What I like most is that Harvey is built around legal work product, not open-ended chat. The assistant is genuinely useful for drafting and summarizing, and for asking grounded questions where it provides sources you can open and verify. Vault is the real differentiator on document-heavy matters: you can upload a large set, run structured extraction or cross-document questions, and get review tables or issue-oriented output rather than having to read every file linearly. That combination changes the economics of first-pass diligence, contract sets, and research memos. The Word/Outlook workflows help it fit into how lawyers already work, and the enterprise security posture—controls and the promise of no training on client data—makes it easier to use on real matters than a consumer LLM. When it’s used well, it feels less like “AI for AI’s sake” and more like a very fast junior associate that still needs partner-level judgment.

Harvey AI saves us hours on legal research and contract review with great context accuracy. It handles heavy groundwork like summarizing clauses and drafting memos, letting our team focus on strategy. It feels like having a super-fast junior associate 24/7.

It is very useful for working with legal documents and large amounts of information. I like how quickly it can analyze documents, summarize complex information, and help organize research. It can save a lot of time when reviewing contracts, preparing documents, or looking for specific information. This AI does it in less time, saving me a lot of time and effort and making my work easier.
