Harvey closed a $300M Series F at a $5B valuation in early 2025, anchoring a category where Big Law procurement budgets finally make AI a real line item. Buyers split clearly: Harvey, Legora, and DeepJudge sell to elite firms for research, drafting, and institutional knowledge search. Spellbook, Lexion, and Draftwise specialize in contract review and negotiation, often for in-house legal teams. EvenUp dominates personal injury demand-letter automation; Eve Legal extends that pattern to plaintiff intake and litigation. Robin AI focuses on legal-document Q&A. Most enterprise pitches now demand sourced citations, hallucination logs, and on-prem or single-tenant deployment to clear bar-association ethical opinions.

FAQ
Frequently asked
Harvey vs Legora vs Spellbook — when do you pick which?
Harvey is the default for AmLaw 100 firms doing research and complex drafting. Legora is the European challenger, strong in collaborative review. Spellbook is the SMB and small-firm choice, embedded in Word and priced per seat rather than enterprise license.
Is AI-drafted legal work ethical under ABA Model Rules?
ABA Formal Opinion 512 (2024) confirms lawyers can use generative AI but must verify outputs, protect client confidentiality, and consider whether to disclose use. Cite-checking, conflict screening, and supervision obligations all remain on the human attorney.
How are AI legal tools priced for in-house teams?
Lexion, Spellbook, and Robin AI sell per seat at $50-300/month. Harvey and Legora skew enterprise license, often $1-5M annually for large firms. Per-matter pricing exists for EvenUp-style demand-letter automation, where ROI ties cleanly to settlement velocity.
