Chatbot

Conversational software

A chatbot (originally chatterbot) is a software application or web interface designed to converse through text or speech, functioning as a conversation partner. Chatbots have existed for decades, but chatbots based on deep learning have gained popularity during the AI boom of the 2020s, with the releases of generative AI (GenAI) chatbots such as ChatGPT, Gemini, Claude, and Grok. These chatbots typically use fine-tuned large language models (LLMs) to generate text.
