What is Whirlpool?
Atlas indexes the universities. Whirlpool is the other half of free learning: the independent educators and open academies — people like Sal Khan, Grant Sanderson, Josh Starmer, and Shaun Pelling — who built world-class course libraries on their own channels, outside any institution.
Every course here streams from the creator's official channel, with the real curriculum, real progress tracking, and zero interruptions. No account to make, no trial to start, no "upgrade to continue." The way free education should feel.
Right now that's 119 courses and 1500+ hours of teaching across 13 educators — and the catalog keeps growing.
Everything plays, instantly
The same streaming engine as Atlas: real lesson lists, resume where you left off, watched tracking, and one-click downloads — all running locally in your browser.
Creators keep the credit
Whirlpool indexes and streams — it never re-hosts. Every view goes to the creator's official channel, every download link points to their own pages.
No login. Anywhere.
Nothing here needs an account — not watching, not downloading, not saving. Your progress and bookmarks live in your browser, not in a database.
