Private, on-device document intelligence

Every document, understood.
Everything stays on your phone.

Scan a receipt, an ID, a policy, a bill. Catadoc reads it right on your phone and turns it into facts you can search, copy, and share. No renaming files, no folders, no cloud.

100% on-device No account needed Works in airplane mode

Scan it, or import it

Point the camera at paper, or pull in the photos of documents already on your phone.

It's understood in seconds

Type, title, people, amounts, and dates, laid out as a profile instead of a filename.

Ask for it like a person

"Bills under 2000." "Passport expiring soon." Your words become filters, and the filters become answers.

Understand

A profile, not a PDF.

The scan is the source. The profile is the point. Open any document and the facts are already waiting, each one a tap away from your clipboard:

  • Who and what: person, merchant, document type, a title that writes itself
  • The numbers: amounts, document & invoice numbers, IDs
  • The dates: issued, due, expiry, birth
  • In your languages: English, German, and Hindi documents, plus passports and IDs from many countries

Find

Search the way you speak.

No filenames to remember, no folders to dig through. Ask the way you'd ask a person: your words turn into visible filters you can keep, combine, and clear. Every suggestion comes from your own library, so every tap finds something.

Organizes itself

Collections you never made.

IDs, Insurance, Receipts & Bills, Medical, Travel, Tax. Documents sort themselves the moment they're understood, then group again by what matters inside each collection: receipts by merchant, IDs by family member.

  • Zero upkeep: no folders to create, no filing chores
  • Expiry radar: IDs and policies surface before they lapse
  • Favourites & archive: pin what you use, tuck away what's done

Share

One PDF, exactly the size they demand.

Embassy portals, landlords, HR, visa agents: they all want one PDF under a size limit. People solve this today by uploading their IDs to random "merge PDF online" sites. Never again:

  • Pick any documents. They become one PDF, in the order you tapped
  • Pick the limit. Email at 10 MB, Portal at 2 MB, or any custom cap
  • Honest compression. A warning before quality visibly drops
  • Fully offline. Your IDs never touch a stranger's server

And the everyday things

Small features you'll use daily.

One-tap copy

Long-press any document and its top facts are ready to paste: passport number, invoice number, amount.

Favourites on top

The documents you reach for weekly stay pinned first, always one thumb-length away.

Expiry warnings

Anything with an expiry date, from passports to policies, surfaces on the home screen 60 days before it lapses.

Scan-quality guardian

A blurry scan gets flagged the moment it lands, so you can retake it while the paper is still in your hand.

App lock

Face ID or fingerprint before anyone sees your library. It holds your IDs, after all.

Multi-page documents

Contracts and statements stay together. Scan page after page into a single document and share it as one PDF.

Protect

Privacy you don't have to take on faith.

Most scanner apps send your documents to their cloud to "understand" them. Catadoc was built the other way around: understanding runs on your phone, so your documents never need to travel at all.

Your documents can't be uploaded

Understanding, search, and storage never touch the network. The app makes exactly one kind of network request: the feedback you write and choose to send. Nothing else, ever.

Encrypted at rest

Your library is an encrypted database keyed from the phone's secure keychain. Lose the phone, not the secrets.

No account, no telemetry

Nothing to sign up for, nothing phoning home, nothing to leak. Delete the app and everything is gone.

Where it earns its keep

Built for real paperwork moments.

Visa run

Passport + bank letter + insurance, one PDF, under the portal's 2 MB cap. No sketchy merge site involved.

Tax season

Every invoice already titled, totalled, and findable by "invoices from 2025" when your accountant asks.

Family IDs

Everyone's documents in one place, grouped by person, with expiry warnings before renewal panic.

Warranty & returns

The receipt from 14 months ago, found by store name instead of scrolling your camera roll.

Private beta

Your paperwork has been waiting for this.

Catadoc is in private beta: Android today, iPhone on TestFlight next. Ask for an invite and start with whatever document is nearest to you.
