Many people open chat.deepseek.com and start with “write me an article,” only to get a long, generic reply. Web chat is not about asking more — it is about making the first message clear.

Three things before you start

  1. Use the official entry: Go to chat.deepseek.com and avoid third-party clones.
  2. Pick the right model: Use the general chat model for everyday writing; switch to R1-style models when you need explicit reasoning (if available).
  3. New chat vs. continue: Start a new chat for a new task so old context does not interfere.

How to write the first message

A strong first message has four parts:

  • Who you are / context: e.g. “I am an e-commerce operator writing product detail pages”
  • Specific task: e.g. “Rewrite these selling points into 3 short paragraphs”
  • Output format: bullets, table, Markdown, word limit
  • Constraints: do not invent data; mark uncertain items as “to be verified”

Example:

I am a product manager writing feature documentation.
Turn the feature list below into user-friendly FAQ, 5 questions total.
Format: ## heading per question, answers under 60 words.
Do not add features I did not provide.

Make answers shorter or longer

Issue Fix
Too long Add “under 200 words total” or “only 3 bullets”
Too vague Attach source material or an example output
Messy format Specify JSON or a Markdown template
Off-topic Start a new chat and restate the task in message one

Useful mid-chat instructions

  • “Please reply in English”
  • “Outline first; wait for my OK before expanding”
  • “Only edit paragraph 2; leave the rest unchanged”
  • “Rewrite the last paragraph in a more casual tone”

Next steps

After your first message works, read multi-turn context management or jump into the scenario template library.
