Build a Finance Brief with Gemini

Create and verify a cited Alphabet finance brief using Gemini and SEC filings.

Introduction

30 Second Summary

Company results can sound convincing while hiding where each number came from. A polished summary earns trust when a reader can trace its claims to the original report.

In this project, you will turn Alphabet's 2025 Form 10-K into a concise finance brief with Gemini. You will verify every key figure against the filing before publishing the brief in Google Docs.

What You'll Build

When you open your finished Google Doc, you can scan Alphabet's year-over-year results while following every key claim back to its SEC filing.

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

A verified metrics table that lets readers compare Alphabet's 2024 and 2025 revenue, income from operations, net income, and operating cash flow in consistent USD millions.
A clear split between reported facts from Alphabet and AI-assisted interpretation produced with Gemini.
A reusable citation audit that checks each figure's period, unit, source location, and match with the original filing.
Secret Mission: Reuse the workflow on Microsoft's fiscal 2026 results and add a period-aware comparison with Alphabet.

Are there any prerequisites?

You need Google Chrome, a Google Account, and a paid Gemini subscription.

Basic web browsing is enough. No accounting or coding experience is required.

Before We Start

Before any research begins, this checkpoint commits you to the intended reader and learning outcome for your evidence-checked finance brief. The brief provides educational analysis without a buy, sell, rating, or price-target recommendation.

Set Up Gemini and the Alphabet Source Pack

A reliable finance brief needs a fixed primary source before analysis begins. It also needs a confirmed research workspace.

You will confirm Deep Research access in Gemini. You will check Canvas in the same feature menu.

You will save Alphabet's Form 10-K from SEC EDGAR as a PDF. A cover-page question will confirm that Gemini received the right filing.

In this step, get ready to:

Confirm the research features available in Gemini.
Save Alphabet's official Form 10-K as a local PDF.
Upload the filing to Gemini for a cover-page verification.

Confirm Gemini research access

Gemini displays research features according to the signed-in account. This sign-in is a simple access check for the Google Account tied to your paid subscription.

Press Cmd+Space (macOS) or the Windows key (Windows) to open your search bar.
Type Google Chrome into the search bar.
Press Enter to open Google Chrome.
Enter https://gemini.google.com in the address bar.
Complete the sign-in flow with the Google Account tied to your paid Gemini subscription if Gemini asks.
Confirm that Gemini is using the Google Account tied to your paid subscription.

You should now see the Gemini prompt area under the confirmed account.

Click Add Files near the prompt area.
Check that Deep Research appears in the menu.
Check that Canvas appears in the menu.
Select Deep Research to view the research workspace.

The Deep Research workspace displays the model available to your account. That displayed model is the one you will use for this project.

Why use the offered model?

Gemini can offer different Deep Research models according to account access. Using the displayed model keeps the workflow aligned with the subscription you confirmed.

Missing Deep Research or Canvas?

Confirm that you are signed in to the Google Account tied to your paid subscription.
Reload Gemini after confirming the account.

Deep Research requires the user to be 18 or over. It also requires sign-in to Gemini.

help me find Deep Research or Canvas in my Gemini account.

Save Alphabet's filing as a PDF

SEC EDGAR holds Alphabet's official filing. A saved copy keeps the source fixed for every later evidence check.

Open Alphabet's official 2025 Form 10-K in Google Chrome.
Confirm that the cover page names Alphabet Inc. as the registrant.
Confirm that the cover page states For the fiscal year ended December 31, 2025.

These cover details establish which company the filing belongs to. They also establish the exact reporting period.

Press Ctrl + p to open Chrome's print preview.
Select Save as PDF as the destination.
Choose a local folder you can find again: your PDF folder.
Name the file Alphabet-2025-10-K.pdf.
Click Save to create the local PDF.

Good work. You now have a fixed local source that every later check can return to.

Can't find the saved PDF?

Repeat the print flow if the PDF does not appear in your PDF folder.
Check that the filename is exactly Alphabet-2025-10-K.pdf.

help me save Alphabet's SEC filing as a PDF in Chrome.

Verify the filing in Gemini

File identity comes before financial analysis. A cover-page-only question gives Gemini a narrow verification task.

Switch back to the Gemini tab from earlier.
Start a new Gemini chat.

You should now see a blank prompt area for the new chat.

Click Add files near the prompt area.
Click Upload Files to open the local file picker.

The local file picker lets you attach the fixed source you saved.

Go to your PDF folder in the file picker.
Select Alphabet-2025-10-K.pdf.
Complete the file selection to upload the PDF.

A long Form 10-K can take a moment to attach. You should see Alphabet-2025-10-K.pdf in the chat when the upload is ready.

Before you send the prompt, which company name and fiscal year should a cover-page-only answer return?

Send this cover-page verification prompt to Gemini:

Using only the cover page, state the registrant's exact name and fiscal year end.

Why use only the cover page?

The constraint keeps Gemini focused on file identity. It prevents later financial tables from influencing this first check.

Compare Gemini's response with the two cover details you checked earlier.

The response should identify Alphabet Inc. It should state the fiscal year ended December 31, 2025.

That is your first evidence check complete. Gemini has identified the filing from the filing itself.

Did Gemini identify the wrong filing?

Confirm that Alphabet-2025-10-K.pdf is attached to the chat.
Resend the exact cover-page prompt after confirming the attached filename.
Start a fresh chat if the response continues to use information beyond the cover page.

help me verify the uploaded Alphabet filing in Gemini.

Your source pack is ready. Next, you'll see how quickly a polished summary can outrun its evidence.

Test a First Draft

Your Alphabet source pack is ready. The cover-page check in Gemini confirms Alphabet Inc. for the fiscal year ended December 31, 2025.

A broad prompt can produce convincing financial metrics without a clear evidence trail. This step tests whether a polished summary gives you enough detail to defend every claim.

In this step, get ready to:

Generate a short unverified finance brief in a separate ordinary Gemini chat.
Request the exact source document, fiscal period, units, source location, and interpretation labels.
Document every number or risk claim with missing or ambiguous evidence.

Generate the broad first draft

An ordinary chat gives you a baseline for judging a plausible answer. Keeping the filing out of this chat leaves the broad request as Gemini's only context.

Switch back to the Gemini tab in Google Chrome.
Start a separate ordinary chat.
Confirm that Alphabet-2025-10-K.pdf is not attached to this chat.

Before you send the request, form a prediction about whether a fluent answer makes every figure easy to trace.

Request the first draft by sending this prompt:

Create a short finance brief on Alphabet's 2025 performance. Include revenue, operating income, net income, operating cash flow, and two business risks.

What Does This Prompt Test?

The request names four financial metrics. It also asks for two business risks.

The prompt supplies no fixed source or audit schema. This reveals how much evidence Gemini adds without tighter constraints.

You'll see a short Alphabet finance brief containing figures and risk claims. Its polished tone can make the underlying evidence gaps easy to overlook.

You now have the baseline that makes the audit meaningful.

Did the PDF Remain Attached?

Start another ordinary chat if the filename appears beside your prompt.
Check that no file is listed before you resend the prompt.

If the attachment keeps carrying over, help me create an ordinary Gemini chat without the previous PDF attachment.

Ask for an evidence trail

An evidence request tests whether each claim carries enough context to verify. The same request also tests whether Gemini separates reported information from its own interpretation.

Before you send the follow-up, form a prediction about how many claims already contain every requested evidence field.

Send this follow-up in the same ordinary chat:

For every number and risk claim, provide the exact source document, fiscal period, units, and source location. Label statements that are your interpretation.

What Does the Follow-Up Add?

The source document identifies where a claim came from.
The fiscal period identifies the year covered by a figure.
The units show the scale of each number.
The source location points to the relevant part of the document.
The interpretation label separates analysis from company-reported information.

You'll see a more detailed response. At least one number or risk claim should still have missing or ambiguous evidence.

This Shortfall Is Intentional

A follow-up request can add useful detail after the draft exists. It cannot guarantee that each original claim came from a controlled primary source.

Did the Follow-Up Stop Responding?

Retry the response if the chat stalls.
Resend the exact follow-up if the response ignores the requested evidence fields.

If the response still does not arrive, help me troubleshoot an ordinary Gemini chat that is not responding to my evidence request.

Audit every claim

Citation auditing checks whether a reader can retrace a claim to its evidence. Your audit records the exact gap instead of relying on a general feeling that the answer needs better sources.

Before you audit the responses, form a prediction about whether every claim passes all five evidence checks.

Review every number in the original draft.
Flag each number that lacks an exact source document.
Flag each number that lacks a fiscal period.
Flag each number that lacks a unit.
Review every risk claim in the original draft.
Flag each risk claim that lacks a source location.
Flag each claim that blurs reported fact with interpretation.
Record each flagged claim in the checkpoint below.

Your audit should identify every claim with an incomplete source location, period, unit, or fact-versus-interpretation distinction.

Before you compare your notes with the chat, form a prediction about whether each note names both the claim and its missing evidence.

Compare your submitted audit notes with the first-draft chat.

You should see every unsupported number or risk claim paired with at least one missing evidence field.

You have turned a convincing first draft into a concrete map of its weaknesses.

Your audit notes are ready. Next up, you'll use those gaps to shape a controlled research workflow.

Generate a Source-Grounded Report

Your first draft showed how polished writing can still leave every important claim hard to defend.

Now you'll use Deep Research in Gemini to control the evidence trail. Alphabet's uploaded filing becomes the report's only source.

In this step, get ready to:

Limit Deep Research to Alphabet's uploaded Form 10-K.
Submit a research request with fixed metrics and evidence rules.
Review the research plan before generating the report.

Lock the report to the filing

A primary source gives every financial claim a fixed point of reference. Deselecting Google Search keeps this report grounded only in Alphabet-2025-10-K.pdf.

Return to the Gemini tab from earlier.
Start a new chat.

You'll see an empty prompt area for the new research task.

Select Add Files in the prompt area.
Choose Deep Research.

You'll see Deep Research selected for the chat. It uses the research model available to your account.

Select Add Files again.
Choose Files.

The Windows file picker opens so you can choose the saved filing.

Upload Alphabet-2025-10-K.pdf from the folder where you saved it.

You should see Alphabet-2025-10-K.pdf attached beside the prompt.

Open Sources.
Deselect Google Search.

The source selection should now contain the uploaded filing. Google Search should be deselected.

Define the research schema

A research schema gives Gemini a consistent structure for collecting evidence. It keeps each value attached to a period, unit, label, and source location.

Place a constrained research request in the message box by copying the prompt below:

Create a beginner-friendly finance brief for Alphabet Inc. for the fiscal year ended December 31, 2025. Include a table with the exact 2024 and 2025 values for Revenues, Income from operations, Net income, and Net cash provided by operating activities. Preserve the filing's USD millions unit. Explain each metric in plain English, identify two risks directly supported by Item 1A, cite the source location for every factual claim, separate reported facts from interpretation, and do not provide investment advice.

What Does This Request Control?

The two-year table makes every metric directly comparable across periods.
The USD millions requirement preserves the filing's unit.
The Item 1A requirement anchors both risks to Alphabet's risk disclosures.
The final constraints separate evidence from interpretation. They also keep investment advice outside the report's scope.

Submit the request by selecting Submit.

Gemini should create a research plan before gathering evidence. This plan lets you inspect the proposed work before the report begins.

Did Gemini Skip the Research Plan?

An immediate answer can mean Deep Research was not selected. Return to the tool selection and confirm that Deep Research is active before submitting the request again.

Ask for help if the plan still does not appear: help me confirm that my Gemini chat is using Deep Research

Review the plan and generate the report

The research plan is your chance to catch missing requirements before generation. This checkpoint prevents the evidence gaps you found in the first draft.

Review the plan for a two-year table covering Revenues, Income from operations, Net income, and Net cash provided by operating activities.
Confirm that the plan preserves the filing's USD millions unit.
Confirm that the plan requests source locations for factual claims.
Confirm that the plan includes two risks supported by Item 1A.
Confirm that the plan separates reported facts from interpretation.
Select Edit plan if any required element is missing.
Add the omitted requirement using the wording from your submitted request.

Before you start the research, which weaknesses from the first draft do you expect this plan to prevent?

The report usually takes about 5-10 minutes. A quiet progress screen during that wait is normal.

Start the report by selecting Start research.

You'll see progress while Deep Research reads the filing and assembles the report.

Open the completed report by selecting Open.

You've closed the biggest evidence gap. The report now has a controlled source and a reviewed research plan.

Before you inspect the metric table, do you expect all four 2025 values to match the filing?

Locate the metric table in the completed report.
Confirm that the table includes columns for 2024 and 2025.
Confirm that the table identifies the unit as USD millions.
Check the four entries in the 2025 column.

What Should You See?

The Revenues value should be 402,836.
The Income from operations value should be 129,039.
The Net income value should be 132,170.
The Net cash provided by operating activities value should be 164,713.

Check that each metric has a plain-English explanation.
Check that two risks point back to Item 1A.
Check that factual claims include source locations.
Check that reported facts are separated from interpretation.
Check that the report contains no investment advice.

Strong work. You now have a beginner-friendly report grounded only in Alphabet's filing.

Is the Report Missing Evidence?

If the report cites web results, confirm that Google Search was deselected before the research began. If a required section is missing, update the plan with the omitted wording from your original request and run the research again.

Ask for help with the specific gap: help me diagnose why my Deep Research report missed a required source or section

Your source-grounded report is ready. Next, you'll audit its figures against the SEC filing and make the fact-versus-interpretation boundary explicit.

Audit Metrics and Labels

Your source-grounded Deep Research report now contains the evidence your brief needs. A citation makes each claim traceable.

However, an AI report can still misread a column or blur evidence with opinion. You'll audit the four metrics against Alphabet's Form 10-K.

You'll then give facts explicit labels. The finished report will separate the filing's statements from the analysis.

In this step, get ready to:

Compare the report's four metrics with Alphabet's financial statements.
Complete a verification table with no unresolved mismatches.
Label reported facts and interpretations throughout the analysis.

Compare the report with the filing

Financial statements place several years beside each other. This makes column shifts easy to miss when a report extracts figures.

The statement headings can be fiddly to find in a long filing. Use the exact headings below to anchor each check.

Switch back to Alphabet's SEC filing from earlier.
Scroll to CONSOLIDATED STATEMENTS OF INCOME.
Compare the report's 2024 and 2025 values for Revenues.
Compare the report's 2024 and 2025 values for Income from operations.
Compare the report's 2024 and 2025 values for Net income.
Scroll to CONSOLIDATED STATEMENTS OF CASH FLOWS.
Compare the report's 2024 and 2025 values for Net cash provided by operating activities.

What should the filing show?

Under CONSOLIDATED STATEMENTS OF INCOME, Revenues is 350,018 in 2024. Its 2025 value is 402,836.
Under CONSOLIDATED STATEMENTS OF INCOME, Income from operations is 112,390 in 2024. Its 2025 value is 129,039.
Under CONSOLIDATED STATEMENTS OF INCOME, Net income is 100,118 in 2024. Its 2025 value is 132,170.
Under CONSOLIDATED STATEMENTS OF CASH FLOWS, Net cash provided by operating activities is 125,299 in 2024. Its 2025 value is 164,713.

The income statement labels its unit as (in millions, except per share amounts). The cash flow statement labels its unit as (in millions).

Complete the verification table

A verification table places the Gemini value beside the filing value. Each row records the evidence needed to resolve a mismatch.

Return to the Deep Research report from earlier.
Add the audit structure by entering this follow-up request:

Add a verification table with columns for metric, period, Gemini value, filing value, unit, source section, and status.
Create one row for each metric and period.

What does this request do?

The two value columns expose any disagreement between the report and the filing. The remaining columns preserve the period, unit, source section, and resolution status.

Enter one 2024 row and one 2025 row for each metric.
Copy each value currently shown in the report into the Gemini value column.
Copy each manually checked value into the filing value column.
Enter USD millions in every unit cell.
Enter the matching financial statement heading in each source section cell.
Correct every mismatch in the report before continuing.
Update the table after each correction so both value columns agree.
Record a matching status only after checking both values against the filing.

You should see eight completed metric-period rows. Every row should show agreement between the report and the filing.

Missing a column or seeing a mismatch?

Compare the table header with the seven requested columns. Ask Gemini to regenerate the table if a column is missing.

If the values disagree, return to the relevant statement heading. Check the year column before correcting the report.

Ask for help with auditing a financial metric mismatch.

Label facts and interpretations

A checked number can still be presented with an unsupported conclusion. Explicit labels show readers where the filing ends and the analysis begins.

Rewrite the report's analysis by entering this follow-up request:

Rewrite the analysis with two explicit labels:
Reported fact: Use this label for filing-backed statements.
Interpretation: Use this label for conclusions.

Do not remove the completed verification table or filing citations.

Include this exact limitations note:
Educational analysis of public information. This is not investment advice, and past results do not predict future performance.

Why do these labels matter?

Reported fact identifies a statement supported directly by the filing.
Interpretation identifies a conclusion drawn from those reported results.
The limitations note defines the educational scope of the brief.

Review every metric statement in the rewritten analysis.
Confirm that filing-backed statements use Reported fact.
Review every conclusion drawn from the reported results.
Confirm that those conclusions use Interpretation.
Follow the source location for each risk claim to Item 1A.
Correct any risk claim that the cited section does not support.
Confirm that the exact limitations note appears in the report.

Seeing inconsistent labels?

Check that descriptions of filing values use Reported fact. Check that conclusions about what those values mean use Interpretation.

Ask for help with separating financial facts from interpretations.

Before the final scan, do you think any unsupported sentence or unresolved mismatch remains?

Scan the verification table for unresolved mismatches.
Scan the analysis for both labels.
Scan the report for the exact limitations note.

You should see no unresolved mismatch across all eight metric-period rows.

The analysis should use both labels. Its two risk claims should point to Item 1A.

The exact limitations note should appear in the report.

That's the evidence check complete. Next, you'll shape the verified report into a finance brief that readers can scan in Google Docs.

Publish the Finance Brief

Your Deep Research report now has verified figures. Its risk claims have citations.

The analysis also separates reported facts from interpretation. A reader still needs a clear path through the evidence.

Gemini Canvas turns that checked analysis into a brief readers can scan. The final export in Google Docs gives them a document they can share.

In this step, get ready to:

Shape the verified report into an eight-section Canvas document.
Make the report's evidence boundaries easy to scan.
Produce a visually checked Google Docs export.

Shape the verified report in Canvas

A concise structure helps readers find the numbers first. It also gives every interpretation a clear place.

What belongs in each section?

Executive Snapshot summarizes the most important results.
Verified Metrics presents the checked 2024 and 2025 figures in USD millions. It includes the plain-English explanations.
What Changed explains the year-over-year direction of each metric.
Key Risks presents two filing-backed risks from Item 1A.
Interpretation contains conclusions that are explicitly labeled as analysis.
Verification Notes records that the audited values have no unresolved mismatches.
Sources keeps the link to Alphabet's official 2025 Form 10-K.
Limitations states the educational purpose of the brief.

Switch back to the completed Deep Research report from earlier.
Open the verified report in Canvas.
Set the document title to Alphabet 2025 Finance Brief.
Arrange the Canvas document to match the eight-section order shown above.

You should now see Alphabet 2025 Finance Brief at the top. All eight section headings should appear beneath it.

Edit for clarity and evidence boundaries

Publishing keeps the audit trail visible while making the report easier to read. Clear labels prevent filing-backed statements from blending into analysis.

Keep the evidence boundary visible

Reported fact identifies statements supported directly by the filing. Interpretation identifies conclusions drawn from those statements.

The Limitations section keeps this exact note: "Educational analysis of public information. This is not investment advice, and past results do not predict future performance."

Shorten repeated explanations with Canvas editing.
Preserve the evidence labels throughout the document.

You should now be able to spot every Reported fact label. Every analytical conclusion should carry the Interpretation label.

Keep a citation beside each risk claim.
Keep the SEC filing URL in the Sources section.

Each risk should lead back to supporting evidence. The source section should retain the official filing link.

Place the exact educational-analysis note in the Limitations section.
Remove all investment-recommendation language.

The document should contain no price target. It should contain no rating or buy or sell recommendation.

Export and inspect the Google Doc

The export is the publication checkpoint. A final visual review confirms that the evidence survives the move from Canvas.

Before you export, predict whether the Google Doc will preserve all eight sections.

Select Share & export in Canvas.
Choose Export to Docs.

You should see a new Google Doc open in Chrome. Its title should be Alphabet 2025 Finance Brief.

Confirm the document title.
Scan the document for all eight headings listed earlier.
Inspect the Verified Metrics table.

The table should show all four metrics for 2024 and 2025 in USD millions. Its values should match your completed verification table with no unresolved mismatches.

Read the plain-English explanation for each metric.
Confirm that both risks have citations.
Confirm that Verification Notes records the completed audit.
Select the SEC filing link under Sources.

You should see Alphabet Inc.'s official Form 10-K open. The filing should cover the fiscal year ended December 31, 2025.

Return to the exported Google Doc in the browser tab from earlier.
Read the Limitations section.
Scan the document for any price target, rating, or buy or sell recommendation.

The limitations note should match the audited report exactly. You should find no investment recommendation.

Strong finish. Your verified finance brief is now published in Google Docs with its evidence boundaries intact.
