What is Spellbook?
Spellbook is positioning itself as the AI solution for legal contract work, with over 4,000 legal teams already signed up. They just secured a massive $50M Series B in October 2025, led by Keith Rabois, which signals serious investor confidence in the legal AI space.
The platform focuses specifically on contract generation and review - not trying to be everything to everyone like some legal AI tools. But here's the reality check: even Spellbook admits their contract drafting capabilities are still "a work in progress." That's refreshingly honest, but tells you where they really stand versus the marketing hype.
This is enterprise-grade software with custom pricing, which means you're looking at significant investment. Given the mixed user sentiment and evolving capabilities, you'll want to thoroughly test this before committing your firm's budget.
