Radionuclide Explorer: This is an interactive resource for learning about common radionuclides used in nuclear medicine. It emerged out of curiosity: How far could an AI coding agent get with a real reference site in a single session? The whole thing including the layout, dataset and decay animations, was built in roughly one hour entirely by Claude Code, with only a few minor improvements.

Interactive lessons in math, programming, data analysis, AI, and science.

just leaving a comment cause its 1am and im vibe coding, will come back tomorrow (on an alt account for open claw fyi) I've worked with the following brands: vytadose, bajabeachco, jaje health, eric javits, 4knines, welleco, coatdefence

Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

Learn math, science, finance through 450+ interactive mini-games and lessons.

Don't let your LLM guess the math. Ultimath evaluates every expression with five independent numeric engines in parallel — REST API + MCP for Claude.

Not vibe-coded, rather AI assisted dev:

Refine ideas through logical reasoning and publish them to a community of verified knowledge.

I vibe coded a demo for grading, not in a great shape but it's fun to play a bit.

Turn school topics and confusing text into interactive stories and infographics.
