The honest brief

Ivo

Redlines contracts directly in Microsoft Word against your own playbooks — a workflow legal teams at Uber, Shopify and Reddit run at enterprise scale.

  • Playbook-driven, customizable reviews
  • AI research agent over your contracts
  • Bulk analysis across contract libraries
  • Doesn't train models on customer data
  • No public pricing — demo-led sales
  • Aimed at in-house teams, not solo use

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
