Fyle files your paperwork for you. Scan a letter, an invoice or a contract. Fyle reads the text, gives the document a title, writes a short summary and puts it in the right folder. Then just ask, for example: "When can I cancel?" AI FROM APPLE Fyle runs on Apple Intelligence. The model on your iPhone writes the title, summary and tags, picks the folder and answers your questions. The text stays on your device. If a document is too long for it, Fyle analyzes it with Apple's Private Cloud Compute, so it stays with Apple. Fyle uses an online model only when neither works. If you prefer, Fyle works offline only. Apple Intelligence needs a compatible device. On other devices Fyle analyzes documents online. HOW IT WORKS 1. Scan or share: with the camera and automatic edge detection, from Photos and Files, or with Share from any app. 2. Fyle sorts: title, summary, tags and folder are filled in for you. You can change anything, and your choice wins. 3. Find it again: full-text search in Fyle, in Spotlight and with Siri. FOLDERS All your folders are in one place, like Taxes, Insurance or Home. Create new folders, rename them and move several documents at once. ALL OVER YOUR IPHONE - Siri: "Scan with Fyle" - Shortcuts: open documents, search them and get their text - Spotlight: search the full text of your documents - Scan button in Control Center, on the Lock Screen and as a Home Screen widget - Fyle runs on iPhone, iPhone Duo and iPad YOUR DATA - You choose where your PDFs live: in iCloud Drive, in any folder in the Files app, or only on your device. - Protected Words: Fyle blacks out words like your name or your bank account number before any AI sees the text. The list syncs through iCloud. - Fyle needs no account. FYLE PRO Fyle Pro unlocks your library, unlimited scanning, AI chat and the Siri and Shortcuts actions. New subscribers get a free week to try it. I build Fyle on my own in Germany and read every message you send me from the app. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.manuelfessen.de/fyle/privacy
