About PromptOS
The open AI prompt library built for developers.
What is PromptOS?
PromptOS is an AI prompt library designed specifically for software developers. It gives you a single place to store, organise, and share the prompts you use every day — whether you're prompting Claude, GPT-4, Gemini, Llama, or any other large language model.
Why does it exist?
Prompts rot in chat windows. You write a great prompt, it works perfectly, and then it disappears into a conversation you'll never find again. Meanwhile, your team members are re-inventing the same prompts from scratch — or worse, shipping inconsistent results because everyone is winging it.
PromptOS solves the reusable prompt problem. It treats prompts as first-class artefacts: versioned, searchable, shareable, and indexed for the wider developer community to discover.
Features
- Save prompts — Store any prompt privately in your personal library, tagged by LLM, category, and custom labels.
- Version them — Every edit is tracked. Roll back to any previous version or compare diffs across iterations.
- Share publicly — Publish prompts to the community. Each public prompt gets its own SEO-indexed URL and a copy-to-use button.
- Search and discover — Full-text search across the public library. Browse trending prompts, filter by model, and find what works.
