Problem
Contract review meant lawyers reading 50-page contracts line by line in Microsoft Word to find issues, then manually editing and copying between agreements. A single agreement could absorb 10 hours of a lawyer's time, making it a $10,000 document at a top firm's billing rate, and in-house legal teams see thousands of contracts flow through every year.
…Before large language models, contract work meant reading every line by hand.

Solution
Spellbook built Claude-powered agents that draft and review contracts inside Microsoft Word, comparing terms against the market and applying each legal team's own codified review standards (playbooks) automatically. About 15 Claude agent configurations are orchestrated on the review surface alone, matched to subtask complexity, with Fable 5 used as an oracle model to generate evaluation criteria and grade production models. The product keeps edits confined to specified paragraphs with zero data retention, and Spellbook recently launched autonomous contract management that moves agreements through triage, review, negotiation, storage and monitoring without a human opening them first.
