About
Mail arrives, deadlines pass, and sooner or later it costs money. Duesy fixes that with one photo.
Photograph a letter, an invoice or a contract. Duesy reads the deadline, amount, IBAN, customer number and sender and turns them into one card: what to do, and by when. It reminds you ahead of time, three days before a payment, four weeks before a cancellation deadline, the day before an appointment.
• One photo is enough: camera, Photos, PDF, or share from Mail and Safari
• Recognises invoices, contracts, notice periods, official letters, appointments and warranties
• Every sender detail one tap away: address, phone, email, customer number
• Copy bank details, generate a cancellation letter, add appointments to Calendar
• Home Screen and Lock Screen widgets
• Archive with full-text search, by category or month
• Face ID lock and a complete data export
Privacy: documents and images stay on your iPhone. Analysis runs with Apple Intelligence on the device. Optionally add your own Claude API key; then only the recognised text is sent, never the image.
