Your important papers, found again in three seconds. SmartScanner scans your documents, names them, files them and warns you before they expire. No folders to create, no names to type. JUST SCAN Take a photo of a document. The app detects the edges, straightens the page and chains together the pages of the same document. The result is sharp, readable and ready to send. THEY NAME THEMSELVES "Electricity bill February 2026" instead of "IMG_4821". The AI reads the document, understands what it is and gives it a name you'll still understand six months from now. THEY FILE THEMSELVES ID, housing, health, car, work: every document lands in the right folder without you having to decide. And you stay in control: everything can be edited, renamed and moved. YOU'RE WARNED IN TIME ID card, passport, vehicle inspection, insurance: the app spots expiry dates and alerts you before it's too late. FIND ANY DOCUMENT Search doesn't stop at file names: it reads the text INSIDE your documents. An amount, a reference number, the name of an insurer, and the document comes right up. ASK YOUR QUESTIONS "When does my ID card expire?", "How much was my August bill?" The assistant reads your documents and answers. It can also sort, rename and create folders for you. YOUR DOCUMENTS STAY WITH YOU Everything is stored on your iPhone. No account to create, no cloud, no password. Your papers go nowhere, and you can protect your most sensitive folders with Face ID.
