Personal LLM Character Creator

People want to experiment with AI and understand how language models work without deep ML expertise. A platform that lets anyone train a tiny LLM with custom personality data in minutes using free cloud compute. Target users: AI enthusiasts, educators, hobbyists.

The democratization wave in AI tooling is real — Hugging Face, Replicate, and Google Colab have lowered the floor significantly, and there's genuine hobbyist demand following the ChatGPT explosion. No clear incumbent owns the "train your own tiny model" niche for non-technical users, though Character.ai captures adjacent demand by letting people *use* custom personas without touching weights. The $300–1.5k/mo revenue band is honest given the audience: hobbyists and educators rarely convert to paid tiers at high rates, and free compute arbitrage only lasts until cloud providers tighten policies. The most likely failure mode is that "train in minutes" either means fine-tuning a small model that produces underwhelming results — killing retention — or it means prompt engineering dressed up as training, which users eventually see through.
