grammar. The VOCABULARY section now includes informal words you would actually hear in online games.

Coach not staying in character?

If Gemini drops the roleplay and starts responding as a generic assistant, type SCENARIO again with the same description. Sometimes the AI needs a reminder to stay in character after a few exchanges.

If the corrections section disappears, add a reminder at the end of your message: "Remember to include corrections."

Help me get my coach to stay in the gaming roleplay

Switch to a formal scenario

Formal English is a completely different skill from gaming chat. Words like "gonna" and "brb" that work in games would look terrible in a college application email. Your coach adjusts its corrections to focus on register, which means choosing the right level of formality for the situation.

Start a new roleplay by typing this message in the same chat:

SCENARIO I'm writing an email to apply for a college program.

Why practice formal English separately?

A college admissions office expects proper greetings ("Dear Admissions Committee"), complete sentences, and professional vocabulary. Your coach will now correct you differently. Instead of teaching slang, it focuses on formal register: proper greeting structure, sentence complexity, and professional word choices.

Gemini now responds as if it is guiding you through writing a real application email.

Write 3-4 messages practicing your email. Start with a greeting, explain why you want to join the program, and describe your interests.
After each message, read the CORRECTIONS section. Notice how the corrections now focus on formal vs informal choices.

Compare the corrections from this scenario to the gaming one. The gaming roleplay corrected grammar but accepted casual phrasing. The formal scenario flags any casual language and suggests professional alternatives.

Corrections look the same as gaming?

If your coach is not giving register-specific feedback (formal vs informal), try adding this to your next message: "Also tell me if any of my language is too informal for a college email." This reminds the AI to focus on formality level.

Help me get formal English corrections from my coach

Save your mistake summaries

Every practice session teaches you something, but you will forget it if you do not save it. Gemini does not remember previous conversations after a short time. Asking for a summary gives you a compact list of mistakes and vocabulary that you can copy and review later.

Before you ask for the summary, what do you think your coach will highlight as your most common mistake type across both scenarios?

Ask your coach for a summary of both scenarios by typing this message:

Give me a summary of my mistakes and 5 new words I should remember.

Why save this summary?

Gemini's free tier only retains your interactions for a short time. If you come back tomorrow, the AI will not remember today's practice. By copying this summary into a text file or a Google Doc, you build a personal record of your mistakes and new vocabulary that you can paste back into future sessions.

Your coach responds with a list of your mistakes from the roleplay sessions and 5 vocabulary words with definitions. This is your personal study list.

Select and copy the entire summary that Gemini gave you.
Open a new text file (Notepad on Windows) or a Google Doc.
Paste the summary there and save it. This becomes your first vocabulary and mistake log.

Get a summary for each scenario separately

If you want separate lists for gaming vocabulary and formal vocabulary, ask the coach: "Give me 5 new gaming words and 5 new formal words from our roleplays." This helps you organize your study notes by context.

Coach giving a vague summary?

If the summary is too short or does not list specific words, be more specific: "List my 3 biggest grammar mistakes with the wrong sentence and the correct version. Then list 5 new vocabulary words with definitions and example sentences."

Help me get a detailed summary from my English coach

You now have two types of English practice under your belt: casual and formal. Your saved summary is the start of your personal vocabulary log. Next up, you will build a system of targeted grammar drills and vocabulary exercises that attack your specific weak spots.

Build Your Grammar and Vocabulary Drill System

Your roleplay conversations gave you fluency practice and showed you how English works in different situations.

Conversations build fluency, but they do not fix specific weaknesses. By creating drill prompts for your worst areas (articles, prepositions, verb tenses), you build a system that attacks your exact gaps instead of practicing what you already know.

In this step, get ready to:

Run a 10-question grammar quiz targeting your weakest area.
Complete a vocabulary exercise about topics you enjoy.
Save reusable prompt templates and a weekly practice schedule.

Discover your grammar weaknesses and take a quiz

Your coach has been correcting you across multiple conversations. It can now identify patterns in your mistakes and turn them into targeted practice.

In your active Gemini coach chat, type the following message and press Enter:

Based on our conversations, what are my 3 biggest grammar problems? Create a 10-question quiz for my worst one.

Gemini responds with a list of your most common grammar mistakes and then starts a quiz. You should see question 1 appear, waiting for your answer.

What should I see?

Your coach identifies 3 grammar areas where you make the most errors. For Estonian speakers, these are often articles (a/an/the), prepositions (in/on/at), and verb tenses.

Then it presents the first quiz question as a fill-in-the-blank or error correction exercise.

Answer all 10 questions one at a time.
Type your answer to each question and press Enter.
After each answer, read the explanation before moving on to the next question.

Before you answer your final question, predict: what score do you think you will get out of 10?

After question 10, your coach gives you a score (X/10) and a summary of which grammar rules you need to review. If you scored below 7/10, it offers 5 more practice questions.

Do not worry about a low score

A low score means the quiz found exactly what you need to practice. That is the whole point of targeted drills. If you scored below 7/10, accept the extra 5 questions for more practice.

Now save a reusable version of this grammar drill prompt so you can practice any grammar topic in the future.

Open a text editor (Notepad on Windows) or a Google Doc.
Copy the following prompt and save it as grammar-drill-prompt.txt:

You are my English grammar coach. My level is A2-B1 and my native language is Estonian.

I want to practice: [WRITE YOUR TOPIC HERE - examples: articles (a/an/the), prepositions (in/on/at), verb tenses (present perfect vs past simple), word order]

Rules:
1. Give me 10 fill-in-the-blank or correction exercises, one at a time.
2. Wait for my answer before showing the next question.
3. After each answer, tell me if I am correct or wrong. If wrong, explain the rule in simple English with 2 example sentences.
4. After all 10 questions, give me a score (X/10) and a summary of which rules I need to review.
5. If I score below 7/10, offer 5 more practice questions on the items I got wrong.

Start with question 1.

What does this prompt do?

This is a reusable template you can paste into any new Gemini chat. Replace the bracketed topic with whatever grammar area you want to drill.

The rules ensure Gemini gives you one question at a time (so you actually think), explains each wrong answer, and offers extra practice if you score low.

Coach not giving you a quiz?

If Gemini just lists your grammar problems without creating a quiz, send a follow-up message: "Now create a 10-question quiz for my worst grammar problem. Give me one question at a time."

If it gives all 10 questions at once, reply: "Give me one question at a time. Wait for my answer before showing the next."

help me get Gemini to run a grammar quiz one question at a time

Build a vocabulary set for your interests

Vocabulary sticks better when it connects to topics you already care about. A vocabulary set about basketball or gaming gives you words you will actually use in real conversations.

Click New chat in the left sidebar of Gemini to start a fresh conversation.
Paste the following vocabulary builder prompt into the new chat:

You are my English vocabulary coach. My level is A2-B1 and my native language is Estonian.

Create a vocabulary lesson for this topic: [WRITE YOUR TOPIC - examples: basketball terms, gaming vocabulary, job interview words, college application phrases, everyday verbs]

Format for each word:
- Word (pronunciation): definition in simple English
- Example sentence using the word
- Estonian translation

Give me 15 words, then create a 10-question exercise:
- 5 fill-in-the-blank sentences using the words
- 3 "which word means..." definition matching questions
- 2 "write your own sentence using..." questions

Wait for my answers and then grade them with corrections.

Before pressing Enter, replace [WRITE YOUR TOPIC - examples: basketball terms, gaming vocabulary, job interview words, college application phrases, everyday verbs] with your chosen topic.
For example, replace it with basketball terms and game commentary vocabulary or gaming vocabulary for online multiplayer.
Press Enter to send the prompt.

Gemini responds with 15 vocabulary words (with definitions, example sentences, and Estonian translations), followed by a 10-question exercise.

Read through the 15 words and their definitions first.
Answer all 10 exercise questions and press Enter to submit your answers.

Gemini grades your answers and shows corrections for any wrong ones.

What does this prompt do?

This prompt combines learning and testing in one session. First you read new words with context (definitions, examples, translations). Then you immediately use them in exercises, which forces your brain to move the words from reading memory into active use.

Save the original template (with the bracketed placeholder) in your text file or Google Doc as vocabulary-builder-prompt.txt so you can reuse it for different topics later.

Missing Estonian translations?

If Gemini skips the Estonian translations, send a follow-up: "Please add Estonian translations for each word." Gemini sometimes skips parts of a long prompt, so a short reminder brings them back.

help me get Gemini to include all parts of my vocabulary lesson

Create your weekly practice routine

Having great prompts is useless if you do not use them regularly. A structured weekly schedule turns your collection of prompts into a real learning system.

Switch back to your original coach chat (find it in the left sidebar of Gemini).
Type the following message and press Enter:

Design a 5-day practice schedule for me (15 minutes per day). Alternate between conversation practice, grammar drills, vocabulary building, and writing correction. Include specific activities for each day.

Gemini responds with a day-by-day schedule showing exactly what to practice each day.

Copy the schedule Gemini gives you and save it in the same file or Google Doc where you keep your other prompts.

Finally, save the weekly review prompt that ties everything together. This prompt lets you paste your saved vocabulary notes from the week and get a review quiz.

Copy the following prompt and save it as weekly-review-prompt.txt:

You are my English review coach. My level is A2-B1 and my native language is Estonian.

Here are the words and grammar rules I learned this week:

[PASTE YOUR SAVED VOCABULARY AND GRAMMAR NOTES HERE]

Create a review quiz:
1. 5 vocabulary questions (mix of fill-in-the-blank and definition matching)
2. 5 grammar questions based on the rules I practiced
3. 1 short writing task: write 3-4 sentences using at least 3 of the vocabulary words

Grade my answers, give me a score (X/11), and tell me:
- Which words I know well (no more practice needed)
- Which words I need to review again next week
- Which grammar rules I still struggle with

End with one piece of encouragement about my progress.

What does this prompt do?

At the end of each week, you paste all the vocabulary and grammar notes you saved during your daily practice sessions into the bracketed section. The coach then quizzes you specifically on what you learned that week.

This is spaced repetition in action. Reviewing words a few days after you first learned them moves them from short-term memory into long-term memory.

Why save prompts when Gemini does not remember between sessions?

Gemini's free tier retains interactions for only 1 day. That means you cannot rely on it remembering your vocabulary from last week.

By saving your prompts and vocabulary notes externally, you become the memory. Each new session, you paste what you need and Gemini picks up exactly where you left off.

✔️ Awesome, I've got everything!

Great. Confirm you have saved all four files: english-coach-prompt.txt, grammar-drill-prompt.txt, vocabulary-builder-prompt.txt, and weekly-review-prompt.txt.

You now have a complete English learning toolkit: a coaching prompt for conversations, a grammar drill for targeted practice, a vocabulary builder for new words, and a weekly review to make sure nothing slips away.

Secret mission

Build Your "Level Up" Quiz System

You have been practicing English with your AI coach, but how do you know if you are actually improving? In this secret mission, you will build a spaced repetition system that tracks every new word you learn, quizzes you on previous sessions, and measures your level over time. This turns your practice from "hope I'm getting better" into proof.

Pause - I'll come back to this later

Since Gemini is free and browser-based, there is nothing to pause or shut down. Your prompts and vocabulary logs are ready whenever you return.

Make sure your prompt files are saved somewhere permanent (Google Doc or a text file on your computer) so you can find them later.
Save your vocabulary log with today's date so you know where you left off.
When you return, open a new Gemini chat and paste your coaching prompt to pick up where you left off.

Delete - I don't want to use this again

Remove all project resources if you do not plan to use your English coach again.

Delete your Gemini conversations: in the Gemini sidebar, hover over each practice conversation and select the delete option to remove it from your history.
Delete your saved prompt files: if you saved them in Google Docs, move them to Trash and empty the Trash. If you saved them as local text files, delete them from your computer.
Delete your vocabulary log file the same way (Google Docs Trash or local file deletion).

That's a Wrap!

Nice work! You just built a complete AI English coaching system using Google Gemini that gives you real-time corrections, grammar explanations, and vocabulary lessons tailored to your level and interests.

You've learned how to:

Used prompt engineering to transform a generic AI chatbot into a strict-but-friendly English coach that catches every mistake and explains the grammar rule behind it.
Practiced real-life roleplay scenarios including gaming conversations, college application emails, and formal writing, with corrections specific to each context.
Created targeted grammar drills and vocabulary builders that attack your specific weak spots, plus a weekly practice routine for continuous improvement.
Secret Mission: built a spaced repetition review system that tracks your vocabulary week by week and tests you on previous sessions to prove your progress.
