DeepSeek

DeepSeek is an AI assistant made by the Chinese AI company DeepSeek. It runs in a browser at chat.deepseek.com and in mobile apps, and you sign in to use it. You type a request in plain language and it answers — drafting text, explaining topics, reasoning step by step, and writing and debugging code.

It drew wide attention for delivering strong reasoning and coding performance at low cost, and the assistant is free to use. It handles the usual range of language and reasoning tasks well and offers a reasoning mode that shows its working on harder problems.

A data-handling point stated plainly, not hidden: DeepSeek is a Chinese company and its consumer service is hosted in China, so conversations are processed on servers there and handled under Chinese law and DeepSeek's own policies. Several governments and organisations have restricted the app on official devices over data-privacy concerns. Treat it as you would any service where your input leaves your control — avoid sending personal, confidential, or sensitive information, and check whether your employer or region permits its use.

With that understood, it fits developers and curious users who want a capable, free assistant for coding and reasoning and are comfortable with where it runs. To begin, create an account at chat.deepseek.com — no credit card for the free assistant.

The honest limits. As with any assistant it can be fluent and wrong, so verify anything important. The service can be busy or rate-limited at peak times, and features and availability can change. DeepSeek's developer API is a separate, paid product billed apart from the free chat assistant.
