Harvey AI

Harvey is an AI platform built specifically for legal and professional services. It comes from Counsel AI and ranks among the best-funded legal AI tools ever, with a multi-billion-dollar valuation. It targets top-tier law firms (BigLaw) and in-house legal teams, replacing hours of routine legal work with assistance from AI tuned to legal language and workflows.

The principle is simple: you upload contracts, case materials, or legal documents, and Harvey analyzes them, answers questions, and drafts text. Crucially, every output comes with source citations, so you can verify each claim. It works over your own documents as well as legal, regulatory, and tax knowledge.
