Chatbot — AI tools

AI chatbots are conversational assistants you interact with in plain language — ask a question, get a written answer, and keep the conversation going. The best ones handle a huge range of everyday knowledge work: drafting emails, explaining difficult topics, summarizing documents, writing and debugging code, and brainstorming ideas. They are the most versatile category of AI tool and, for most people, the first one worth trying.

When choosing a chatbot, weigh three things: the quality of the underlying model (reasoning, accuracy, and how current its knowledge is), the price and generosity of any free tier, and the ecosystem around it — mobile apps, browser extensions, file uploads, and integrations. Heavy users usually benefit from a paid plan for faster, smarter responses, while occasional users can get a long way on free tiers. Below are the chatbots we rate most highly and who each one suits best.
