Spellbook is an AI tool built to automate contract drafting, review, and negotiation for legal professionals. It targets transactional lawyers, in-house legal departments, and law firms. The software works as an AI copilot inside existing document workflows.
The platform addresses time-consuming manual contract tasks. These include spotting hidden financial risks, catching drafting errors, and writing repetitive boilerplate language. Spellbook states it can help teams complete routine contract reviews up to 10 times faster.
Spellbook runs as a native sidebar add-in inside Microsoft Word. Users do not need to leave Word or copy sensitive text into another application. When a document opens, the tool detects contract type, jurisdiction, involved parties, and writing style automatically.
Key differentiators include the Word-native design, a companion tool called Spellbook Associate for multi-document work, and an upcoming Autonomous Contract Management system. Spellbook also offers Zero Data Retention agreements so customer data is not used to train public AI models.
Pricing
Spellbook does not list a permanent free plan for standard business use, though academic institutions can request free access. A 7-day free trial is available for lawyers and legal teams, with extended trials possible for larger corporate evaluations. Paid plans use a seat-based model, with pricing determined by the number of team members on a license. No fixed public prices are listed, so interested teams must book a sales demo for a custom quote.

Use Cases
Automated Third-Party Contract Review
An in-house attorney reviews an unfamiliar vendor agreement for hidden risks. Spellbook scans the document and inserts tracked-change redlines favoring the user’s position.
Enforcing Corporate Negotiation Standards
A legal department wants consistent fallback language across junior associates. Custom Playbooks run automatically against incoming files to check compliance and flag missing terms.
Inline Legal Clause Generation
A lawyer needs a jurisdiction-specific clause added to an active agreement. Spellbook drafts a tailored clause based on the document’s existing style and context.
Objective Deal Benchmarking
A negotiator needs data to support a position on a disputed contract term. The Market feature compares the clause against agreements from more than 80 countries.
Matter-Level Due Diligence Workflows
A team analyzing an acquisition needs to compare many contract files at once. Spellbook Associate processes multiple documents together instead of reviewing each file individually in Word.
