ChatterBot

Why we included this project

ChatterBot is a solid pick for Python teams that want a working chatbot without wiring up a large language model first. It learns the way a person learns a language by exposure: each conversation is saved as statement-response pairs, and when new input arrives the library finds the closest known statement and returns whatever reply has been given most often. You can train it on the bundled multi-language corpus or supply your own conversation data, and since the design is language-neutral it adapts to whatever language you train it on. Recent releases add semantic vector search plus optional Ollama or OpenAI backends for teams that need stronger context handling, while the plain-Python core still runs without heavy dependencies. That makes it a natural fit for prototypes, teaching bots, and simple support assistants where predictable, locally controlled replies matter.
