- Bruce Robertson has created "Rigaudon", "a complete suite of scripts, python code and data required for producing polytonic Greek OCR"
- A number of people have produced training files for specific Greek fonts in the Kraken OCR engine:
- The Gamera toolkit for analysing and scanning complex texts includes some experiments with polytonic Greek
- Federico Boschetti did some earlier experimentation with adapting/training Google's OCR engine tesseract to ancient Greek texts: http://www.himeros.eu/ (related paper)
- ABBYY FineReader can be made to work with ancient Greek with extensive training
- Google Docs now allows you to have it do OCR on uploaded documents in a variety of languages, and you can get some results by specifying "Greek" and uploading a PDF (images seem not to work). Quality is about on the level of Google Books OCR of printed ancient Greek.
