Great for School Work

A great way to scan important readings for reference, along with class notes that the AI can then help summarise. Really useful for students!

Great for keeping track of receipts

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!

Great for Scanning and Making PDFs

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.

Great App for Scanning and Finding Information

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.

Well worth the subscription

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!

FAQ

What can LumenDoc scan?

LumenDoc can scan various documents including receipts, bills, medical letters, warranties, contracts, IDs, school forms, and appointments. The AI Vision feature extracts details like text, dates, amounts, and categories from these scanned pages.

How does LumenDoc's AI work?

LumenDoc uses AI Vision to extract information from scanned documents. For the 'Ask Your Documents' feature, it sends relevant OCR text excerpts to Google Gemini through a private backend, ensuring your document images are not used to train AI models.

What are the limitations of the free version of LumenDoc?

The free version of LumenDoc offers 5 lifetime AI Vision scans and 15 lifetime Library Ask questions. These counters do not reset, meaning you have a fixed number of uses for these features.

What features are included in LumenDoc Pro?

LumenDoc Pro provides 100 AI Vision scans per subscription cycle, unlimited Library Ask questions, full spending history tracking, and private iCloud backup. If the AI Vision quota is exceeded, scanning continues with on-device OCR.

How is my data protected with LumenDoc?

LumenDoc is designed for privacy. Scanned page images remain on your device after OCR. Document images are only sent to Google Gemini when AI Vision is used for scanning, and your data is not used to train AI models.

How do I cancel my LumenDoc Pro subscription?

Subscriptions for LumenDoc Pro are managed by Apple through the App Store. You can cancel your subscription at any time by going to your iOS Settings.

Does LumenDoc have ads?

No, LumenDoc does not have advertisements. The app offers a free tier with limited features and a Pro subscription for enhanced functionality.

What devices is LumenDoc available on?

LumenDoc is available on iPhone, iPad, and iPod. The app is rated for ages 4 and up.
