The honest brief
Definely
Goes deep on the unglamorous drafting work — definitions, cross-references, proofing — inside Word rather than bolting a chat panel onto legal review.
- Native Microsoft Word workflow
- Used by 150+ law firms
- iManage + NetDocuments integrations
- SOC 2 and ISO 27001 certified
- No public pricing — demo first
- Tied to the Word workflow
- Focused on pre-execution drafting
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
