Google's AI assistant in Drive will now search your Gmail inbox when you ask it a question.
The company is expanding Ask Gemini in Drive to let users add Gmail threads as sources for AI-generated summaries, answers, and cross-referenced workplace insights. Until now, Ask Gemini in Drive was limited to content already inside Drive itself. The update effectively collapses the wall between your inbox and your documents, treating your email history as a knowledge base you can query without leaving a spreadsheet or a deck.
Microsoft has been selling exactly this kind of cross-app AI integration with Copilot for over a year, pitching the idea that your productivity suite should know everything you've written, sent, and stored. Google making the same move matters because Workspace has a large enterprise installed base that has been watching Microsoft's rollout carefully — and this gives those customers one less reason to switch. The real differentiator in AI-assisted productivity is no longer what the model can do; it's which apps it can see.
The framing here is "add Gmail as a source," which sounds optional and controlled. What it means in practice is asking Gemini to rummage through your email while you edit a document — a trade-off Google is betting most users will wave through without much thought.
