The honest brief

CoCounsel

Grounds answers in licensed Westlaw and Practical Law content, so cites are verifiable rather than open-web guesses.

  • Research, contract analysis, and drafting
  • Integrates into Microsoft 365 workflows
  • Prompts not used to train models
  • Expensive enterprise pricing
  • Not a standalone product
  • US-centric legal coverage

Luminance

Autopilot redlining against your playbook across 14+ languages — built for high-volume inbound review, not drafting.

  • Fast autopilot redlining
  • Cross-border, multilingual review
  • Pattern-detection risk heatmaps
  • Purpose-built legal models
  • Built for transactional, not litigation
  • Weaker at net-new drafting
  • Enterprise sales and deployment
  • Opaque per-seat pricing
