DeepSeek App: How to Download and Use DeepSeek AI
By the Chatgbot Team · Published August 24, 2026
The DeepSeek app is a free AI assistant from the Chinese lab DeepSeek that lets you chat, write, code, and reason through problems on your phone or in a browser. You download it from the App Store or Google Play, sign in, and start typing, and the paid API is separate from the free consumer app.
DeepSeek became widely known for strong reasoning at a low cost, which is why so many people want to try the official app. This guide walks through how to get it, how to use it, what it does well, and a few privacy points worth knowing before you commit.
If you would rather not install yet another single-model app, there is also a way to use DeepSeek next to other AI models in one place, which we cover near the end.
What is the DeepSeek app?
The DeepSeek app is the official mobile and web client for DeepSeek's chat models, including the V3 general model and the R1 reasoning model. It works like most AI assistants: you ask a question in plain language, and it replies with text you can copy, refine, or continue.
The deepseek ai app is aimed at everyday tasks such as drafting emails, explaining topics, summarizing documents, and helping with code. If you are new to the tool, our guide on what is DeepSeek covers the models and the company in more detail.
DeepSeek app download: iOS, Android, and web
Getting the app is straightforward, and a deepseek app download is free on every platform. Here is where to find each version.
- iPhone and iPad: Open the App Store, search for "DeepSeek - AI Assistant", and confirm the developer is DeepSeek before you install.
- Android: Open Google Play, search for "DeepSeek", and check the developer name and review count so you do not install a copycat.
- Web: Go to the official DeepSeek website and use the chat directly in your browser, with no install needed.
The deepseek mobile app and the web version share the same account, so your chat history stays in sync when you sign in. Because DeepSeek's popularity attracted many lookalike apps, it is worth double checking the publisher and the star rating before downloading.
How to use the DeepSeek app
Learning how to use the deepseek app takes only a few minutes. After you install and open it, follow these steps.
- Create an account or sign in with email, a phone number, or a supported single sign on option.
- Type your question or task into the message box at the bottom of the screen.
- Toggle the reasoning mode (often labeled R1 or "DeepThink") when you want the model to show its step by step thinking.
- Turn on web search if you need current information rather than the model's built in knowledge.
- Read the reply, then ask follow up questions in the same thread to refine the answer.
You can start a new chat for each separate topic to keep context clean. For a deeper walkthrough of prompts and settings, see our guide on how to use DeepSeek. If you just want to test the assistant quickly, the DeepSeek chat experience runs in any browser.
What the DeepSeek app does well
The app has a few clear strengths that explain its fast growth.
- Reasoning: The R1 model is built to work through math, logic, and multi step problems, and it can show its thinking so you can follow the steps.
- Coding help: It writes, explains, and debugs code across common languages, which makes it useful for both students and developers.
- Free access: The core consumer app is free to use, so you can test real tasks before deciding whether any paid option is worth it.
- Clean interface: The chat layout is simple, and switching reasoning mode or web search on and off takes a single tap.
It is a capable general assistant, though like any AI it can make mistakes, so you should verify anything important.
DeepSeek app free vs paid
For most people, the DeepSeek app is free, and that covers the majority of everyday use. The pricing splits into two different things that are easy to confuse.
| Option | Who it is for | Cost |
|---|---|---|
| Consumer app (iOS, Android, web) | Everyday chat, writing, coding help | Free to use |
| DeepSeek API | Developers building apps on the models | Pay per usage, billed separately |
The consumer app does not require a subscription for normal chatting, while the API is a separate developer product with its own usage based billing. For a full breakdown of what is and is not free, read is DeepSeek free.
Privacy considerations to keep in mind
Privacy is worth a neutral look before you rely on any AI app, and DeepSeek is no exception. A few points to consider:
- Data location: DeepSeek is based in China, and its policy states user data may be stored on servers there, which matters to some users and organizations.
- What you share: Avoid pasting passwords, financial details, or confidential work data into any chatbot, DeepSeek included.
- Account settings: Check the app's settings for options to manage chat history or turn off using your conversations to improve models, where available.
- Workplace rules: Some companies restrict AI tools by region or vendor, so confirm your employer's policy before using it for work.
None of this is unique to DeepSeek, but the server location is the point most people ask about, so it is fair to weigh it against how you plan to use the app.
Using DeepSeek alongside other AI models
If you like DeepSeek but do not want to juggle a separate app for every model, Chatgbot is one way to use it next to other assistants. Chatgbot is an all in one AI app where a single subscription gives you access to OpenAI GPT, Claude, DeepSeek, Qwen, and GLM, so you can switch models in the middle of a conversation.
That setup is handy when you want DeepSeek's reasoning for one question and a different model's style for the next, without installing five apps or paying five bills. It also adds image generation, PDF analysis, web search, and voice in the same place. Chatgbot is honestly just one option among many, and the standalone DeepSeek app remains a solid free choice if a single model is all you need.
