Spellbook AI features and pricing (October 2026)

Spellbook is an AI contract drafting and review tool that runs inside Microsoft Word, built for transactional lawyers at law firms and in-house legal teams of any size.

Spellbook works as a Word add-in with functions for Review, Draft, Compare against market standards, Ask for legal questions, Associate as a multi-document agent and Playbooks that encode the team's review standards. The vendor says more than 5,000 legal teams use it. Licenses are sold per user, with a 7-day free trial. It suits solo lawyers and small firms as well as larger legal departments, and no separate IT project is needed because users sign in with their Microsoft account.

• Redlines contracts in WordReview reads the open contract, flags risky clauses and proposes redlines directly in the document. Lawyers get a first markup in minutes and focus on the points that need judgment.
• Drafts from templatesDraft writes clauses or whole agreements from scratch or from the team's saved templates. Routine documents take less time, and wording stays close to the firm's own standards.
• Applies the team's playbookPlaybooks store review positions, and the AI applies them to each new contract. Junior lawyers review in line with house standards, and results become more consistent across the team.

• Runs as a Word add-in with Microsoft sign-in, so organizations can enforce multi-factor authentication through their Entra tenant.
• Hosted on AWS in Canada and the US, with zero data retention agreements with OpenAI and Anthropic.

Spellbook runs as a Word add-in worldwide and, according to the vendor, serves legal teams in more than 80 countries, with data held in Canada and the US.

Spellbook stores data in Canada and the US, so EU firms should review the transfer basis and the data processing terms in the trust center. Ask for a quote by team size, since prices are not published. Test during the 7-day trial whether the playbooks match your own templates.
