Startup Idea: Play Script Error Tracking Software

Startup idea to develop a script error tracking software. The software should allow stage managers to upload scripts, highlight lines that are messed up and tag the errors using a dropdown menu. Includes sharing capabilities for actors to track their mistakes.

I work in theatre as a stage manager. One of my jobs is to write down every single time an actor messes up a line, even a little bit. I would love to be able to upload a script, highlight lines when they are messed up, and have a dropdown that explains how they were messed up (skipped, words out of order, etc.). This would need to be shareable so the actors could see it each day. I would pay for this, and I think many theatres would. This is one of the most tedious and time-consuming parts of the job, and the time would be better used in other ways.
