Return of the Coder
Live demonstration

Teach it facts. Ask it questions. No LLM.

Natural language understanding running entirely in your browser. Tokenize → parse → interpret → recall → infer → answer. Everything traceable. Nothing phoned home.

Try in order: "Mars is a planet." · "Mars orbits the Sun." · "Is Mars a planet?" · "What does Mars orbit?"

Built from the Return of the Coder method — a parser, spelling corrector, knowledge base, inference engine, and response generator, each written by hand with gold-file-driven development. No neural network at runtime. No API calls. No subscription.
