Harvey

Harvey sits in a peculiar niche: it's not a chatbot you prompt, and it's not a full-blown legal automation suite. It's a workflow agent that actually executes multi-step legal tasks with minimal hand-holding. I've watched it draft a 15-page memo on Delaware corporate law, pulling from case law and firm precedents, then refining citations based on feedback—all without me specifying each step. That's the autonomy: you describe the outcome, it plans the research path, drafts, and iterates. Where it shines is in high-volume, high-stakes diligence. During an M&A review, I pointed it at a data room with 400 contracts and asked it to flag change-of-control provisions and termination rights. It returned a structured table with clause summaries and risk ratings in under two hours. A junior associate would've taken three days. The agent doesn't just search—it synthesises, compares clauses across documents, and spots inconsistencies. That's worth the enterprise price if you're billing by the hour. Failure modes are predictable: it struggles with truly novel legal questions where there's no clear precedent to pattern-match against. I asked it to draft arguments for a niche IP dispute involving AI-generated works, and it produced boilerplate that missed the nuance. It also can't handle anything requiring judgement calls about client risk appetite—it'll flag every conceivable issue without prioritising. You still need a human to decide what matters. Compared to Casetext's CoCounsel, Harvey feels more opinionated and autonomous. CoCounsel is faster for one-off research queries, but Harvey's workflow agents actually complete tasks end-to-end. The trade-off: Harvey requires more upfront setup (you'll spend time configuring firm-specific precedents and tone) and it's enterprise-only, so no solo practitioners need apply. The API is solid if you want to embed it in your document management system. I've seen firms pipe Harvey outputs directly into contract lifecycle tools. But the web interface is where most users will live, and it's functional rather than delightful—think legal software, not consumer app. One concrete workflow: I use it to draft first-pass responses to regulatory inquiries. I feed it the inquiry letter and relevant policy docs, it drafts a response with citations, I review and edit. Cuts my drafting time by 60%, and the output is defensible enough that I'm comfortable putting my name on it after review.
