Google Gemini Introduces In-Chat File Preview and Editing for All Users

According to media reports, Google announced on October 29, 2026, that the Gemini app has added in-chat file preview and direct editing capabilities, allowing users to modify generated PDFs, Google Docs, Slides, and Sheets without leaving the conversation interface. The feature is accessible to both free and paid users. Building upon the file generation feature introduced in April of the same year, this update addresses the previous workflow requirement of downloading files or exporting them to Google Drive for editing. Official documentation indicates three modification methods: direct manual typing in full-screen mode, selecting specific text or tables to issue targeted prompts, and providing conversational instructions to alter text or visual elements. Supported formats include PDF, Google Docs, Sheets, Slides, Markdown, TXT, and code. In terms of device limitations, the mobile app currently supports previewing and editing only for PDF files, while all other formats require the web version. Practical tests note that AI element replacements, such as converting tables to charts, may overwrite original tables, requiring users to manually verify content structure and terminology.
