Gemini Prompt Generator
Build a context-aware prompt for Gemini, including Docs, Sheets, and Gmail. Free, no sign-up.
Gemini can see the document, sheet, or thread you have open inside Google Workspace -- this tool builds a prompt that actually references that context instead of writing a standalone request as if starting from nothing.
How to use it
Be specific about what you want Gemini to do, not just the general topic.
Background Gemini can't infer -- your audience, your goal, what matters most -- improves the result.
Docs, Sheets, and Gmail each benefit from referencing the open document directly rather than a generic standalone request.
Tips for better results
- Reference the open document explicitly when using Workspace: Gemini in Docs, Sheets, or Gmail can see what you have open -- naming it directly ("looking at this document") uses that context automatically.
- Standalone prompts need more context: Outside Workspace, Gemini has nothing to reference but what you type -- be more explicit about background than you would inside an app.
- Image generation prompts work differently: For image requests, skip the app field and focus on a clear, specific description of what to create.
Example output
“Looking at this docs, summarize the key decisions. Context: a project planning doc with three competing proposals.”
Why these prompt elements matter
Task and context matter here the same way they do for any AI chat tool, but the app field is what makes this generator specifically useful for Gemini rather than a generic AI prompt tool. Gemini’s real advantage inside Google Workspace is that it can see the document, sheet, or thread you already have open — a prompt that references that context directly (“looking at this document…”) uses information Gemini already has access to, while a prompt that ignores it forces you to manually re-explain content Gemini could have read itself.
This is why the app selector changes the generated prompt’s opening structure rather than just adding a label. Selecting Docs, Sheets, or Gmail produces a prompt that explicitly references the open document; selecting general chat or image generation produces a standalone request that provides all its own context, since there’s no document for Gemini to reference in that mode.
Where Gemini’s behavior genuinely differs from other AI chat tools
Outside of Workspace integration, Gemini’s core prompting behavior follows the same task-context-format principles that apply to ChatGPT, Claude, and most other AI chat tools. The document-awareness inside Workspace apps is the genuinely distinctive piece, and it’s worth leaning on deliberately rather than defaulting to standalone-style prompts out of habit carried over from other tools. See the Gemini for Google Workspace guide for this in more depth. If you’re used to prompting ChatGPT and switching to Gemini inside a Google Doc, remembering to reference the document directly, rather than pasting its content back in manually, is the single biggest adjustment worth making.
Common mistakes this structure helps avoid
The most common mistake when prompting Gemini inside Workspace is not leveraging document-awareness at all — pasting document content manually into a standalone-style request when Gemini could already see it directly. This produces working results, but it’s slower and misses the actual advantage of using Gemini inside the app rather than a separate chat window. If you find yourself copying and pasting content into a Gemini prompt while working inside a Doc or Sheet, that’s usually a sign to reference the document directly instead.
A second common mistake is treating every Gemini request identically regardless of app context — using the same generic phrasing inside Sheets that would work fine in a standalone chat, without the added structural precision that spreadsheet data benefits from, like naming exact column headers or the specific pattern being analyzed.
When a standalone approach still makes sense inside Workspace
Not every task inside a Workspace app benefits from document-awareness — a genuinely new brainstorm or a question unrelated to the current document doesn’t gain anything from Gemini’s context-reading, and a standalone-style prompt works just as well in that situation. Recognizing when a task is really about the open document versus when it’s an unrelated request happening to occur inside a Workspace app helps you choose the right prompt style rather than defaulting to one approach regardless of fit.
FAQ
Does selecting an app actually change the generated prompt?
Yes — selecting Docs, Sheets, or Gmail produces a prompt that explicitly references the open document, which uses Gemini’s built-in context-awareness in that app.
What if I’m not working inside a specific Workspace app?
Select “General / standalone chat” — the generated prompt will provide its own full context rather than assuming a document Gemini can see.
Does this work the same way for Gemini’s image generation?
Image generation benefits from more visually descriptive language than text tasks — selecting that option adjusts the generated prompt’s structure accordingly.
Should I still add extra detail to the generated prompt?
Often yes, especially for Sheets tasks — naming specific column names or exact data patterns beyond what the fields capture tends to improve results further.
