Prompt Engineering: 100 Practical Prompts

Write reusable prompts that get reliable results for study, office work, marketing, data and creative tasks. Most people get average answers from AI because they write average prompts. This book gives you a repeatable system for writing prompts that work the first time — and 100 ready, categorised prompts you can adapt in seconds for study, office, marketing, data, coding, design and planning tasks.

Who this eBook is for

Students, working professionals, teachers, content creators and small business owners who already use AI tools such as ChatGPT, Gemini, Claude or Copilot and want consistently better results. Beginners can follow along too — Chapter 1 starts from the basics.
