The honest take

✓ What works

Used by 40%+ of AmLaw 100 firms — battle-tested in production
GPT-4 quality specifically tuned for legal language and reasoning
Massive multi-jurisdiction coverage (US, UK, EU, APAC)
Vault feature turns firm knowledge into a queryable AI
Backed by Sequoia, Kleiner Perkins, OpenAI Startup Fund

✗ What doesn't

Enterprise pricing ($1,000+/mo per seat) — solo lawyers priced out
Closed beta — must request access, waitlist can be weeks
Not a substitute for actual legal judgment (per their own disclaimer)
Requires clean data — won't fix a firm's document hygiene problem

Verdict

Harvey AI is a must-have for law firms. The $1,000+/mo pricing is fair, and the gpt-4 fine-tuned for law feature alone is worth trying the free tier.
