KeepProof — a smart search engine for your paper world. OCR automatically extracts key information from your tickets, so a photo is all it takes to file them with no manual entry. Shopping receipts, invoices, warranty cards, product manuals, eye prescriptions, medical records, registration slips, repair records, parking tickets, coupons, airline tickets, contracts—capture them, save them, and leave the rest to KeepProof. Whatever you scan, you can ask about: • Scanned a supermarket receipt → “How much were the shrimp balls yesterday?” • Scanned a manual → “Find the washing machine manual.” • Scanned a warranty card → “How much longer is the computer under warranty?” • Scanned an eye prescription → “What was my prescription the last time I got glasses?” KeepProof finds the relevant tickets, gives you a clear answer, and lets you open the original document whenever you want to verify it. You’ll like KeepProof because it can: • Make your tickets talk. Search one ticket or your entire collection using everyday language. • Remember important dates for you. Automatically detects warranty, return, expiry, and travel dates; you decide which reminders to enable. • Let Siri find your tickets. On iOS 18+, ask Siri to search your tickets or open the matching document. • Produce proof when it matters. Quickly find what you need for returns, reimbursements, warranties, medical visits, or travel—even offline. • Keep your privacy to yourself. No account, no ads, and no behavior analytics. On supported iPhones (iOS 26+), conversations are handled on-device by Apple Intelligence; you may also choose to connect a supported third-party AI service. It’s not just for tickets. KeepProof also keeps screenshots, electronic invoices, and documents exported from other apps together. Simply ask in natural language to find them and retrieve the key information they contain.
