Pricing

Pricing model: Contact sales

No public price on the pricing page: Spellbook says pricing is set by the number of team members on a license and quotes it after a demo. A 7-day free trial is open to individual lawyers, with longer trials offered to larger organisations and free access for law schools.

Overview

About Spellbook

Spellbook drafts and redlines agreements from inside Microsoft Word, suggesting clause language and flagging terms that are missing or one-sided. It benchmarks a draft against market norms and against a firm's own precedent and playbooks. An agent product, Associate, extends the same review across a set of documents at once.

Editorial verdict

Pros & cons of Spellbook

medium confidence

Spellbook wins on the thing that decides legal-tech adoption: it lives in Word, where the lawyers already are, instead of asking them to move. The cost of that is a sales process and a price you cannot check before you engage.

Pros

Native Word add-in means near-zero behaviour change for the people who have to use it
Benchmarks against both market norms and the firm's own precedent, not just generic templates
Well capitalised: $50M Series B led by Khosla in October 2025 plus $40M debt in March 2026
7-day free trial is available without going through procurement

Cons

No published pricing at any tier, so budgeting requires a sales conversation
No API, which blocks integration into an existing contract lifecycle system
Priced per seat, so cost scales with headcount rather than contract volume
The vendor is now actively acquiring competitors, so the product surface may shift

Best for

Small and mid-size firms and in-house teams doing high contract volume in Word
Practices with an existing precedent bank worth benchmarking drafts against
Teams that want redlining suggestions in the document rather than in a separate portal

Not for

Solo practitioners or anyone who needs to see a price before booking a call
Workflows built on Google Docs or a contract lifecycle platform instead of Word
Buyers needing API integration into a CLM, which is not offered

Watch out: Spellbook raised $40M in debt in March 2026 explicitly to buy competitors in a consolidating legal-AI market. If you are evaluating one of its rivals in parallel, factor in that it may be acquired and folded in.
