Overview
Spellbook develops AI-assisted contracting and legal drafting integrated with existing workflows.
What Spellbook does
Spellbook provides AI contract review and drafting for in-house legal teams and law firms. Lawyers use it to identify risks, prepare redlines, draft clauses and agreements, and apply consistent positions during negotiation.
Playbooks encode the team’s standards, Compare examines terms against reference positions, and Ask supports questions about the agreement. Associate extends the workflow across multiple documents, while drafting can draw on saved libraries and precedent.
The company is also introducing Autonomous Contract Management, presented as an early-access system connecting intake with end-to-end contract work. Its established review and drafting suite remains centered on the lawyer’s contract workflow, with suggested changes reviewed in context.
