- People learning technical docs for work
- Worth noticing
- A sample “How LLMs work” map has 11 stops; checkpoint questions test transfer beyond the lesson cards.
Field notes
The sample lesson asks learners to choose why a chatbot may give different answers, then uses checkpoints to test understanding in situations beyond the cards. The setup path uses Bun and a local development server; the page also describes a terminal review option. For provider-based use, it says a monthly spend cap and a log of what was sent are available, while Ollama is presented as the fully offline option.
