Compare AI chatbots for everyday help, customer support, website bots, character chat, and free plans — from general assistants to ChatGPT alternatives.
An AI chatbot is a program you talk to in plain language, powered by a large language model (LLM). It replies in context, remembers earlier turns, and can search the web, read documents you upload, or call other tools. They range from general assistants like ChatGPT and Claude to narrow bots embedded on a website to answer customer questions.

Most chatbots run on a large language model trained on huge amounts of text. Given your message and the earlier conversation, it predicts a helpful reply token by token. Bots that answer from your content add retrieval — pulling relevant passages from your documents first — and extras like web search or code execution are added as tools the model can call.
