Deep research

Answer in brief

An AI workflow that plans a question, searches many sources and writes a report in which each claim cites its source.

What it means

Deep research goes beyond a single search. The tool first breaks a question into smaller parts, searches for each part, reads the results and decides what to look up next. The final step is a written report. A good report separates what the sources say from what the tool infers, and it lists the sources it used.

For professionals, the value lies in the time saved on collection and in the audit trail. A market analyst can get a first pass on a question in one session, then check the key figures.
