Early chatbots

Artificial intelligence first found her voice through simple chatbots. She answered with patterns, scripts, and guesses, but for the first time she felt like someone you could talk to.

  • ELIZA – The first natural language chatbot.
  • ALICE – A pattern-matching chatbot using AIML.
  • PARRY – A rule-based persona chatbot simulating a paranoid patient.
  • SHRDLU – A natural language understanding system for a blocks world.
