How to get started with DeepSeek
A practical, five-step path we recommend for anyone evaluating DeepSeek for the first time — designed to minimise wasted time and help you decide fast.
1Sign up for DeepSeek
Head to the official DeepSeek website and create an account. You can start with the free plan without entering payment details, which is ideal for testing how it fits your workflow.
2Set up your workspace
Install the app on web if a native client is available, or simply open it in your browser. Configure basic preferences such as language, notifications, and default output style so that subsequent runs feel consistent.
3Run your first task with DeepThink (deep reasoning)
Start with a small, low-stakes task to understand how DeepSeek responds. Write a clear prompt or input, review the output, and iterate. This low-risk exploration is the fastest way to build intuition for what the tool excels at.
4Integrate into your daily workflow
Once you know its strengths, introduce DeepSeek into one concrete workflow — not ten. Replace one existing step with it and measure the time saved or quality gained over a week before expanding usage further.
5Upgrade based on real usage
Rather than upgrading upfront, monitor which limits you actually hit (message count, output length, export features). Upgrade only when a specific limit blocks your productivity, not because the higher plan looks more attractive on paper.
