FAQ

Questions Spellbook Legal AI owners ask.

  • 01

    What types of contracts can Spellbook analyze?

    Spellbook can analyze a wide range of commercial contracts including NDAs, MSAs, SOWs, employment agreements, vendor agreements, customer contracts, licensing agreements, real estate contracts, and more. The AI is trained on thousands of market precedents and can identify risks, non-standard terms, and missing clauses across all common commercial contract types.

  • 02

    How does the market comparison feature work?

    The market comparison feature compares your contract clauses against 2,000+ market precedents to show how your terms compare to market standards. It shows pro-buyer, pro-seller, and market-standard positions for each clause type, helping you understand whether your terms are favorable, aggressive, or in line with market norms.

  • 03

    How do I get a Spellbook API key?

    Visit Spellbook.legal and sign up for an account. Navigate to Settings → Integrations or API Settings in your account dashboard to generate an API key. The key gives you access to contract analysis, clause drafting, risk detection, and market comparison features. Contact Spellbook support if you need help setting up API access.

  • 04

    Can Spellbook draft custom clauses for specific jurisdictions?

    Yes! When drafting clauses with draft_spellbook_clause, you can specify the jurisdiction (e.g. New York, Delaware, California, UK, EU), party position (pro-buyer, pro-seller, neutral), and custom instructions. The AI generates clauses tailored to the specified jurisdiction's legal requirements and your preferred negotiating position.
