The best reference isn't a slide deck — it's an application running for real users. Here are ours.

Product 01KaranScanMobile app · iPhone
On the App Store

A document scanner in your pocket. Snap an invoice, contract or receipt and KaranScan crops it, straightens it and, if you like, names it based on what it says. Then sign it with your finger, translate it and send it as a PDF. Your documents stay on your phone only — no account, no cloud.

  • Documents stay on your phone — no sign-up, no cloud. Smart features are off until you turn them on; even then only the recognised text is sent, never images or signatures
  • Its own camera finds the edges of the page and takes the shot as soon as you hold still
  • Finds a document by what's inside — a name, an invoice number, a street
  • Names and summaries from the content: copy the amount, due date or account number with one tap
  • Sign with your finger and add your own text to the page
  • Translates the whole document into five languages, including a bilingual PDF
  • Multi-page PDFs, Word export and Face ID lock

Product 02ArchivarDesktop application · Mac, Windows on the way
In development · pilot

A smart database of your documents. Photograph or upload a piece of paper and Archivar reads it, names it and files it in the folder of the party it belongs to — the other parties get a shortcut. It handles any document at all — whatever it is, it works out what it is, pulls out everything that matters and links it to what is already in your archive. The archive and the database are built locally on your own disk.

  • The archive and database stay with you — on your own disk, optionally encrypted with a password. Documents are read by AI (Google Gemini, Anthropic Claude for some features) through our server, which does not store the content; the content is not used to train AI
  • Tells people and companies apart by birth number and company ID — namesakes are never merged
  • The Courier watches a folder and processes new documents on its own
  • Invoices, due dates and payment matching from bank statements
  • Full encrypted backup of archive and database in one file, weekly if you like
  • The app speaks fifteen languages — Czech, English, German, Polish, Slovak, Ukrainian, Hungarian, Spanish, French, Dutch, Italian, Croatian, Danish, Swedish and Norwegian
  • Understands Czech administrative reality (ARES, company IDs, VAT) and pre-fills PDF forms

Product 03TopSprávaWebsite, web app and mobile app · property management
Pilot operation

A complete solution for managing individual rental units and rental portfolios: a public website, a web application for managers, owners and tenants, and a companion iPhone app. It replaces binders, spreadsheets and paper handover protocols with one system where the manager, the owner and the tenant each see exactly what they need.

  • Unit card — leases, tenants, documents and history in one place
  • Water and heat meter readings inside the app
  • Contractors upload invoices through a single-use link, no account needed
  • Paperless unit handover on iPad, including on-screen signature
  • EU data, encrypted backups with verified restores
  • iPhone app — one app for every role; after sign-in it shows only what that role needs
  • On the phone: payments, defect reports with photos, chat with the manager and document scanning for approval (AI suggests the name)
  • For managers: tasks, contacts and field inspections with photos and meter readings that work without a signal
  • Push notifications, app lock with Face ID
