Your PDF library, only smarter. PDF Inbox gathers the PDFs on your iPhone — invoices, contracts, payslips, manuals, receipts — and organises them for you. No folders to create, nothing to rename. And it all happens on your device. No account, no cloud and no external AI. IT ORGANISES ITSELF Each document is read on your iPhone and filed under its category: invoices, contracts, bank, receipts, payslips, insurance, health, travel, official documents, taxes, manuals, studies, work, personal and other. If it gets one wrong, correct it once and it learns. The next invoice from that same company goes straight to the right place, and you can see exactly what it has learned and delete it whenever you like. IT READS WHAT'S INSIDE From every invoice it picks out the total, the date, the IBAN and who issued it. It also finds policy, contract and customer numbers, booking references and number plates, and links the documents that share them: the insurance policy with its receipt, the car inspection with the garage quote. And it suggests a name you can understand at a glance: 2026-09-18_Endesa_Invoice_61.15.pdf instead of IMG_20260918_0032.pdf. Scanned PDFs too: text recognition uses the system's own engine, without sending a single image anywhere. A SEARCH THAT UNDERSTANDS YOU Type it the way you would say it: "Amazon invoices from this year", "receipts over 100 euros", "insurance March 2025". PDF Inbox turns the phrase into filters — category, company, year, month, amount — and shows them as tags you can remove with one tap. It searches inside the documents, not just their names: type "tenant" and the lease shows up even if the file is called "doc3.pdf". It shrugs off accents, plurals and small typos, knows that "salary" means your payslips, and understands English, Spanish, French, German and Italian. And when nothing matches every word, it says so and shows the closest results instead of an empty screen. HOW YOUR DOCUMENTS GET IN · From the Files app, one or several at a time · A whole folder in one go · From any other app, with "Open in PDF Inbox" YOUR DOCUMENTS STAY HERE Your documents never leave your device. They are not uploaded anywhere, there is no account or sign-up, and no external AI ever sees them. You don't have to take our word for it: the app works just the same in airplane mode. What does go online has nothing to do with your documents. PDF Inbox is free and shows ads from Google AdMob, and iOS asks for your permission before they can use your device's advertising identifier. The app also checks for updates when it opens. Neither ever receives your files or anything inside them. It is all explained in the privacy policy. The original files are never modified or deleted: PDF Inbox always works on its own copy. ALSO · Fast PDF viewer with zoom and page counter · Favourites, plus filters by year and by company · Sort by relevance, date, size or name · Light and dark mode · In English and Spanish; reads documents in five languages · Works offline
