Gemini can now make and edit documents right inside the chat

Google announced on October 29, 2026, that the Gemini app can now generate, preview and edit files right inside a chat. That covers documents, PDFs, presentations, spreadsheets, Markdown, plain text files and code. The catch: on phones, PDFs are the only format Google says you can preview and edit. The rest works on the web only.

What changed

Gemini could already make files you could download, thanks to an April 2026 update. Now it can open them in a full-screen editor. You can type changes yourself, or highlight a section and ask Gemini to rewrite it. That means no more copying text into another app, fixing it, and pasting it back for another pass.

Google's own example is a student who uploads a photo of handwritten lecture notes and asks for a polished PDF study guide. Then they highlight a paragraph and ask Gemini to simplify it or add detail, all in the same chat.

Phone or computer

• Web app at gemini.google.com: generate, preview and edit all the supported file types.
• Gemini mobile app: preview and edit PDFs only.
• Docs, Sheets, slide decks, Markdown, text and code files: web only.

Google's post does not say whether a phone's mobile browser counts as "web" for this feature. For resumes, reports, proposals or slide decks, a laptop or other computer is the safe choice.

Who can use it

Google says the features are available to all users in all languages where the Gemini app is available. The announcement does not mention a paid plan requirement or plan-specific limits.

What is not known yet

Google has not published a button-by-button guide, so exact menu names are unclear. Look for an option to expand the file to full screen after Gemini makes it. There is also no verified comparison with ChatGPT, Claude or Microsoft 365 Copilot, and no independent tests yet. Whether the highlight-to-edit tool holds up in real use remains to be seen.
