ClauseCheck helps you read contracts with confidence. Scan any agreement, get plain-English summaries, and see every flag pinned to the exact words in YOUR document โ€” before you sign. READS PAPER, PRIVATELY Photograph a lease, job offer, NDA, freelance agreement, insurance policy, or any contract. On-device OCR reads it right on your phone โ€” the image never leaves your device. Only the extracted text is sent for analysis, with your explicit consent. WON'T LIE ABOUT WHAT'S IN YOUR CONTRACT Every flag is pinned to the exact verbatim quote from your document via offset span-verification. If we can't locate a clause word-for-word, we drop it. ClauseCheck structurally cannot invent a clause that isn't there. REMEMBERS YOUR DEADLINES Save documents to your vault and get reminded before renewal dates, notice deadlines, and expiry windows. You confirm every date before we schedule anything. FREE TO START Three full analyses, free. Each one shows the plain-English summary, the attention score, how many clauses were flagged, and your most important flag pinned to its exact words โ€” plus one deadline reminder, and viewing and exporting everything you have saved, always. PRO Unlimited analyses, every clause flag rather than just the top one, common-pattern context on clauses, and unlimited reminders. $9.99/month or $49.99/year, each with a 7-day free trial. Cancel anytime in Settings. ClauseCheck provides informational analysis only. It is not legal advice and is not a substitute for a licensed attorney.
