Google Brings In-App Document Editing and Preview to Gemini on Mobile and the Web

Core update

Google has brought in-app document editing and preview to Gemini across mobile and the web, according to an update published on Google's news blog. The change lets users create custom files inside Gemini and then interact with a preview to request further revisions, rather than only receiving a generated document and starting over.

What users can do

After Gemini generates a file, users can point to what needs changing in the preview and explain their edits. Google says the process combines text and visual input, allowing the model to update the document and show a preview straight away. The goal is to narrow the gap between a first draft and a finished document where details match what the user expects.

File support by platform

The mobile app supports PDFs. Gemini on the web can handle a larger variety of file types, including PDFs, spreadsheets, presentations, and code, as described in Google's blog post.

Why it matters

Document work often requires several rounds of feedback. By keeping editing, previewing, and revision requests inside Gemini, the update gives users a more direct way to refine outputs. The wider file support on the web makes the feature more useful for varied document tasks, while PDF support on mobile extends the same preview-based workflow to phones.
