I built https://rebrain.gg. It's a website which is intended to help you learn new things.
I built it for two reasons:
1. To play around with different ways of interacting with a LLM. Instead of a standard chat conversation, the LLM returns question forms the user can directly interact with (and use to continue the conversation with the LLM).
2. Because I thought it would be cool to have a site dedicated to interactive educational content instead of purely consuming content (which I do too much).
An example of a (useful-for-me) interactive conversation is: https://rebrain.gg/conversations/6. In it I'm learning how to use the `find` bash command. (Who ever knew to exclude a directory from a look-up you need to do `find . -path <path> -exclude -o <what you want to look for>`, where `-o` stands for "otherwise"!)
Still very early on, so interested in and open to any feedback.
Thanks!
One observation: the real challenge with "doom learning" products is retention. People install Duolingo with good intentions, then drop off. Consider adding: - Spaced repetition (show me this again tomorrow, then in 3 days) - Micro-commitments (5-minute sessions, not 30) - Contextual relevance (I just learned 'find' — now quiz me next time I'm actually in a terminal)
The quiz format works well for syntax/commands. For conceptual topics, maybe switch to "explain like I'm 5" mode with the LLM.
Good luck!
There is a reason chat bots work - it mimics natural human interaction.
But this can be interest pattern - for say AI driven personal tutor for math topic
Lastly - for love of god - pls do something with the UI - all colors and bubbles and I am totally lost just trying to make sense of what is going on. Look at reditt if you just want back and forth thread convo style. Life is simpler that way.
wsl find ...
You can run all Linux commands this way. Also, pretty sure that find's "-o" is the Boolean "or", not "otherwise". (Yet another example of why learning from LLMs is dangerous, I suppose).
One potential direction, simple cards that are True/False.
Directed learning towards some goal is always going to be useful. These replacements for doom scrolling are addressing a surface level issue. Just change your habit to be spaced repetition on flash cards.
This is something else entirely and requires far too much thinking for the label.
The very first question is full of obvious bugs.
You have 'find . -name "notes.txt"' selected, it then says 'You submitted: ls -R | grep notes.txt: find . -name "notes.txt"', then it responds:
'Thanks — your answer looks like it was partially entered.
'You picked find . -name "notes.txt" (good choice). The submission shows an escaped/unfinished string: find . -name \. The correct full command is find . -name "notes.txt", which searches recursively from the current directory for files or directories named exactly notes.txt.'
There seems to be some weird kind of quoting issue going on there. I would fix obvious issues like that before sharing this with the world.
> why do you think that this is worth sharing with the world yet?
It's worth sharing because it's cool, even if it's not perfect yet!You'll never make every single person on HN happy. But if you share your stuff early and make one person happy at the very least that means you should keep working on it!
Don't let perfectionism get in the way of good enough :]
Show HNs never pleased everyone, and it'd be silly to try, but until recently there was a bit of a "it's not perfect... but the person has spent more time working on this than I have even spent thinking on the problem" kind of expectation whereas now many of them feel like the comments section ends up doing more thought about the submission than was put into refining it.
It'll be really interesting to see where this settles. In the meantime, erring on the side of kindness tends to work best!
Anyhow, I'm just a bit bitter about the onslaught of obviously vibe coded projects that very little effort has been put into. And OP did ask for feedback. But I shouldn't have been so mean about it. I know it can be fun to be able to whip up something quicker than you could before, but I really wish people would spend a tiny bit more effort on it before asking for feedback.
I am also not a big fan of trying to beat doomscrolling. One of the defining properties of doomscrolling is that it is mindless and addicting. The moment you try to create a mindful, healthy alternative, you've already lost. No product will ever beat doomscrolling, only individuals dedicated to their own mental health are capable of clearing this hurdle.
It would always start to make every correct answer option "C" over time, no matter what I tried. Eventually I was so focused on whether or not it was stuck in a "C" loop that I started overthinking all of the questions and wasting time.
Flash forward to testing Sonnet 4.6 recently to try and see if it could effectively teach me something new, I got about 5 prompts in before I had to point out an oversight, and it gave me the classic "you're absolutely right, ignore that suggestion".
This is anecdotal of course, but at least LLMs are helping to build my skills of fact verification and citation checking!
