Three tools, free and open source. Each works on its own, on your own machine, without us.

Everything here is published under an open licence, with the code, the trained models and the training data in the open. Install any of them with pip, read the documentation, and use them as you like; nothing phones home and nothing needs an account. If you would rather we did the work, that is what our services are for.

  • Tetrak OCR

    Turns scans of old print into searchable text. It runs several OCR (optical character recognition) engines over each file, keeps the best reading, and sets aside anything it cannot trust for a person to check. Local first: no material leaves your machine unless you send it.

  • Armenian text recognition

    A recogniser we trained ourselves for printed Armenian, Eastern and Western, in either spelling. Installs as an add-on to EasyOCR, or as Tetrak OCR’s Armenian engine, with the model and its training data published alongside.

  • Transliteration and cross-script search

    Detects the script, writes it in Latin letters by a named library standard, and folds every spelling of a name to one form for searching. Armenian, Georgian, Russian and Syriac so far.
