How professionals use deep research
Deep research works with authenticated sources, approved URLs, and apps to produce more credible, actionable reports.

Deep research prioritizes connected sources — private files, apps, paid datasets, and approved URLs — and delivers citation-backed reports you can verify quickly.
Edit the plan, refine focus, update sources, or interrupt at any time. Track progress in real time and get 30-minute reports in what would otherwise take hours or days.
Deep research delivers higher-quality outputs with reduced latency. Analyze markets, review regulations, compare scientific literature, or synthesize long technical documents with structured, long-context reasoning.
Administrators can manage access to apps, enforce source controls, and ensure sensitive data stays within the right teams.
