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. Cancel any time in iOS Settings.

Really useful for students! ### 5/5 — Great for keeping track of receipts *2026-02-26* I use this app to scan all of my receipts. It’s so easy to use. I love that. I can just ask it questions like “ how much did I spend at at Woolworths last month?” and it gives me an answer straight away. no more digging through piles of paper trying to remember things. Really happy with it! ### 5/5 — Great for Scanning and Making PDFs *2026-02-24, version 1.0* Very easy to scan contracts and other documents to convert to PDFs, which I can then email and share. Every scanner app does this, but what I love about this one is that I can actually ask questions about my contracts and the AI will answer them. I also really appreciate that it's private. ### 5/5 — Great App for Scanning and Finding Information *2026-02-24, version 1.0* Love this app! I've been scanning my medications and doctor's appointments, as I always forget my med details and appointment dates. The AI helps me keep track of everything. I can ask things like "What time is my appointment with my doctor?" and it answers. It's been so helpful as I'm getting older and used to constantly bug my kids about my appointment and medications. Now I just bug the AI instead. ### 5/5 — Well worth the subscription *2026-02-22, version 1.0* I was using Adobe's scanner app but the cost was too high. LumenDoc's AI is just as good, if not better. Taking pictures of personal files, business cards, and more is easy and fast and everything becomes searchable with AI. It even summarises groups of documents. The coolest feature is that when it provides search results, it also links back to the original document. Well worth the subscription! ### 5/5 — PDF export and Chatbot *2026-02-21, version 1.0* I was paying for Genius Scan. This is much better value. I can still export my scans as PDFs, and I can use a chatbot to find documents and extract information from them. ### 5/5 — Go to for scan and AI *2026-02-21, version 1.0* Been using the app for a couple of weeks and it’s my new go to app for scanning receipts, documents and whiteboard notes. Highly recommend for quickly finding info about the scanned document using the built in ai. ### 5/5 — My own chatbot *2026-02-07, version 1.0* Wish the O365 let me search my documents with a chatbot like this. So cool that my school work is searchable and easy to find! ## Frequently asked questions about LumenDoc ### What can LumenDoc scan?
