The honest brief

Ironclad

Deeper lifecycle coverage than point review tools — Jurist redlines against your playbooks inside the same platform that runs intake, workflow, and storage.

  • Full CLM, not just review
  • Jurist agentic redlining
  • Strong enterprise customer base
  • No-code workflow designer
  • Enterprise pricing ($30K+/year)
  • No published list pricing
  • Implementation takes weeks

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
