Getting Started with DeepSeek

Open the Chat

Sign up on the DeepSeek website or mobile app with email or a Google account. No install, no credit card for the free tier: you are chatting in a minute.

First Five Tasks

Ask a question needing reasoning (why do ice cubes crack in warm water?), paste a paragraph to improve, upload a photo or PDF to analyze, request a study plan, and try the same hard question with reasoning mode on versus off.

Useful Habits

Start new chats per topic so context stays clean. Save good prompts in a note: reasoning models reward well-structured questions. Check the model picker when answers feel shallow.
