Automatic Accentuator for Modern Greek 

This tool accentuates automatically unaccented Modern Greek text (vowels without acute accent and diaeresis). You will be able to resolve ambiguous accentuations interactively by clicking on highlighted words. When you are done, you can click on Copy to Clipboard and then you can paste anywhere you want. If your text has other issues like erroneous capitalization and multiple spaces, process the text here first.
