Why 30 minutes, not 30 seconds
Most AI tools optimise for speed. Stact optimises for accuracy. We use the highest-reasoning models available — not the cheapest or fastest — because contract risk analysis demands precision, not guesswork.
A 100-page contract passes through 314 individual checks across risk transfer, ambiguity, unfair terms, cross-clause interactions, legislative compliance, and omission detection. That takes approximately 30 minutes. We chose depth over speed because a missed clause costs more than half an hour.
