Generate and Edit Documents Directly in Gemini

You no longer need to copy text out of a chat and paste it into another app. The Gemini app now lets you generate a document, preview it in the conversation, and edit it on the spot. PDF editing works on both web and mobile. Other formats stay on the web for now.

This update arrived on October 29, 2026, and is available to every Gemini user in every language the app supports. It builds on the file-generation feature that launched earlier in the year.

What you can create and edit

Gemini can produce these file types inside a chat:

• PDFs
• Google Docs
• Google Sheets
• Slide decks
• Markdown files
• Plain text (TXT)
• Code

PDF preview and editing work on the web and in the mobile apps. All other formats require the web version at gemini.google.com. You can expand any preview to full screen, type changes yourself, highlight a section and ask Gemini about it, or tell Gemini to refine that part.

How to generate a file

1. Open the Gemini app on the web or mobile.
2. Upload source material if you have any (lecture notes, a photo of handwritten pages, or an existing outline).
3. Ask for a specific format. Example: “Turn these handwritten notes into a one-page PDF study guide with headings and five practice questions.”
4. Wait for the preview to appear in the chat.

The preview shows the finished file. You can read it before you change anything.

Three ways to edit

Once the preview is open, you have three options.

Type your own changes. Expand the preview to full screen and click or tap into the text. Edit the same way you would in any document editor. Changes save automatically.

Highlight and ask. Select a paragraph, table, or image. Type a request such as “show this as a graph instead” or “make this section shorter.” Gemini updates only that part.

Refine the whole file. Ask Gemini to change tone, length, or structure across the entire document. The preview refreshes with the new version.

PDF editing works the same on a phone. For Docs, Sheets, slides, Markdown, TXT, or code, switch to the web version.

Example: study guide from handwritten notes

Google’s own demo starts with a photo of handwritten lecture notes. Upload the photo, ask for a PDF study guide, then:

• Expand the preview and fix a heading by typing.
• Highlight a table and ask Gemini to turn it into a chart.
• Ask a follow-up question about one section.

The finished PDF can be downloaded or saved to Drive. The same notes can also become a Google Sheet or a short slide deck if you stay on the web.

Export and next steps

After you finish editing:

• Download the file directly.
• Save PDFs, Docs, Sheets, and other formats to Google Drive.
• Open a Google Sheet or slide deck in its native app for further work.

If you already keep course materials in Gemini Notebook, you can pull those sources into the same chat and turn them into an editable study guide. See our guide on adding free textbooks to Gemini Notebook for the catalog steps.

Tips for better results

• Name the exact format in your first prompt (“as a PDF,” “as a Google Sheet”).
• For slide decks, ask for an outline first. Fix the order in the chat, then request the full deck.
• For spreadsheets, specify columns and any formulas you need before Gemini builds the table.
• Review numbers, names, and citations in the preview. Highlight any section that looks off and ask for a correction.
• On mobile, stick to PDFs until other formats gain full editing support.

Limitations to know

PDF is the only format that supports preview and editing on both web and mobile. Everything else is web-only right now. The feature generates and edits files that Gemini creates inside the chat; it is not a full replacement for desktop editors. Always check the final preview before you share or submit the file.

Conclusion

The Gemini app now turns a prompt and optional upload into a previewable, editable file. Start with a clear request, use the three editing methods to refine the result, and export when it looks right. The process works for study guides, trackers, short decks, and quick documents without leaving the chat.
