Description

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!
