How to use DeepSeek: a beginner’s guide

How to start using DeepSeek

The easiest way to try DeepSeek is its free web chat at the official site, or its mobile app — sign in, type a question, and refine like any assistant. Because DeepSeek's models are open, you'll also find them offered inside other apps and platforms, sometimes at very low cost. New to it? Start with what is DeepSeek.

What DeepSeek is good at

• Reasoning and math — its reasoning models handle multi-step problems well.
• Coding — a common, capable choice for programming help.
• Cost — strong performance at a fraction of the price of many mainstream options, which is its biggest draw.

How to get better answers from DeepSeek

Nothing exotic here — the fundamentals transfer. Give it a role, the context, a clear task, and the output format you want; for hard problems, ask it to reason step by step. The same habits that make you effective with any model make you effective with DeepSeek. See how to write a good prompt, and verify anything important.

Privacy and safety considerations

As with any AI service, be deliberate about what you share. DeepSeek is operated by a company based in China, and data handling differs from Western providers, so avoid confidential, personal, or regulated information unless you've confirmed it's appropriate — and follow your employer's policy. This is good practice with every assistant, not just this one. Knowing how to use any tool safely and well is part of AI fluency; you can build it in 5 minutes a day.
