Build a Gemini Notebook Infographic

Create and fact-check a source-grounded event infographic with Gemini Notebook.

Introduction

30 Second Summary

A community event poster has only seconds to answer the questions that matter. A polished design can still fail when key details are missing or misleading.

In this project, you will turn two short event briefs into an infographic using source grounding in Gemini Notebook. You will finish with an audited portrait visual ready to download as a PNG.

What You'll Build

Picture opening your downloaded PNG to see NORTHSTAR GROWS TOGETHER leading a clear portrait design for local families.

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

A source-grounded notebook that answers questions using two structured event briefs.
A visible untargeted baseline that shows why default generation can miss a required headline.
A fact-checked portrait infographic that highlights the event details plus three numeric callouts for local families.
Secret Mission: Reframe the same verified facts as a square child-friendly infographic headed GROW, LEARN, AND EXPLORE.

Are there any prerequisites?

You'll need a personal Google account, internet access, Safari on a Mac, plus eligibility for the 18+ Infographic feature in a supported region.

Before We Start

An infographic stays grounded when it begins with clear source material. A fixed audience and headline give you a concrete standard for judging every generated visual.

Before preparing those sources, you need to confirm that Safari can reach Gemini Notebook. You also need a personal Google account that meets the Infographic eligibility requirements.

In this step, get ready to:

Commit to the audience and required headline for your final infographic.
Confirm Safari and Gemini Notebook Standard access.
Verify that your account meets the Infographic eligibility requirements.

Lock in the project promise

Your finished visual is a source-grounded event infographic for local families and first-time gardeners. The exact headline NORTHSTAR GROWS TOGETHER creates a visible requirement that you can audit later.

Why Fix the Headline Now?

The required headline gives you a clear test for the first generated visual. If the default result omits it, you have specific evidence that the generation needs stronger direction.

Use the checkpoint below to describe the output, audience, and purpose of the fixed headline.

Confirm Safari and Standard access

Gemini Notebook Standard is free with a personal Gmail account. This project does not require a Gemini API key.

Press Cmd+Space to open Spotlight Search.
Type Safari and press Enter to open it.
Visit the official Gemini Notebook web app in Safari.
Select Sign in if Gemini Notebook requests authentication.
Complete the Google sign-in flow with your personal Google account.
Leave Create new notebook unselected on the signed-in home page.

You should see the Gemini Notebook home page with Create new notebook available. Your personal Google account now has the Standard access needed for this project.

Unable to Reach the Home Page?

Confirm that Safari can load another website before retrying Gemini Notebook.
Check that you completed sign-in with a personal Google account.
Reload the page after completing any Google account verification request.

Ask for help to troubleshoot Gemini Notebook access.

Confirm Infographic eligibility

The Infographic feature is available only to users over 18. Gemini Notebook browser access also depends on being in a supported country or territory.

Open the official Infographic feature guide in a new Safari tab.
Confirm that the holder of your personal Google account is over 18.
Review the official Gemini Notebook access requirements for regional availability.
Confirm that your current country or territory is supported.

Why Stop Before Creating a Notebook?

This preflight confirms that your browser and account can use the required workflow. The next step creates the project notebook with the correct name and source structure.

Before the final check, do you expect the signed-in home page to be ready without any Northstar project content?

Return to the signed-in Gemini Notebook tab.
Confirm that Create new notebook is visible.
Keep your account menu closed so your email address stays out of the checkpoint screenshot.

You should see the signed-in home page without a Northstar notebook or source material. That preflight is complete: Safari works, Standard access is ready, and your account meets the Infographic requirements.

Your access is ready. Next, you will create the Northstar notebook and ground it in two trusted source briefs.

Set Up Your Source-Grounded Notebook

An open-ended image prompt gives an AI model room to drift from the facts. Source grounding ties every later output to trusted event details.

A Gemini Notebook uses selected source material to answer questions and complete requests. You’ll add two structured briefs so the Chat panel can produce a grounded summary.

In this step, get ready to:

Create the Northstar Garden Open Day notebook.
Add both trusted source briefs.
Verify the source-grounded Chat output.

Create the notebook

The notebook gives both briefs one shared workspace. Its name also makes the project easy to find when you return later.

The sign-in uses your confirmed Google account. No API key or billing setup is involved.

Navigate to the Gemini Notebook website in Safari.
Complete the Google sign-in flow with your confirmed account.
Select Create new notebook.
Enter Northstar Garden Open Day as the notebook name.
Confirm the notebook name using the on-screen control.

You should see the Northstar Garden Open Day notebook open in Gemini Notebook.

Notebook did not open?

Check that Safari is signed in with the Google account you used to confirm access. Return to the notebook creation screen after switching accounts.

Ask for targeted help with the account flow: help me open my Gemini Notebook with the correct Google account.

Add the event brief

The event brief anchors the operational facts that visitors need. It covers the schedule, location, entry details, visitor guidance, and accessibility.

Select Add sources in the left panel.
Choose Copy and pasted text as the source type.
Set the source title to Northstar Garden Open Day: Event Brief.
Paste the event brief into the source form using the following text:

Northstar Garden Open Day is a fictional community event.

Date: Saturday 18 October 2026
Time: 10:00 AM to 2:00 PM
Location: Northstar Community Garden, 24 Willow Lane, Riverside
Entry: Free

Scheduled demonstrations:
10:30 AM: Composting for small spaces
11:30 AM: Seed planting for beginners
12:30 PM: Guided garden tour

Visitors should bring a reusable water bottle and wear closed-toe shoes. The main paths are wheelchair accessible. A quiet rest area and an accessible toilet are available near the entrance.

What does this source establish?

The logistics section anchors the event’s date, time, location, and free entry.
The schedule defines the exact time for each demonstration.
The visitor guidance preserves the accessibility details and what-to-bring advice.
Copied text gives every learner the same fixed facts. Changing webpages cannot alter this project’s source material.

Use the form’s confirmation button to add the copied-text source.
Check the Sources panel for Northstar Garden Open Day: Event Brief.

You should see the event brief listed as the notebook’s first source.

Event brief missing?

Return to the copied-text source form. Confirm that the source title contains the full event brief name before submitting it again.

Ask for help checking the source flow: help me add the event brief as a copied-text source.

Add the communications brief and inspect the summary

The communications brief defines the audience and message. It also prevents limited supplies from becoming guaranteed giveaways in later outputs.

Select Add sources in the Sources panel.
Choose Copy and pasted text as the source type.
Set the source title to Northstar Garden Open Day: Communications Brief.
Paste the communications brief into the source form using the following text:

The fictional Northstar Garden Open Day is designed for local families and first-time gardeners. Its message is that gardening can be welcoming, practical, and community-led.

Organizers have prepared 120 free seed packets and 40 compost starter kits. Both are available while supplies last. The event includes three scheduled demonstrations, four activity zones, and a staffed welcome desk.

The infographic should make the date, time, location, free entry, accessibility information, and what-to-bring guidance easy to find. It should not promise that every visitor will receive a seed packet or starter kit.

What does this source establish?

The audience section focuses the message on local families and first-time gardeners.
The quantities section records the available seed packets and compost starter kits.
The availability wording prevents the infographic from promising supplies to every visitor.
The content priorities identify which practical details must remain easy to find.

Use the form’s confirmation button to add the copied-text source.
Select the checkbox beside Northstar Garden Open Day: Event Brief in the Sources panel.
Select the checkbox beside Northstar Garden Open Day: Communications Brief in the Sources panel.

Before you inspect the result, which event facts do you expect the Chat panel to prioritize from the two selected sources?

Review the generated summary in the Chat panel.

You should see both source titles in the Sources panel with both selected. The Chat panel should show a generated summary grounded in those sources.

The summary’s exact wording can vary. Its claims should reflect the event logistics, intended audience, and limited-supply wording from the briefs.

Summary does not reflect both sources?

Check the selection controls beside both Northstar source titles. The Chat panel can only ground its summary in the sources included in the current scope.

Ask for help checking the source scope: help me confirm both Northstar sources are selected.

Your notebook now has a trusted factual foundation. Next, you’ll generate the first infographic directly from these selected sources.

Generate the Untargeted Baseline

Your two source briefs now give Gemini Notebook a controlled fact base for Northstar Garden Open Day.

A one-click infographic gives you an early visual result. This baseline reveals which presentation choices the default generation makes from the sources alone.

In this step, get ready to:

Keep the generation grounded in only the two Northstar sources.
Generate a default infographic without customization.
Identify the visible gap in the completed baseline.

Confirm the source scope

Source grounding starts with a controlled evidence boundary. Every selected source can shape the infographic.

In the Sources panel from earlier, confirm that Northstar Garden Open Day: Event Brief has a checkmark.
Confirm that Northstar Garden Open Day: Communications Brief has a checkmark.
Confirm that no additional source has a checkmark.

You should see only the two Northstar sources selected. This proves the baseline uses the same evidence as the grounded chat summary.

Generate with default settings

The Studio panel turns selected sources into source-based outputs. Choosing Infographic directly starts a default generation.

The pencil customization control opens the presentation settings. Leaving it untouched preserves a true default baseline.

Find Infographic in the Studio panel on the right.
Leave the pencil customization control untouched.

This output generates in the background. It may take a couple of minutes to complete.

Before you start the generation, what presentation choices do you think the default will make from the two sources alone?

Select Infographic directly to start the default generation.
Wait for the infographic to finish generating in the Studio panel.

Generation still pending?

Gemini Notebook can defer an output when a flexible usage limit is reached.

Return to the same notebook after the usage limit refreshes.
Select the deferred infographic when it completes.

Help me troubleshoot a deferred infographic generation.

Inspect the deliberate shortfall

The completed image is your untargeted baseline. It shows what the selected sources produce before you supply presentation requirements.

Before you open the result, do you think an exact headline that was never supplied will appear by chance?

Select the completed infographic in the Studio panel to open the Infographic viewer.
Compare its displayed headline with NORTHSTAR GROWS TOGETHER.

You will see a complete infographic. The required headline NORTHSTAR GROWS TOGETHER is absent.

What Did the Default Decide?

The generation received no required headline. It received no palette.

The generation received no audience hierarchy. It received no three-callout layout.

The default had to choose every presentation detail. The missing exact headline gives you an objective failure to improve.

That first generation has done useful work. You now have a concrete baseline that exposes the cost of unstated presentation requirements.

Your grounded evidence now has a visible design gap. Next up, you will direct the infographic with explicit presentation choices.

Direct the Final Infographic

Your baseline proved that source grounding alone does not decide which message should dominate the page. The missing headline made that gap visible.

Now you will use Gemini Notebook customization controls to define the family audience. A custom prompt will pin down the required headline and visual hierarchy.

In this step, get ready to:

Set the final infographic’s language, detail, orientation, and style.
Direct the audience, headline, palette, hierarchy, and factual boundaries.
Verify that the customized infographic fixes the baseline’s visible shortfall.

Set the visual controls

Visual controls give the generation a clear presentation frame before the prompt handles content priorities. Portrait orientation creates a top-to-bottom reading path for the event information.

Return to the Studio panel in the notebook from earlier to find the Infographic controls.
Select the pencil control beside Infographic to open its customization controls.
Set Output language to English.
Set Level of detail to Standard.
Set Orientation to Portrait.
Set Visual style to Professional.

You should now see English, Standard, Portrait, and Professional selected.

Why This Combination?

Portrait orientation gives the headline and essential event details a natural place at the top. The Professional style supports a clear information order for families planning a visit.

Add the audience and hierarchy prompt

The selected sources supply the factual boundary. The prompt tells the model which audience and information priorities should shape the page.

Fill the custom prompt field by pasting this text:

Create a welcoming event infographic for local families and first-time gardeners. Use the exact headline “NORTHSTAR GROWS TOGETHER” and an emerald green and sunflower yellow palette. Put the date, time, location, and free entry at the top. Highlight exactly three numeric callouts: 120 free seed packets, 40 compost starter kits, and 3 scheduled demonstrations. Clearly state that the packets and kits are available while supplies last. Include the accessibility details and a short “What to bring” section. Use only facts from the selected sources.

How Does This Prompt Guide the Visual?

The audience instruction focuses the language on local families and first-time gardeners.
The required headline gives the event one dominant message.
The top-level details establish what visitors need to find first.
The three-callout limit prevents secondary numbers from competing for attention.
The source-only instruction keeps the generation inside the two selected briefs.

Confirm that the prompt begins with Create a welcoming event infographic for local families and first-time gardeners.
Confirm that the prompt includes the exact headline NORTHSTAR GROWS TOGETHER.
Confirm that the prompt ends with Use only facts from the selected sources.

Prompt Looks Incomplete?

Click once inside the custom prompt field before pasting the complete text again.
Check the first sentence and final sentence to confirm that Safari pasted the whole prompt.

Help me check why my Gemini Notebook custom prompt is incomplete.

Generate and compare the result

The same two Northstar sources remain selected, so this generation stays grounded in the event briefs. The new controls tell Gemini Notebook how to present those facts.

This generation can take a couple of minutes because the infographic runs in the background. A short wait is normal.

Before you generate the new version, consider which difference you expect to notice first.

Start the customized generation using the control at the bottom of the customization panel.
Wait for the new infographic to finish in the Studio panel.
Open the completed customized infographic from the Studio panel.

Compare the opened customized infographic with the untargeted baseline from earlier.
Confirm that the exact headline NORTHSTAR GROWS TOGETHER is displayed.
Check that the visual uses an emerald green and sunflower yellow palette.
Check that Saturday 18 October 2026, 10:00 AM to 2:00 PM, Northstar Community Garden, 24 Willow Lane, Riverside, and free entry sit at the top.
Count the highlighted numeric callouts.
Locate the while supplies last wording for the packets and kits.
Confirm that the accessibility details and What to bring section are visible.

You should see a portrait infographic with the exact headline at the top of its information hierarchy.

You should find exactly three numeric callouts: 120 free seed packets, 40 compost starter kits, and 3 scheduled demonstrations.

You should also see while supplies last, accessibility details, and a What to bring section.

You have closed the baseline gap with a family-focused infographic whose headline and information order are intentional.

Still Waiting for the Infographic?

Gemini Notebook can defer an output when a flexible usage limit is reached. Usage limits refresh every five hours.

Wait a couple of minutes before checking the Studio panel again.
Return after the usage limit refreshes if the output has been deferred.

Help me understand why my customized infographic is still processing.

Your family version now has deliberate visual direction. Next up, you will audit every displayed claim before downloading the final PNG.

Audit and Download the Final PNG

Your customized infographic in Gemini Notebook now presents the event for local families and first-time gardeners. However, polished design can make an unchecked claim look convincing.

A polished layout becomes trustworthy only after every displayed claim matches its selected sources. Your final PNG also needs limited-supply wording that avoids a guarantee.

In this step, get ready to:

Audit the family infographic against both selected source briefs.
Repair any claim that fails the source audit.
Save the approved visual as a local PNG.

Audit the Displayed Facts

Source grounding connects each displayed claim to the wording that supports it. This keeps design choices from changing operational facts.

Treat a missing detail as a failed claim. Treat a limited item without its availability wording as an inaccurate promise.

Your Audit Checklist

The event date is Saturday 18 October 2026.
The event time is 10:00 AM to 2:00 PM.
The location is Northstar Community Garden, 24 Willow Lane, Riverside.

At the end of this pass, you know whether the current visual is approved or needs one precise regeneration.

Correct Any Failed Claim

A precise correction keeps the successful layout while directing attention to one unsupported claim. This protects the visual hierarchy you already established.

A direct correction quotes the exact source value. That wording gives the next generation a clear factual target.

Select the tab that matches your audit result.

✔️ Every Fact Matches

Every displayed claim matches the two selected sources. The current family infographic is ready for approval.

Keep the current infographic as the approved version.

ⓧ A Fact Needs Correction

Return to the Studio panel from earlier.
Select the three dots menu next to the family infographic.
Choose View custom prompt.
Copy the displayed custom prompt.
Use the pencil control for a new Infographic.

Keep the Correction Narrow

A narrow repair reduces the chance of unrelated facts drifting. Preserve the existing audience instructions while correcting the failed claim.

Set Output language to English.
Set Level of detail to Standard.
Set Orientation to Portrait.
Set Visual style to Professional.
Paste the copied instructions into the custom prompt field.
Append one direct correction that quotes the matching source value.

The replacement may take a couple of minutes to generate in the background. A short wait here is normal.

Start the corrected generation.
Open the completed result.
Repeat the source audit above.

You should see the corrected source value in the replacement visual. Every other audited claim should still match its source.

Generation Still Pending?

Gemini Notebook may defer an output when a flexible usage limit is reached. The deferred generation can complete later.

Leave the generation in the notebook until it finishes.
Repeat the audit after the completed result becomes available.

Ask for help if you need it: help me understand why my Gemini Notebook infographic is still pending.

That is the trust work done. Your approved family infographic now earns its polished appearance with verified facts.

Rename and Download the Approved PNG

Renaming before download keeps the approved file easy to identify in Safari's Downloads list. The local copy becomes your shareable deliverable.

The downloaded PNG preserves the exact visual that passed your audit. Its filename also separates it from earlier generations.

Return to the Studio panel from earlier.
Select the three dots menu next to the approved infographic.
Choose the rename option.
Enter Northstar Garden Open Day - Final as the new name.
Apply the new name.
Select the three dots menu next to the renamed infographic.
