Built for busy people who are tired of digging through PDFs.

Ask LumenDoc

How much did I spend on groceries last month?

Based on your receipts, you spent $847.32 on groceries in December 2025:

Target: $412.50 (4 visits)
Woolworths: $298.82 (3 visits)
Aldi: $136.00 (2 visits)

When does my car rego expire?

Your vehicle registration expires on March 15, 2026. Renewal notice was received on Dec 2.

The old way: scan, PDF, forget

Traditional scanner apps turn paper into static PDFs that disappear into folders. When you finally need something, you end up scrolling, opening, and skimming file after file.

✕ PDFs pile up and you never remember what's inside.
✕ Manually naming files is tedious and inconsistent.
✕ Searching later means digging through folders and filenames.
✕ There's no way to just ask "What did my doctor say last visit?" and get one clear answer.

LumenDoc Way

Scan, AI reads & organizes, Ask, Instant answers

Your personal document AI

LumenDoc turns everything you scan into a searchable, answerable knowledge base that only you control.

Smart scanning

Point your camera at any document-receipts, invoices, medical letters, contracts. LumenDoc reads the text and categorizes it automatically.

Natural language search

Forget filenames and folders. Search by describing what you need: "car registration renewal," "June power bill," or "last physio invoice."

Chat with your documents

Ask plain-English questions across all your scans: "How much have I spent on car maintenance this year?" LumenDoc gives concise answers with links to the sources.

From paper to answers in seconds

Scan

Serious security for your personal life

Your paperwork is private. LumenDoc is designed so it stays that way.

Encrypted by default

All traffic uses HTTPS, and your documents are encrypted at rest on our servers.

No AI training, ever

Your documents and questions are never used to train AI models. LumenDoc uses APIs that explicitly do not learn from your data.

Biometric app lock (coming soon)

Face ID and Touch ID support is on the way, so only you can open LumenDoc on your phone.

Your docs are yours. Not for ads. Not for AI training.
