- LinkSquares: LinkSquares offers an AI-powered contract management and analysis platform, focused on in-house legal teams. It overlaps with Spellbook on contract review, extraction, and post-signature analytics.

Broad incumbents
- Thomson Reuters CoCounsel / Practical Law: Thomson Reuters is a global legal information incumbent (Westlaw, Practical Law) that has launched CoCounsel, a generative AI legal assistant, and is both an investor in Spellbook and a potential platform competitor with bundled content and distribution.
- LexisNexis (Lexis+ AI / Protégé): LexisNexis (RELX) bundles Lexis+ AI and Protégé as generative AI assistants for legal research and drafting. As an incumbent legal-data publisher with deep AmLaw relationships, it competes with Spellbook for budget and workflow share.
- Onit: Onit is an enterprise legal management and CLM platform for corporate legal departments, with AI capabilities including review, workflow, and spend analytics. It overlaps with Spellbook's ACM vision for end-to-end contract and legal-ops automation.
Emerging players
