DeepSeek's web and app chat entry is comfortable with Chinese questions, coding and long reads. Answers are direct and show the reasoning, which helps you judge whether it drifted; context holds up across follow-up questions on the same material. Beyond the chat interface, it offers an API for putting the model into your own application.
What it does
- Chinese Q and A and rewriting, with natural handling of long sentences and official prose
- Code tasks: explain errors, write functions, add unit tests
- Paste long documents for summaries, key points or question-based lookup
- New conversations and history, with follow-up turns on one topic
- API access for internal systems and workflows
Who it is for
- Write, reword and organize material in Chinese at work
- Check syntax, read existing code and generate sample code during development
- Get a structured summary before reading a long report
- Put the model into an internal tool or system
How to get started
- Register, open the chat page and start a conversation
- State your role, the material and the output format in the first message instead of dropping a bare question
- Paste the source text, ask for a fixed structure, then verify item by item
