Clment vs Spellbook

Clment

Clment's custom rulebooks and citation-linked risk flags make it more configurable than a generic contract-summarizing tool, and API/SDK parity with the web app means it can slot into an existing document pipeline. The free plan is enough to evaluate it, but the API starts with Pro at $149 a month, a steep first step for a small team.

Pros

• +Rules are user-defined rather than a fixed one-size checklist
• +Outputs a tracked-changes Word document ready for negotiation, not just a summary
• +Full API and SDK parity with the web app, with an OpenAPI spec published

Cons

• −The first paid plan is $149 a month, with no cheaper tier between free and Pro
• −Credit costs for different actions add a layer of complexity to predict monthly spend
• −API, MCP and webhooks are not included on the free plan

Spellbook

Spellbook wins on the thing that decides legal-tech adoption: it lives in Word, where the lawyers already are, instead of asking them to move. The cost of that is a sales process and a price you cannot check before you engage.

Pros

• +Native Word add-in means near-zero behaviour change for the people who have to use it
• +Benchmarks against both market norms and the firm's own precedent, not just generic templates
• +Well capitalised: $50M Series B led by Khosla in October 2025 plus $40M debt in March 2026
• +7-day free trial is available without going through procurement

Cons

• −No published pricing at any tier, so budgeting requires a sales conversation
• −No API, which blocks integration into an existing contract lifecycle system
• −Priced per seat, so cost scales with headcount rather than contract volume
• −The vendor is now actively acquiring competitors, so the product surface may shift
