kraken

Turn-key OCR engine trained for historical and non-Latin script documents, not modern print.

Desktopfree

Kraken is an open-source, turn-key OCR engine built for historical and non-Latin script material, where mainstream OCR tools tend to fail. It offers fully trainable layout analysis, reading-order detection, and character recognition, with support for right-to-left, bidirectional, and top-to-bottom scripts and output in ALTO, PageXML, and hOCR formats. It's aimed at digital humanities researchers and archivists digitizing historical or multilingual document collections.
