You're making a homework automation tool. It goes against the founding principle of academia to automate it. Of course they're mad.

Your options are to drop out or close shop.

In academia the whole exercise is to make the student do the processing of reading themselves. After all, if skipping to the gist were acceptable, the professor would've just handed out the gist already.

The school's administration would be annoyed by such a tool regardless of who created it, but since it's a student undermining other students' ability to practice academic rigor, they're putting their weight on you.
