FAQ
Questions, answered
Which videos work?
Public YouTube videos that have captions or subtitles. TeacherGPT builds questions from the video's transcript. Other video sites aren't supported yet.
Do I need an account?
No. You can create and take quizzes in ChatGPT without one. A free TeacherGPT account (just your email, no password) lets you keep lessons in My Lessons, own them, and edit them with AI.
Who owns a lesson, and who can edit it?
The first signed-in person to open a lesson link becomes its owner. The owner chooses what happens when someone else edits it: either they edit the original, or they make their own copy (the default).
Anyone with the link can still take the quiz. Editing always requires signing in.
How are open answers checked?
When a lesson is created, TeacherGPT also writes the key ideas a good answer should contain. When a learner answers, we compare their answer with those key ideas using a fast AI check, and show whether it's correct, partly right, or not quite, along with a model answer.
Short answers are checked instantly in your browser first, with allowance for small typos. If automatic checking is ever unavailable, learners compare their answer with the model answer themselves.
Who can see my lessons?
Lessons are unlisted: they aren't searchable or listed publicly, but anyone with the link can open them. Only share links with people you want to see the lesson.
How do I delete a lesson or my account?
Ask TeacherGPT in ChatGPT to delete a lesson using its lesson ID, or contact support. You can delete your TeacherGPT account at any time from My Lessons.
