## In brief
Spellbook is a Microsoft Word add-in for AI-assisted contract work that provides clarity analyses, risk flags, clause suggestions, and contract summaries in plain language directly in the familiar Word interface.

Law firms and legal teams benefit from team access with role management; client-related data is not stored on Spellbook servers, allowing use even for confidential contract work.


## Limits
Spellbook no longer publishes fixed seat prices, prompt limits, document quantities, or agent runs. Pricing is scoped by team size. The seven-day trial is the only freely quantified access. Spellbook assists contract work but does not replace legal review and should be used by appropriately qualified professionals.
