Promptdoo

Promptdoo is an AI prompt optimizer and skill builder. Turn a rough, vague idea into a clear, structured prompt with a defined role, context, goal, and output format, then reuse it as a "Skill" — a saved prompt building block you can generate with AI, import from GitHub, or export as a ZIP. Browse a community library of ready-to-use prompts and skills across categories like writing, development, marketing, business, education, creative work, and data analysis — and unlike a static template library, these community prompts and skills can be automatically re-adapted to your own context by the AI Assistant mode, instead of staying one-size-fits-all. Built for anyone who writes AI prompts regularly and is tired of rewriting the same rough instructions — freelancers, developers, marketers, and small teams. Free to start; credits or a subscription for heavier use.
