SimpleTCT is a textual analysis tool for making thematic annotations developed by OpenDAHT, Open Digital Arts & Humanities Tools. Collections of text files can be opened and viewed within the application, themes can be defined and given unique color coding. The user can then highlight passages in the texts, assign themes to those passages and write notes associated with those passages. These themes and notes can then be exported to nice concise and simple Word document (.rtf) containing all the selected passages, organized thematically, alongside the relevant notes.
Although lacking a search tool which would be very useful in finding passages to associate with themes, SimpleTCT would be a useful tool and satisfies a need that I have had in past projects. The software runs on Windows, Mac, and Linux using the Java runtime environment, but can be a bit confusing to get set up and running. Contact the ETC (etc@) for assistance.
A video demo of the software can be found on the SimpleTCT website:
