Cerna

The important stuff hides on your phone. A contract you signed once. A receipt you'll need at tax time. Your insurance card. An API key you pasted into a note and forgot about. It's all in there — buried in Files, in Downloads, in screenshots — right up until the moment you actually need it. Cerna finds it. Point Cerna at a folder and it surfaces what matters — receipts, invoices, IDs, insurance, contracts, statements, tax forms — sorted, with the noise kept out of your way. New documents get caught as they arrive. And every bit of it happens on your device. WHY CERNA IS DIFFERENT On-device. Nothing you scan ever leaves your phone. No account, no cloud, no server that can leak. Deterministic, not a black box. Cerna recognizes documents by their patterns — it doesn't ship your private files off to someone's AI to guess. That means it works on every iPhone, offline, on a plane. Pay once. $5.99, one time. No subscription — because there's no server to pay for. WHAT IT DOES • Surfaces the important documents you forgot you had • Sorts them automatically — receipts, invoices, IDs, insurance, contracts, tax, statements • Search everything by what's inside it, not just the filename — and from your Home Screen via Spotlight • Catches new documents from the share sheet — stop printing it, share it to Cerna • Reads business cards straight into Contacts • Finds exposed secrets — API keys and passwords sitting in plaintext — and routes them to the Keychain, never to a model • Reminds you before things expire — insurance, licenses, renewals • Exports receipts and invoices to a spreadsheet for taxes and reimbursement • Tidies up: duplicates, stale downloads, and your biggest files Built for people who run things from their phone — and are done paying monthly for the privilege. One price. No subscription. Runs entirely on your device.
