The value of Gemini inside Google Workspace is that it reads what you already have. Open the side panel in Gmail, Docs, Sheets, Slides, or Drive and Gemini can pull from your threads, files, and calendar — you just point it at the right source. These 28 prompts are written for that side-panel behavior: reference an email or file by name, or type @ to attach the exact one. They run on Gemini 3.1 Pro (and the faster 3.1 Flash for lighter work), and use the ICC pattern — Intent, Context, Constraints — so you get a usable answer on the first pass. Replace every [bracketed] placeholder with your real values before sending. New to Gemini? Start with the best Gemini prompts roundup, then come back for the Workspace-specific set.

Gmail

Open the Gemini side panel inside a thread and it reads the whole conversation. These five cover the daily inbox jobs: summarize, reply, prioritize, extract, and brief.

1. Summarize a long Gmail thread

Summarize this email thread "[subject line]" in 5 bullet points. For each point, note who said it and any date or number mentioned. End with one line: "Open question / next step:" naming what is still unresolved and who owns it. Keep it under 120 words.

Best for: catching up on a 20-message chain in ten seconds.

2. Draft a reply in your voice

Draft a reply to this thread. Intent: [agree to the meeting / push the deadline to Friday / decline politely]. Match my usual tone — warm but concise, no filler openers. Reference the specific point [name] raised about [topic]. Keep it under 90 words, end with a clear next step, and leave [bracketed] blanks for anything you are unsure about.

Best for: replies that sound like you, not like a template.

3. Prioritize the inbox

Review my inbox from the last [2 days] and group emails into three tiers: "Reply today" (needs a response from me, time-sensitive), "Read when free" (FYI, no action), and "Can ignore / archive". For each in the top tier, give the sender, subject, and a 6-word reason it is urgent. List no more than 8 items in the top tier.

Best for: a Monday-morning triage pass before you touch anything.

4. Extract action items from a thread

From the thread "[subject line]", extract every commitment or task anyone agreed to. Return a table with columns: Owner, Task, Due date (or "none stated"), Source (who said it). Only include real commitments, not vague intentions. If a due date was implied but not stated, mark it "implied".

Best for: turning a messy decision thread into a clean task list.

5. Turn an email chain into a decision brief

Read this thread and write a one-page decision brief for someone who was not on it. Structure: Context (2 sentences), The decision needed, Options discussed (with the main pro and con of each), Where we landed, and Open items. Neutral tone, no more than 250 words. Flag anything where people disagreed.

Best for: looping in a manager or forwarding to a stakeholder.

Docs

In a Google Doc, the side panel can read the open document or any file you @-mention. These prompts summarize, outline, rewrite, structure, and proofread.

6. Summarize a long Doc

Summarize this document in three layers: (1) a one-sentence takeaway, (2) five key points as bullets, (3) any decisions, numbers, or deadlines called out. If the document contradicts itself anywhere, note it. Keep the whole summary under 150 words.

Best for: a 15-page report you have five minutes to grasp.

7. Outline a document from a brief

I need to write a [proposal / one-pager / project plan] about [topic] for [audience]. Create a detailed outline: a working title, 5-7 section headings, and 2-3 bullet points under each describing what that section should cover. Note where I will need real data or a chart. Do not write the full prose yet.

Best for: getting past the blank page with a real skeleton.

8. Rewrite for a specific audience

Rewrite the selected section for [a non-technical executive / a new hire / a client]. Keep every fact and number exactly as-is, but adjust the vocabulary and detail level for that reader. Cut jargon, shorten sentences, and lead each paragraph with its main point. Return only the rewritten text.

Best for: reusing one draft for two very different readers.

9. Turn notes into a structured report

Take my rough notes in this document and turn them into a structured report with clear headings: Summary, Background, Findings, Recommendations, Next steps. Keep my facts, fix grammar and flow, and use bullets where a list reads better than a paragraph. Do not invent details I did not include — mark gaps with "[need input]".

Best for: going from bullet-point notes to something shareable.

10. Proofread and tighten a Doc

Proofread this document for grammar, spelling, and consistency (dates, capitalization, terminology). Then flag any sentence that is wordy or unclear and suggest a tighter version. Present it as a list: "Original → Suggested" so I can accept changes one at a time. Do not change my meaning or tone.

Best for: a final pass before you hit send or share.

Sheets

Sheets is where Gemini does the most work: Fill with Gemini for columns, "build a table from Gmail or Drive", summaries, charts, cleanup, and formulas. Six prompts here.

11. Fill with Gemini: categorize a column

Using Fill with Gemini, categorize each row based on the [description in column B]. Assign exactly one label from this list: [Bug, Feature request, Billing, Other]. If a row does not clearly fit, use "Other". Output only the label, one per row.

Best for: tagging support tickets, feedback, or expenses down a column. Give it two example rows first, then let it extend the pattern.

12. Build a table from Gmail

Build a table in this sheet from my emails about "[project or subject keyword]" over the last [30 days]. Columns: Date, Sender, Subject, Key ask or update, Status (open/closed if stated). One row per relevant email, newest first. Skip newsletters and automated notifications.

Best for: turning a scattered email trail into a trackable log.

13. Summarize and analyze a data range

Analyze the data in range [A1:F200]. Tell me: the top 3 patterns or trends you see, any outliers or anomalies, and the single most important takeaway for [a sales review / a budget check]. Show the numbers behind each claim. If the data is too sparse to conclude something, say so instead of guessing.

Best for: a fast read on a table before you build the chart.

14. Generate a chart from a table

Create a chart from the data in [A1:C50] that best shows [monthly revenue by region]. Pick the chart type that fits the data (bar, line, or pie) and explain in one line why. Label the axes clearly and give the chart a plain-English title a reader would understand at a glance.

Best for: a presentable visual without fiddling with chart menus.

15. Clean and normalize messy data

Clean the data in column [C]: standardize the formatting so all entries follow the same pattern [e.g. "First Last", or dates as YYYY-MM-DD], trim extra spaces, and fix obvious typos in [company names]. Put the cleaned values in a new column beside the original so I can compare before applying. Flag any row you are unsure about.

Best for: tidying an imported CSV without a single formula.

16. Write a formula from a description

Write a Google Sheets formula that [sums column D only where column B equals "Paid" and column A is within the last 30 days]. Give me the exact formula ready to paste into cell [F2], then one sentence explaining what each part does. If a helper column would make it simpler, suggest that instead.

Best for: skipping the SUMIFS documentation entirely.

Slides

In Slides, Gemini can draft a deck outline, convert a Doc into slides, generate images, and tighten on-slide text. Four prompts.

17. Generate a slide deck outline

Outline a [10]-slide deck on [topic] for [audience, e.g. a client pitch]. For each slide give: a headline (the point, not a label), 3 bullet points, and a note on any visual or chart it needs. Slide 1 is the hook, the last slide is a clear call to action. Keep bullets to one line each.

Best for: a structured storyline before you design a single slide.

18. Turn a Doc into slides

Turn the document @[Doc name] into a presentation. Condense each major section into one slide with a clear headline and no more than 4 short bullets. Move dense detail into speaker notes rather than onto the slide. Suggest where a chart or image would land better than text.

Best for: reusing a written report as a talk. @-mention the source Doc so Gemini reads the exact file.

19. Generate an image for a slide

Generate an image for a slide about [topic]: [a clean, modern illustration of a team collaborating around a laptop, flat style, blue and white palette, plenty of empty space for text on the right]. Landscape orientation, no text baked into the image. Give me one option, then I will ask for variations.

Best for: an on-brand visual without hunting stock photos.

20. Rewrite slide text to be tighter

Rewrite the text on this slide so it fits a presentation, not a document. Turn full sentences into short, punchy bullets of 6 words or fewer. Keep the one key number. Move anything I would say out loud into speaker notes. Return the slide bullets and the notes separately.

Best for: fixing the classic wall-of-text slide.

Drive & search

From the Drive side panel, Gemini can find files by description, compare documents, and run Deep Research across sources. Four prompts here.

21. Find a file across Drive

Find the file in my Drive that [contains the Q3 budget I shared with finance around March]. I do not remember the exact name. List the top 3 matches with the file name, type, last modified date, and one line on why it matches, so I can pick the right one.

Best for: the document you know exists but cannot name.

22. Compare two documents

Compare @[Document A] and @[Document B]. Give me: what is the same, what changed or conflicts, and anything present in one but missing from the other. Present it as a three-column view. Focus on substance — numbers, dates, commitments — not wording.

Best for: checking a contract redline or two versions of a plan. @-mention both files.

23. Deep Research from Drive sources

Run Deep Research on [our top 3 competitors in the meal-kit market]. Ground your findings in current data with Google Search and cite every source. Then cross-reference against @[our positioning doc] and tell me where we are differentiated and where a competitor beats us. Deliver a structured brief with a sources list at the end.

Best for: a research memo that blends live web data with your own files. Use Deep Research (or Deep Research Max) for multi-source work.

24. Summarize a folder of files

Summarize the contents of the Drive folder "[folder name]". For each file, give a one-line description of what it is and when it was last updated. Then tell me overall: what this folder is for, which files look outdated, and whether anything obvious seems to be missing.

Best for: getting oriented in a shared folder you just inherited.

Calendar & Meet

Gemini reads your Calendar and Meet recordings too. These four prep agendas, summarize meetings, brief you before a call, and turn notes into follow-ups.

25. Draft an agenda from calendar and email

Draft an agenda for my [30-minute] meeting titled "[meeting name]" on [date]. Pull context from recent emails with the attendees about [topic]. Structure: 3-4 agenda items with a time box each, the decision or outcome we need from each, and any pre-read. Keep the total within the meeting length.

Best for: walking into a meeting with a real plan.

26. Summarize a Meet recording

Summarize the recording of "[meeting name]" from [date]. Give me: key decisions made, action items with owners and due dates, open questions, and any point where attendees disagreed. If someone committed to something, quote the gist. Keep it under 200 words and put action items in a table.

Best for: a meeting you missed or want on the record.

27. Prep for an upcoming meeting

I have a meeting "[meeting name]" on [date] with [attendees]. Prep me: summarize our recent email threads and any shared docs with these people, list what was decided last time and what is still open, and suggest 3 questions I should be ready to answer. Flag anything sensitive I should handle carefully.

Best for: a five-minute brief before an important call.

28. Turn meeting notes into follow-ups

From these meeting notes, draft the follow-up email to attendees. Lead with a two-line recap, then list decisions and action items (owner + due date), then next meeting if one was set. Keep it under 150 words, professional and clear. Leave a [blank] where I need to confirm a date.

Best for: closing the loop right after the call ends.

Frequently Asked Questions

Does Gemini really read my Gmail and Drive?

Yes. In the Workspace side panel, Gemini can read the emails, files, and events you already have access to — Gmail threads, Drive documents, Docs, Sheets, Slides, and Calendar entries. You reference them in plain language or with an @ file mention, and Gemini pulls the content into its answer. It only sees data your account can already open; it does not reach into other people's private files.

Is my Workspace data private when I use Gemini?

For paid Google Workspace and Workspace with Gemini plans, Google states that your prompts, responses, and the content Gemini accesses are not used to train its models and are not reviewed by humans, and the data stays inside your organization's existing security and compliance boundary. Consumer Gemini accounts have different terms, so check the plan you are on. Admins can also turn Gemini features on or off per organizational unit.

Which plan and model do I need for Gemini in Workspace?

Gemini side-panel features in Gmail, Docs, Sheets, Slides, and Drive require a Google Workspace plan that includes Gemini, or a Gemini add-on on top of a business or enterprise plan. The heavier reasoning runs on Gemini 3.1 Pro, while faster tasks use Gemini 3.1 Flash. Deep Research and Gems are available on the plans that bundle the AI features — check your admin console to confirm what is enabled.

How does Fill with Gemini work in Sheets?

Fill with Gemini lets you type a plain-language instruction for a column, and Gemini generates values for each row based on the other cells in that row. You give it a couple of example outputs or a clear rule, and it extends the pattern down the column — useful for categorizing, extracting, drafting short text, or normalizing data. Always spot-check the output, since it infers rather than calculates.

How do I @-mention a file or email in a Gemini prompt?

In the Workspace side panel, type @ and start typing the file or email name; Gemini shows matching Drive files, Docs, Sheets, Slides, and recent emails you can pick. Selecting one attaches its content to your prompt so Gemini reads that exact source. You can @-mention several files in one prompt to have Gemini compare or combine them.

What are Gems and should I use them for Workspace tasks?

Gems are saved custom assistants — a reusable set of instructions, tone, and context you configure once, then reuse. For recurring Workspace work like weekly status reports, inbox triage, or a specific writing style, build a Gem so you do not re-paste the same setup each time. You can give a Gem standing instructions such as "always summarize in five bullets" and it applies them to every request.

How do I adapt these prompts to my own data?

Replace every bracketed placeholder with your real values — the thread subject, file name, sheet range, date range, or recipient — and @-mention the specific email or file so Gemini reads the right source. Add one line of constraints (length, tone, format) and, for anything time-sensitive, tell Gemini to verify with Google Search grounding. Start with Medium thinking and raise it to High for complex analysis.

Can Gemini verify facts with current data?

Yes. Gemini 3.1 Pro supports grounding with Google Search, so you can add an instruction like "verify with current data and cite sources" and it will check live search results before answering. This matters for figures, prices, dates, and anything that changes — without it, the model answers from its training data, which has a cutoff.
