An AI platform for lawyers whose agents draft, review and research legal work.

Why 3: its agents carry out multi-step work such as due diligence and contract review, but lawyers remain responsible for anything filed, so output is checked before it is used.
What it does. Harvey offers purpose-built and custom agents for work such as due diligence, contract review, drafting and legal research, including inside Microsoft Word. In March 2026 it said more than 100,000 lawyers at about 1,300 organisations used it and that over 25,000 custom agents ran on the platform. In September 2026 it raised $550 million at a $15.5 billion valuation and said 80% of Am Law 100 firms use it.
Where it falls short. We found no independent evaluation of its accuracy, in a profession where accuracy is the product. Lawyers remain responsible for anything filed in their name.
