Show HN: Rebrain.gg – Doom learn, don't doom scroll

29•FailMore•11h ago
Hi HN,

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!

Doom scrolling is when you just have to flip up. Maybe swipe if it's an advanced app.

This is something else entirely and requires far too much thinking for the label.

Improving the UI would only take you a few prompts

My feedback reiterates what you're hearing about the cogintive load being unruly. If you want to "beat" doom scrolling, you need your mechanics to be as simple -- quick swipes and taps.

One potential direction, simple cards that are True/False.

I think you should use nano-banana to auto matically create a "youtube short" that might make this more addictive like doomscrolling

I am not a big fan of AI-generated educational content, mostly because it's a great way to confidently learn falsehoods and misconceptions. I would prefer to learn from a reliable and reputable source.

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.

This was a couple of years ago, but I remember using ChatGPT to try and study for a certification by generating quiz questions.

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!

The example you gave is just so buggy; why do you think that this is worth sharing with the world yet?

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.

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 :]

Upon clicking ‘continue’ or ‘submit’, make it transition to a different color which will give a good user experience

I thought this would teach you random facts in one-screen-sized tiles. This doesn't look like doom scrolling. But I like the idea of the user picking a subject, maybe combine both: pick a subject, it gives you facts about it, maybe a tile to ask for which path to take once in a while (swipe left to keep learning about find, swipe right to learn about xargs).
wpollock•13m ago
An interesting approach, Good luck with it! A nit to pick: find is not a bash command. You can run it for example from a Windows DOS command line as:

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).
