What Is the DeepSeek App?
The DeepSeek app is the official mobile application created by the company behind the DeepSeek AI assistant. It allows you to chat with an advanced AI language model directly from your smartphone or tablet, without needing a computer. The app first gained worldwide attention shortly after its release, when it quickly climbed to the top of app store download charts in the United States and many other countries.
At its core, the app lets you have natural conversations with AI. You can ask it to explain difficult topics, help draft emails and documents, brainstorm ideas, write and review code, summarize long text, and much more—all through a simple, clean chat interface.

The official DeepSeek app focuses on a clear, useful set of features designed to make AI helpful in everyday life:

- Web search: The app can search the internet to find current information and summarize it into clear, concise answers.
- File and image upload: Upload documents and images, or take a photo, and ask the AI to read, analyze, or summarize the content.
