Spellbook is an AI contract review and drafting tool that works inside Microsoft Word, with saved playbooks and a multi document agent called Associate. It suits transactional lawyers and in house teams who review contracts all day. It is worth trying with the 7 day free trial, but prices are custom, and it does not cover legal research or litigation work.
What Spellbook is
Spellbook is legal AI built for contracts. Its main product is a Microsoft Word add in that reviews, drafts and compares contracts where lawyers already work Spellbook pricing ↗ Spellbook ↗. Spellbook says it uses GPT-5, Claude and other large language models Spellbook ↗.
The Spellbook Suite includes the Word add in and Associate, an agent for work that spans several documents Spellbook pricing ↗. A newer product, Autonomous Contract Management, aims to run contracts end to end from intake to repository and is in early access Spellbook ↗.
Spellbook says more than 5,000 legal teams use it, including in house teams at Dropbox, Asics and Panasonic and law firms such as Kennedys and McInnes Cooper Spellbook pricing ↗ Spellbook ↗. Hands on testing is in progress, and we will update this review with results.
What it does well
It works inside Word. Review redlines a contract, flags risks and tracks every suggestion, so you can accept or reject changes as you would with a colleague Spellbook ↗. Spellbook also lists connections to Google Docs, OneDrive, SharePoint, Google Drive, Dropbox, iManage and Slack Spellbook ↗.
It drafts from your own material. Draft can write from scratch or from your saved clause libraries Spellbook ↗. Compare checks a contract against industry standards so you can see what is unusual Spellbook ↗. Ask gives quick answers to questions about a document Spellbook ↗.
Playbooks make review consistent. You can turn your team's standards into checklists that are applied on every review Spellbook ↗. For in house teams, Spellbook offers a playbook build service Spellbook pricing ↗.
Associate handles bigger matters. It runs workflows across several documents, which helps on deals with many related agreements Spellbook pricing ↗ Spellbook ↗.
Security is strong. Spellbook says it has zero data retention agreements, so model providers do not learn from, train on or store customer data Spellbook pricing ↗ Spellbook ↗. It lists SOC 2 Type II, GDPR and CCPA compliance on its pricing page, and HIPAA and EU AI Act on its home page, plus SSO, MFA and encryption Spellbook pricing ↗ Spellbook ↗.
Spellbook reports customer results such as 75 percent time saved on contract work, though these are its own claims Spellbook ↗.
Where it falls short
Prices are not published. Pricing is custom and depends on how many people are on your license, so you need to book a demo or start a trial and talk to sales Spellbook pricing ↗.
It is focused on contracts. It does not do case law research, discovery or general litigation drafting, so litigators will need another tool Spellbook ↗.
It needs Word for the core experience. The main product is a Word add in, and Spellbook does not clearly describe a standalone web editor Spellbook ↗.
As with any legal AI, you still need to check its output. Treat its redlines and drafts as a first pass that a lawyer reviews.
Pricing and plans
Spellbook does not list prices or per seat rates. Pricing is custom and based on the number of team members on a license Spellbook pricing ↗.
There are two packages by audience Spellbook pricing ↗. The law firm package includes the Spellbook Suite, group training, online support and dedicated support for teams over 10 Spellbook pricing ↗.

Legal teams can try it free for 7 days, and larger organizations may get an extended trial Spellbook pricing ↗. Spellbook does not say whether a card is needed. There is no free plan, though Spellbook offers free access to academic institutions Spellbook pricing ↗.
