Hey everyone! I really like how websites like Brilliant try to teach in an interactive way. But it’s like $160 (or more depending on the region) a year so I’ve been making a free one.
It’s called OpenAha. right now there’s 140+ courses and 1000+ lessons in math, physics and chemistry. no account or ads.
A few to try if you only have a minute:
- untangle a graph: https://openaha.org/courses/graphs/planar/?step=1
- draw the house in one stroke: https://openaha.org/courses/graphs/konigsberg/?step=3
- program a little robot: https://openaha.org/courses/coding/sequence/?step=6
- Two pendulums passing energy back and forth: https://openaha.org/courses/waves/coupled/?step=3
This project is mostly implemented with claude: I planned every course, then wrote the lessons with AI. so far only about one third of the pages have been carefully reviewed by a person. That’s why I’d really like people to poke at it. If a lesson is confusing or sth’s wrong, make a PR or hit the flag button in the lessons. Also feel free to contribute on github to make this even better.

Edit, to clear something up: OpenAha isn’t affiliated with Brilliant and doesn’t use any of their content. I don’t even have a Brilliant account. Brilliant just uses the style of learning I liked (try things first, explanation after). every lesson was written for this project, and we’re improving it as an open source community.
And yes it’s not finished, there will be mistakes. That’s what the flag button on every step is for, every report gets fixed in public on github
This post is a perfect embodiment of the discourse over AI happening everywhere. AI? Must be slop. AI? Just a tool bro, judge the result. Throw opensource in the mix, just needs popcorn. My two cents, the initiative is laudable, there’s not enough quality free and open source education materials out there, Gcompris for younger kids is good but gets exhausted quickly with age. Now the quality is the question mark when you use a black box like AI, and not talking about copyright that these tools piss on, ironic when producing open source… Obviously you put a lot of effort in it, it has the merit to exist vs the huge effort to create an open source community involved enough in an education project. It’s my two cents, I’m not concluding on anything.
There are textbooks you can grab on shadow libraries and recorded lectures on youtube (though exceptionally hard to find). Edtech is all crap, frankly. It’s even more crap when it’s AI-generated. The best way to learn a subject is still the way people have been doing so for hundreds of years.
