Overview

Spellbook is a contract AI suite for law firms and in-house legal teams. It helps lawyers review contracts, draft agreements and keep positions consistent across a deal, working mainly inside Microsoft Word. The company says it is used by more than 5,000 legal teams.

Main features

The Spellbook Suite includes a Word add-in with Review, Draft, Ask, Benchmarks and Playbooks. Drafting creates new clauses, full agreements and revisions from AI or from your own precedents. Review lets you redline contracts from your side of the negotiation with every suggestion tracked. Playbooks turn a team's standards into checklists that are enforced on every review, which helps keep positions consistent between lawyers. Associate is described as an AI agent that can work through multi-document legal matters under your oversight.

End-to-end contract management

Spellbook also describes an AI contract management system covering intake, where contracts arrive from email and Slack with a first-pass review against your standards, and a repository where signed contracts are stored, searchable and monitored for renewals and new risks.

Results and security

The site quotes pilot users reporting 55 percent time saved and cites 75 percent time saved on contract work, which are the company's own figures. On privacy, Spellbook says it has zero data retention agreements with its LLM providers, so client data is not used for training.

Pricing

Pricing is quoted rather than listed. Law firm plans include the suite, group training and online support, with dedicated support for teams over ten. In-house plans add a playbook build service. There is a 7-day free trial, and demos can be booked.

Who it suits

Spellbook suits commercial lawyers in firms and in-house teams that handle a steady flow of contracts such as supplier agreements, MSAs and NDAs.

Things to consider

AI suggestions must be reviewed by a qualified lawyer, because a missed clause or an incorrect redline can have serious consequences. Building good playbooks takes time, but it is what makes reviews consistent. Confirm that the security terms meet your professional obligations and client confidentiality requirements, and check jurisdiction coverage if you work across countries. Track accuracy and time saved during the trial with real matters.
