ProofKit — press kit

In one line

ProofKit checks whether AI-cited court cases exist in open databases (US, UK, EU, ECHR) and returns a receipt signed with Ed25519 that anyone can verify offline.

Facts

  • Sources: CourtListener, UK Find Case Law, EUR-Lex, HUDOC.
  • Receipt: Ed25519 signature + public hash chain; public key at /.well-known/proofkit-pubkey.
  • Privacy: text processed in memory, only a SHA-256 hash is kept.
  • Prices: Free, Pro $49/month, Team, API $0.02 per citation — see /pricing.
  • Open research record: doi:10.5281/zenodo.22848827.
  • Public test so far: 5/5 real cases verified, 3/3 fabricated caught — a small sample; a larger open benchmark is in preparation.

What ProofKit does not do

  • It does not check whether a case supports an argument.
  • It does not replace Westlaw, Lexis or a lawyer.
  • Israeli decisions are not covered yet.
  • No SOC 2 certification.
