Open the catalog and pick the path closest to your work. Every course lists its modules and lessons up front, and lessons marked free preview are labelled so you can sample the teaching first.

Ask in plain English. Vortex matches lessons on their topic and video moments on their chapters and transcripts, ranks the most specific matches first, and links straight to the lesson page starting at the matched second.

No. The catalog, search and every lesson page are open. Signing in saves your progress and quiz results, adds My Learning and personal plans, and lets you post and vote on the Ideas board.

Describe what you want to learn and Vortex designs a syllabus, matching each lesson to a YouTube video through YouTube's official API. Plans are private to you, with progress and a quiz per lesson.

Short articles that go deeper on one idea. Each note is tied to a topic and, where it fits, to the course it belongs to.

Yes. Post it on the Ideas board. The team reviews every submission before it appears publicly, and you can upvote the ideas you want most.

No. Lessons play in YouTube's own player embedded on the lesson page, with the creator credited, so a search result opens the lesson and starts at the right second without sending you elsewhere.
