From the developer:
Transcelerator is a Paratext plugin that facilitates translation of comprehension checking questions in order to prepare to test the quality and clarity of the vernacular Scripture translation. It helps to semi-automate the process of translating the questions by taking advantage of the previous work done in assigning vernacular equivalents for biblical terms (especially proper names).
