Google adds file editing inside Gemini chats, with mobile support limited to PDFs

A file created in Gemini no longer has to leave the conversation for revisions. Google introduced in-chat file creation, previews and editing on October 29, 2026, covering documents, PDFs, presentations, spreadsheets and code. Users can make changes directly or ask Gemini to refine the file, rather than treating its first output as a finished download.

Two ways to change the same draft

Gemini already let users generate and download files. As Digital Trends explains, the change is that users can now work on those files inside the chat. The update brings revision into the same place as the request that produced the document, presentation or spreadsheet.

The editor offers both hands-on changes and AI assistance. Users can expand a file to full screen and type edits themselves. They can also highlight text to ask questions or have Gemini refine the content. Direct editing and prompting are both available within the file workflow; users do not have to rely on one method for every change.

Google demonstrates the sequence with a study guide made from uploaded handwritten lecture notes. A user asks Gemini to create a PDF, then manually edits the result or highlights sections for Gemini to change. The example includes revisions to text and visuals, as well as follow-up questions about the material. It shows creation, correction and questions as parts of one conversation.

Broad access, narrower mobile support

The platform distinction is important when choosing where to work. Google’s PDF study-guide example can be previewed and edited on either web or mobile. Working with the other listed formats—including documents, spreadsheets and presentations—requires the web version. The announcement does not offer the same editing coverage across both interfaces.

Account access is broader than that device split. Google says the capabilities are available now to all users, in all languages where the Gemini app is available. The release is not presented as a paid-subscriber-only feature; the practical restriction Google specifies is which file formats users can work with on each platform.
