Hey, I appreciate your views (both positive and negative). There actually is a bit of a back story behind it all. I spent a month working on a different version of rebrain, (still available here: https://dev.rebrain.gg). After putting that work in I started to show it to some friends. It was clear from how they responded that it was not as promising as I had hoped. I listened to their feedback and came up with a different idea for LLM-based education (which is the version that's live now). I did vibe code it in about 3/4 days. But I vowed to try to get feedback sooner rather than later, which is why I posted it on ShowHN pretty early in its development. I do want to improve it... so please let me know if there are things which really frustrate you.

Do you have any info on areas it was broken?

Thanks very much for the feedback. If you have any ideas of how to communicate the retention mechanisms please let me know. If you want to discuss further, please leave feedback on the site (you can do this if you're signed in) and mention you are nivcmo from hn and I'll be in touch via email.

You are right, I'll take out some of the worst colours

They seem all over the place. Instead of specific colours, you could go around the hue circle without touching saturation: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/V...

Thanks for the interesting idea

Haha, thanks for the further education!

I launched https://rebrain.gg/ a few days ago.

It's a bit like Reddit but focused on learning. (Doom learning instead of doom scrolling)

You 1) upload a source 2) direct the kind of questions you want to be asked 3) start answering (and if you get the answers wrong, you can discuss the problem with "AI").

You can read other people's sources, questions, answers and their discussions with AI too.

And if you're learning the same thing as other people, you can join communities to share sources/questions.

It's still very early on, so I'm very interested in any feedback.

Haha -> but has the way you typed changed?/Any new phrases?

I don't write code much anymore.

How would one make a true shell in a website like this one? (As in, is there an open source library to host an interactive shell for educational purposes - eg codecademy)

I couldn't tell you the exact details (I'm only passingly familiar with how it works myself), but you'd almost certainly want to start by looking into web assembly.

I found a-Shell's documentation[1] quite interesting, it describes their use of web assembly and offers some practical tips for compiling stuff so it can work in a sandboxed environment.

I was looking for the same thing too
