Google has supercharged its Gemini Deep Research tool to scan users’ Gmail inboxes, Google Drive files, and Chat conversations, marking a significant leap in how the AI assistant generates comprehensive research reports. The update, described by Google as “one of our most-requested features,” begins rolling out today on desktop, with mobile support arriving within days.Deep Research—an AI agent specifically built for creating multi-page reports rather than quick answers—can now pull insights from emails, documents, spreadsheets, presentations, PDFs, and chat logs alongside traditional web searches. This means users can command the AI to analyze team brainstorming documents while simultaneously reviewing related email threads and project plans, or build competitor analyses that merge public web data with internal strategy memos and team discussions.

How to use Gemini’s Deep Research feature with Gmail, Drive and Chat

Since launching in December 2024 with Gemini 1.5 Pro, Deep Research has evolved through Gemini 2.0 Flash Thinking to the current Gemini 2.5, delivering increasingly sophisticated analysis. The system can process hundreds of pages during research sessions, leveraging Google’s million-token context window to maintain coherence across extended tasks. It operates asynchronously—users can close their computers and receive completion notifications later—while an error recovery system prevents full task restarts if individual steps fail.The feature is available to all Gemini users at gemini.google.com, expanding the AI’s capability from purely web-based research to personalised investigations that tap directly into users’ digital workspaces.
