How to Write Great Prompts: Get Better AI Answers

A prompt is the instruction or question you send to AI (ChatGPT, Gemini, etc.). Good prompts produce accurate, usable answers.

4 Principles of a Good Prompt

1. Set a role — “You are a professional marketer”
2. State the task clearly — “Write 3 coffee ad captions”
3. Provide context — “Product costs 120 THB, target: working adults”
4. Specify output format — “Under 100 characters, in Thai”
