LumenDoc turns receipts, bills, medical letters, warranties, contracts and everyday paperwork into a searchable document library. Scan a page, let AI Vision extract the details, track what you spend, and turn important dates into reminders or calendar events. WHY LUMENDOC SCAN PAPERWORK FAST Capture receipts, bills, IDs, school forms, appointments and important letters with your iPhone camera. LumenDoc extracts text, dates, amounts, vendors and document categories so your library is useful from the first scan. ASK YOUR DOCUMENTS Instead of digging through folders, ask questions like: - When is my appointment? - How much did I spend at Coles? - Where is the warranty for my appliance? LumenDoc answers from your own scanned documents and links back to the source. TRACK SPENDING FROM RECEIPTS AND BILLS Receipts, invoices, bills and fines can feed a spending dashboard automatically. See totals, merchants, categories and trends without connecting a bank account. REMINDERS AND CALENDAR INTEGRATION Turn due dates, appointments, renewals and expiries into reminders or calendar events so bills, warranties, appointments and important follow-ups do not get lost. DESIGNED FOR PRIVACY Your scanned page images stay on your device after AI Vision OCR. LumenDoc sends document images to Google Gemini through our private backend only when AI Vision is used for scanning. Library Ask sends relevant OCR text excerpts, not your page images. Your data is not used to train AI models. FREE AND PRO Free includes 5 lifetime AI Vision scans and 15 lifetime Library Ask questions. Free counters do not reset. LumenDoc Pro includes 100 AI Vision scans per subscription cycle, unlimited Library Ask, full spending history and private iCloud backup. After a Pro user's AI Vision quota is used, scanning continues with on-device OCR until the quota resets on the billing anniversary. Subscriptions are managed by Apple through the App Store.
