Deep Research Mode is built for the questions that take an associate a full afternoon - the ones where you need to read multiple cases, cross-reference statutes, and synthesize a position. It runs an iterative research loop that drafts an answer, identifies what is missing, runs follow-up searches, and refines.Documentation Index

When To Use It
Use Deep Research for questions that need more than one pass:- “Compare how the Second and Ninth Circuits have treated implied warranty disclaimers in software licenses”
- “Walk me through the elements of promissory estoppel in California and identify which our facts satisfy”
- “What is the current status of personal jurisdiction over foreign defendants after the recent Supreme Court decisions?”
- “Analyze this complaint and tell me which causes of action are strongest given the case law”
How It Works
When Deep Research is on, the system:Higher Retrieval Limits
Deep Research pulls a larger pool of candidate sources before narrowing down - so the model can compare more authorities and pick the best ones rather than working with the first few that match.| Setting | Standard Mode | Deep Research |
|---|---|---|
| Candidate sources per query | Standard pool | Expanded pool |
| Follow-up queries | None | Up to 3 rounds |
| Cross-document synthesis | Single pass | Iterative |
| Best for | Direct questions | Comparative analysis |
Gap Analysis Between Rounds
After each round, the system asks itself: “What is this draft missing? Are there counter-authorities? Is there a temporal issue? Are the cases still good law?” The follow-up queries it generates are aimed at those gaps, not just at re-searching the original question. You can see the intermediate reasoning steps in the response - what was searched, what was found, and what was decided.Hallucination Guard
Each round runs through claim-level verification before the answer is returned. If the model writes a sentence that is not actually supported by the retrieved sources, the system flags it and re-runs that section. See Answer Verification for how this works.When To Turn It Off
- Quick lookups (“what is the citation for Marbury v. Madison?”)
- Drafting tasks that do not need research (“draft me an NDA”)
- Conversational follow-ups inside an existing thread
How To Enable
Click the Deep Research toggle in the chat composer. The toggle saves per matter, so if you turn it on for a litigation matter, it stays on while you work in that workspace.Tips
