DeepSeek for students has become a common search as the assistant spread across campuses. Before you rely on it for studying or projects, it is worth knowing what it offers, how to use it in a way that actually helps you learn, and what its terms and privacy policy say about your data. Everything here comes from DeepSeek's official site and published documents.

## Where to find DeepSeek

DeepSeek's official site points to web chat at chat.deepseek.com and shows a code to download the mobile app. Its terms of use say you register with your email or a third-party account, following the page instructions, and that your information must be accurate.

1. **Use the official site**: Go to chat.deepseek.com or get the app from the link on deepseek.com. Check the address, as copycat apps and sites use the name.
2. **Sign up**: Use your email or one of the third-party accounts offered on the sign-up page.
3. **Check privacy first**: Open settings and look at the chat history options before you upload any file.
4. **Try the modes**: The official interface shows DeepThink and Search. Pick based on the type of question.

## DeepThink and Search: when to use each

DeepThink is the extended reasoning mode: the model takes longer and works through steps before it answers. It suits maths, programming and questions that need analysis. Search lets the assistant look things up on the web, which helps with questions that depend on recent information. For simple questions or rewording, a normal chat is enough and faster.

| Type of question | Mode to use |
|---|---|
| A maths or physics problem, step by step | DeepThink |
| A bug in your code | DeepThink |
| Recent information or news | Search |
| Explaining a concept or summarising a short text | Normal chat |
| Rewording a paragraph | Normal chat |

## Study prompts that work

Understand, do not copy:

```
Here is my problem: [paste it].
Do not give me the final answer. Give me only the first step and ask me what comes next. Correct me if I go wrong, and at the end summarise the method in three points.
```

Review my code:

```
This is [language] code for an assignment about [description]: [paste code].
Do not rewrite it. Point to the lines with problems, explain why, and suggest a fix for each line.
```

Quiz me:

```
I am studying [topic] for [course]. Ask me one question at a time and wait for my answer. After ten questions, tell me my weakest area.
```

> **Tip**: DeepSeek's terms say outputs may contain errors or omissions and are for reference only. Check any number or fact against your course material before you use it in graded work.

## What the terms of use say

- The service is primarily intended for adults. Users under 18 should read the terms with a guardian and use it with their consent.
- You keep your rights in your inputs, and DeepSeek assigns to you any rights it has in the outputs, noting that outputs may be similar to those given to other users.
- Academic research is listed as a permitted use, as long as it is legal and follows the terms.
- Outputs are not professional advice. For medical, legal or financial matters, consult a qualified professional.

## Privacy: the key point before you upload

DeepSeek's official privacy policy says it collects text and voice input, uploaded files, photos, feedback and chat history, plus device and network details and approximate location from your IP address. It states that it directly collects, processes and stores personal data in the People's Republic of China, and keeps account and input data for as long as you have an account.

- Data may be used to train and improve its models, and you have a right to opt out by emailing the privacy address in the policy.
- You can copy or delete your chat history in settings.
- Deleting your account is permanent and the content cannot be recovered.

The practical advice: do not upload unpublished research, participant data, or documents with personal information. To compare privacy settings across tools, read [AI privacy tips for students](https://tiswa.app/en/blog/ai-privacy-for-students/).

## Can it replace ChatGPT, Claude or Gemini?

Each tool has strengths, so choose by task and by how comfortable you are with its data policy. We compared DeepSeek and ChatGPT point by point in [DeepSeek vs ChatGPT](https://tiswa.app/en/blog/deepseek-vs-chatgpt/), and the big three in [ChatGPT vs Claude vs Gemini](https://tiswa.app/en/blog/chatgpt-vs-claude-vs-gemini/).

## A practical way to compare answers

Many students use DeepSeek as a second tool to check another assistant's answer, especially on long multi-step problems. Comparing helps when it is organised and wastes time when it is random. Try this:

1. **Paste the exact same question**: Use the same prompt in both tools, with the same data and the same requested format.
2. **Compare the steps, not just the answer**: If both reach the same answer by different routes, go back to the method your lecturer used.
3. **Ask about the disagreement**: Write: the other tool got a different result at step three, explain which method is right and why.
4. **Go back to the source**: The final word belongs to the course textbook or the lecturer's solution, not to any tool.

A disagreement between tools is a useful signal: it points to something you need to understand yourself, and that is often what turns up in the exam.

> **Tip**: If you use DeepSeek in a group project, agree with your team on which files you upload, and never upload a file a classmate wrote without asking, because the privacy policy applies to everything uploaded from your account.

## A sample study session

Here is what a good 30-minute session looks like with any chat tool. First, five minutes reading your own lecture notes on one topic. Then ask the tool to quiz you with five questions on that topic, without answers. Answer them in writing. Ask the tool to mark your answers and explain only the ones you got wrong. Finish by writing a short summary in your own words and comparing it with your notes. If you prefer to plan these sessions across the week, use the [AI study planner](https://tiswa.app/en/blog/ai-study-planner/), and if you want sharper prompts, read [prompt writing basics](https://tiswa.app/en/blog/prompt-writing-basics/).
