The ChatGPT Prompts Library
The most useful ChatGPT prompts on the internet, organized by job-to-be-done. Every prompt is tested against GPT-5 and GPT-4o, copy-ready, and free to use.
Simple AI Prompt is a working library, not a wall of generic 'write a blog post about X' prompts. Each entry includes the exact instruction text, the model it was tuned on, when to use it, and how to repurpose it for your own workflow.
Our ChatGPT prompts cover content writing, sales outreach, customer support, coding, data analysis, product strategy, education, healthcare, legal drafting, finance, and 30+ other domains. New prompts are reviewed and published every week.
Pair any of these with our Loop Library - short named instructions you can chain after a ChatGPT prompt to bend the model's reasoning in a specific direction.
