TREATOOL is a Drupal 7 feature set that allows researchers to share digitized texts. Images of the text are made available with the transcription next to it. Users can be given access to the site where they additionally can add notes while they are reviewing the texts.

The tool was firstly developed by CASIT Web Services at the University of Oregon for Heidi Kaufman of the English Department.
