Interactive LLM Learning Sandbox

A hands-on platform where developers and students can train tiny language models from scratch to understand how transformers work. Users fork a base model, customize the training data/personality, and see results in minutes on free compute. Perfect for education and demystifying AI.

Demand for AI literacy tooling is genuinely surging right now — bootcamps, universities, and self-taught developers are all scrambling to move beyond prompt engineering into actual model mechanics, and existing resources (Andrej Karpathy's nanoGPT, fast.ai) are free but raw, with no guided sandbox layer on top. No clear incumbent owns the "interactive transformer training" space as a product, which is the opening. The $1k–5k/mo revenue band is realistic only if you commit to a B2B angle fast — individual learners rarely pay, so the real path is licensing to coding bootcamps or university courses, where a single cohort deal can justify the number. The biggest risk is that the free alternatives are good enough: if a motivated developer can clone nanoGPT and run it on Colab in 20 minutes, the activation energy for a paid product needs to be dramatically lower than it currently sounds.
