Google Gemini Adds Direct Document and PDF Editing in Its App

What Is New

Google says the Gemini app now lets users create, preview and edit files directly inside a chat. In a post published on 29 October 2026, the Gemini Blog said the update covers documents, PDFs, presentations, spreadsheets, code and other formats [1].

Users can expand a file to full screen and type edits directly. They can also highlight text to ask Gemini questions, or ask Gemini to refine the file [1].

PDF preview and editing are supported on both the web and mobile. All other formats, including Google Docs, Google Sheets, slide decks, Markdown files, TXT files and code, are supported on the web only [1].

The features are available to all users in all languages where the Gemini app is available, according to Google [1].

Separately, a Google AI for Developers guide dated 26 October 2026 describes how to build apps in Google AI Studio. In Build mode, a user describes the app in an input box, and the tool generates the code and files, with a live preview shown on the right-hand side [2].

Why It Matters for Students

Google’s example shows a student uploading handwritten lecture notes and asking Gemini to create a PDF study guide. The student can then edit the guide manually, highlight sections so Gemini changes the text or visuals, and ask further questions [1].

How to Use It

For documents in the Gemini app, Google’s post describes these steps:

• Generate, preview or edit a file within your chat [1].
• Expand the file to full screen to type edits directly [1].
• Highlight text to ask a question, or have Gemini refine the file [1].

For developers using Google AI Studio, the guide describes these options:

• Enter a description in the input box in Build mode. You can select AI Chips to add features such as image generation or Google Maps data, or use the speech-to-text button [2].
• Use the “I’m Feeling Lucky” button to have Gemini generate a project idea and prompt [2].
• Remix a project from the App Gallery by opening it and selecting Copy App [2].
• Import existing code from GitHub by selecting Import from GitHub in the Add files menu [2].
• View generated code in the Code tab of the preview pane [2].
• Export code as a ZIP file, or connect the app to a GitHub repository for two-way sync [2].

Limits, Privacy and Academic Integrity

The editing limits depend on the format. PDF preview and editing are available on web and mobile, while other formats are available on the web only [1].

In Google AI Studio, the guide says API calls count toward your usage limits when you share an app. If you use paid models, costs may apply [2].

The sources do not describe privacy controls for uploaded files or rules on academic integrity for these features.
