What our research says

AI Judge

A free curiosity: type both sides of an argument, pick a jurisdiction, get a written opinion. Useful for a second perspective on a roommate or freelance-invoice disagreement, and nothing more - there is no firm, no bar admission and no named operator behind it. The jurisdiction picker suggests more legal grounding than a language model can actually deliver.

Pros

  • Fully free with no account, card or sign-up wall
  • Supports multiple parties, not just two, with an add-contender control
  • Jurisdiction, dispute type, formality, length and mediation mode are all configurable
  • Mediation mode reframes the output toward reconciliation instead of a winner

Cons

  • No company, contact address or country disclosed anywhere on the site
  • Output has zero legal standing and no lawyer reviews it
  • Jurisdiction selection implies statute-level grounding that is not evidenced

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

Choose Spellbook if you need
