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
