The honest brief

Harvey

The default general-purpose legal AI at scale: Vault analyzes up to ~100K-doc collections, used across AmLaw 100 firms.

  • Adopted by most AmLaw 100 firms
  • Bulk doc analysis via Vault
  • Grounds answers in firm's own materials
  • Operates across 60 countries
  • No public pricing, sales-only
  • ~$1,000+/lawyer/mo, 20-seat minimum
  • Tuned to big-firm billable workflows
  • Heavy enterprise onboarding

Spellbook

Runs entirely as a Microsoft Word add-in, so drafting and redlining happen in the document lawyers already work in.

  • Native Microsoft Word add-in
  • Clause benchmarking + playbook review
  • Early generative-AI legal tool (2022)
  • Multi-model (GPT, Claude)
  • Paid-only, no free tier
  • Tied to the Word workflow
  • Less suited to litigation/research
