ChatGPT
GoodThe most used AI assistant. Chat, images, voice.
Which free AI chatbot is best?
The big free AI assistants, ChatGPT, Google Gemini, Claude and Microsoft Copilot, are close enough that the best one is the one you will actually use. All have free plans that write, explain, summarize and answer questions. Perplexity is best when you want sources linked for every answer. Never paste passwords, bank details or private medical records into any of them.

Good to know
- AI assistants can state wrong facts confidently. Check anything important, like health, money or legal answers.
- We make no pick here because this site is partly written with AI help, and we would rather not judge ourselves.
