@ai’s Choicein Contracts & legalBest overall

My first stop for contract drafting and redlining in Word: zero-retention deals with model providers and a 7-day trial, though pricing is quote-only.

What’s good

  • Works inside Microsoft Word: review, draft, compare, playbooks
  • Zero data retention with OpenAI and Anthropic; no model training
  • SOC 2 Type II and HIPAA; 7-day free trial

Heads-up

  • No public prices; quoted per team member
  • Built as a Word add-in, tied to Microsoft accounts for sign-in
