The honest brief
Robin AI
Works inside Microsoft Word and runs natural-language search across your entire contract repository, not just one document at a time.
- Extracts terms and flags contract risks
- Built on Claude with proprietary data
- Drafting, review, and negotiation in one
- Used by large enterprises and banks
- Enterprise pricing; not for individuals
- Narrow scope (contracts)
- Less suited to litigation or legal research
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
