The honest take

โœ“ What works

  • Backed by Thomson Reuters โ€” stable, well-funded, long-term
  • Westlaw integration is genuinely unbeatable for legal research
  • Affordable for solo lawyers ($200/mo vs Harvey's $1K+)
  • CoCounsel has years of case law data to learn from

โœ— What doesn't

  • Less polished UI than Harvey (Thomson Reuters UI is dated)
  • Smaller knowledge base feature set than Harvey Vault
  • Slower release cadence than the Harvey team

Verdict

Casetext (CoCounsel) is a strong choice for solo lawyers. The $200/mo pricing is fair for what it delivers.
