About DeepSeek models
DeepSeek is a family of large language models developed by the Chinese AI lab DeepSeek. Its general chat model, DeepSeek V3, is known for strong results in coding and math at a fraction of the cost of comparable models. DeepSeek R1 introduced open reasoning: the model writes out its thinking before giving the final answer, which makes it easy to check how it arrived at a solution.
This site lets you talk to DeepSeek models directly in the browser, without downloading an app or creating an account. Answers are generated by AI and can contain mistakes, so check important facts, figures and code before relying on them.
Frequently asked questions
Is DeepSeek Chat on this site free?
Yes. Every visitor gets a set of free messages each day, and the allowance resets every 24 hours. There is no subscription and no payment form.
Do I need an account or a phone number?
No. Open the chat and type. There is no registration, email confirmation or phone verification.
What is DeepThink mode?
DeepThink makes the model reason step by step before it answers, the way DeepSeek R1 does. You can expand its reasoning to see how it reached the result. It is slower, but better for math, logic and tricky code.
Where are my conversations stored?
Your chat history is saved only in your own browser. Clearing site data or switching devices removes it. We do not keep a copy of your conversations tied to you.
