Free AI tools: what is available and what are the limits?

Almost every major AI assistant has a free version: OpenAI's ChatGPT, Google's Gemini, Anthropic's Claude, Microsoft's Copilot and Meta AI. You can open an account and start in the browser or the phone app right away. Meta's new agent Muse also comes with a free plan, although for now it is only available in the US.

Free plans usually limit how many messages you can send in a given period, access to the most capable models, file and image uploads and voice features. The limits change often and usually reset every few hours. Whether to move to a paid plan is best decided after a few weeks of seeing how far the free version gets you.

In many free consumer versions your conversations can be used to improve the models unless you turn this off in settings. Check the privacy settings of the tool you use and consider opting out of training if the option exists. Free versions are not the place for customer details, personal data or company secrets.

Open weight models (such as Meta's Llama, Google's Gemma, Mistral, Qwen and DeepSeek models) can be downloaded for free and run on your own computer. Apps such as Ollama and LM Studio make this a few clicks. Your data stays on your machine; in return you need a capable computer, and these smaller models are not as capable as large cloud models.

Writing a clear prompt is the best way to stretch a free limit, because you reach the right answer in fewer messages. Keeping long tasks in one conversation, asking the same question in different tools and always checking important facts also help. To pick the right tool for you, see our guide on the best AI.
