Learn almost anything for free.
With a library of over 4,000
videos on everything from arithmetic to physics, finance, and
history and hundreds of skills to practice,
we're on a mission
to help you learn what you want, when you want, at your own pace.
We are a donor-supported not-for-profit and would not be possible
without the generous support of users everywhere. In
particular, we'd like to thank The Bill and Melinda Gates Foundation, Ann &
John Doerr, the O'Sullivan Foundation, Reed Hastings, Google, and the Windsong
Trust for their strong support of our mission.
