About PromptPack
PromptPack is a free library of ready-to-use prompts for ChatGPT, Claude, Gemini and image tools like Midjourney. It exists for one reason: most people get weak results from AI because they write vague requests. A good prompt works like a good brief — it says who the AI should act as, who the result is for, what the goal is, and what shape the answer should take. We write those briefs so you don't have to start from a blank box.
What you'll find here
- Prompt packs by profession — 14 packs of 15 prompts each for teachers, marketers, recruiters, developers and more, free to download with an account.
- Guides and articles explaining how to structure prompts, compare models and avoid output that sounds machine-written.
- Free browser tools such as the Prompt Optimizer, Prompt Builder and System Prompt Architect. They run entirely in your browser — nothing you type is sent to us.
- Community prompts submitted by readers. Every submission is reviewed by hand before it's published.
How prompts are written and checked
Each prompt follows the same structure: a role, the context, the task, constraints, and an output format. Before a prompt goes into a pack we run it in at least one current model, read the output, and rewrite the prompt if the result is generic, padded or wrong. Prompts use [brackets] for the parts you fill in, so they work for your situation rather than ours.
AI models change often. When a model update changes how a prompt behaves, we revise the prompt and the article that explains it. If you find a prompt that no longer works well, tell us through the contact page and we'll fix it.
What we won't do
- Promise results. A prompt is a starting point; you still need to check facts and edit the output.
- Publish example outputs as if they were real results without labelling them as illustrations.
- Sell your email address or what you type into our tools.
