Tiny LLM Creator Kit

A platform that lets anyone train a small language model with their own data/personality without ML expertise. Users could create custom chatbots or characters by uploading conversations or text, then deploy them. Targets indie devs, content creators, and hobbyists who want personalized AI without cloud costs.

The explosion of open-weight models like Llama and Mistral has made local fine-tuning genuinely accessible for the first time, and tools like Unsloth have collapsed the compute cost enough that a consumer-grade GPU can now fine-tune a usable model in hours — that's the window this sits in. Character.AI and Replika dominate the end-user side, but neither lets creators own or export the underlying model, which is the real differentiator here. The $500–2k/mo revenue band is realistic but tight — fine-tuning pipelines are infrastructure-heavy, and GPU costs will eat margin fast unless the platform runs on quantized models or offloads compute to the user's machine. The biggest risk is that Hugging Face, Ollama, or a well-funded competitor ships a polished no-code fine-tuning UI before this gains traction, since the technical barrier to building the core feature is low enough that it won't stay uncontested long.
