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:…

Hi HN, we’re Jamie and Matti, co-founders of Twigg. During our master’s we continually found the same pain points cropping up when using LLMs. The linear nature of typical LLMs interfaces - like ChatGPT and Claude - made it really easy to get lost without any easy way to visualise or navigate your project. Worst of all, none of them are well suited for long term projects. We found ourselves spending days using the same chat, only for it to eventually break. Transferring context from one chat to another is also cumbersome. We decided to build something more intuitive to the ways humans think.…

Hi HN! I've found this visualization tool immensely helpful over the years for getting an intuition for how an LLM "sees" some piece of text, and with a bit of elbow grease decided to move all compute to client side so I could make it publicly available. I've found it particularly useful for - Understanding exactly how repetition and patterns affect a small LM's ability to predict correctly - Understanding different tokenization patterns and how it affects model output - Getting a general sense of how "hard" different prediction tasks are for GPT-style models Known problems (that I probably…
