Google adds in-chat document creation and editing to Gemini app

The latest:

Documents, PDFs, presentations, spreadsheets and code can now be generated, previewed and edited directly inside the Gemini app, Google said in an October 29, 2026 product update. The company said the capabilities are live for all users in all languages where the app is available, with no staged rollout described. Files can be opened full screen for manual typing.

Details:

• The feature: Google said Gemini users can create and refine documents, PDFs, presentations, spreadsheets, code and other file types without leaving the conversation, replacing the previous pattern of exporting a draft to a separate application before any edit could be made.
• How editing works: According to Google, a generated file can be expanded to full screen so the user types edits directly into it. Text can also be highlighted to ask Gemini questions about that passage, or to instruct the model to rewrite it.
• Platform split: PDF preview and editing is supported on both web and mobile, Google said. Every other supported format — Google Docs, Google Sheets, slide decks, Markdown files, TXT files and code — is available on the web only, with no mobile date announced.
• The formats: The supported list named by Google covers Google Docs, Google Sheets, slide decks, Markdown, TXT and code files, alongside PDFs. Google did not say whether third-party office formats are handled or whether additional file types are planned.
• The demo case: Google illustrated the feature with a study guide: a user uploads handwritten lecture notes, asks Gemini to turn them into a PDF, then manually edits the result, highlights sections for the model to revise text or visuals, and asks follow-up questions on the same file.
• Visual edits: Beyond text, Google said highlighted sections can be sent back to Gemini for changes to visuals inside the file, extending the editing loop past wording into the document’s layout elements.
• Availability: The capabilities are described as already available rather than in preview or limited testing, and Google set no eligibility condition tied to a paid Gemini subscription tier in the announcement.
• What was not stated: Google did not specify a timeline for bringing the non-PDF formats to mobile, and named no enterprise or Workspace-specific controls accompanying the launch.

Background:

Gemini is Google’s consumer-facing assistant app, built around the company’s Gemini model family. Until this update, file output from the app largely ended at generation, leaving refinement to be done elsewhere.

Between the lines:

The platform split is the tell. PDF — the format most likely to be read and marked up on a phone — ships on mobile, while Docs, Sheets and slide decks stay on the web, where Google’s existing productivity suite already lives. That keeps the heavier authoring work close to the browser-based tools users already open for it, and positions the chat window as a place where a file is finished rather than merely started.

What’s next

Watch for a mobile release date for Docs, Sheets, slides and code editing, for any extension of supported formats beyond Google’s own, and for Workspace administrator controls governing the feature in managed accounts.
