What can you now edit directly inside the Gemini app?

Google has added a built-in editor to the Gemini app that lets you generate, preview, and modify files without leaving the chat. The change turns the conversation window into a workspace where you can type, highlight, and ask for revisions in the same place.

What the update actually adds

The Gemini app now creates files and lets you edit them inline. You can ask for a document, a spreadsheet, a slide deck, a PDF, Markdown, plain text, or code. Once the file appears, a full-screen view opens so you can type changes yourself. You can also highlight any passage and ask Gemini to rewrite, reformat, or explain that selection. The announcement shows a study guide built from handwritten lecture notes; after the PDF appears, the user edits text manually, highlights a section for Gemini to adjust, and then asks follow-up questions.

Where each format works

PDF preview and editing work on both the web and mobile versions of the app. Every other format — Google Docs, Google Sheets, slide decks, Markdown files, TXT files, and code — is limited to the web interface. The blog post does not say whether mobile support for those formats is planned.

How the editing loop works

You start with a prompt that produces a file. The file opens in an expanded pane. You type directly in that pane. It works. You highlight a sentence or a paragraph. You can also highlight a table cell and send a new instruction tied to that selection. Gemini applies the change and updates the preview. You can repeat the cycle as many times as needed. The demonstration shows the loop running on a PDF, but the same mechanics apply to every supported format on the web.

Who gets it and when

The features are rolling out to all users in every language where the Gemini app is already available. The post gives no staggered schedule, no regional exceptions, and no version numbers. It also does not say how many existing users have already received the update.

What the announcement leaves out

There is no mention of file size limits, offline access, or export options beyond the formats listed. The post does not address whether the editor stores revision history or how it handles conflicts when multiple people edit the same file. It also does not say whether the mobile PDF editor supports the same highlight-and-ask workflow shown for the web.
