Case study
CourseOS AI course builder for creators

(01)The problem, in their words
I had forty videos and an audience, but turning that into a course meant weeks in Notion, a separate checkout tool, and manually writing quiz questions. I wanted to sell by the weekend, not next quarter.

- Full creator platform: Stripe checkout, certificates, custom domains, creator payouts, and student progress tracking.
