PromptAtlas

What it does

PromptAtlas is a free place to store and reuse AI prompts. You sort prompts into folders, add colored tags, wrap changing parts in {variables}, and every edit keeps the previous version. It works offline, installs like an app on your phone, and exports your whole library to JSON, Markdown or CSV.

PromptAtlas is a calm home for prompts you reuse instead of letting them die in a chat history. You file prompts into folders per project and add colored tags, so the same prompt can sit under a client and under #seo at once. Parts that change go in {curly braces} and you fill them in at reuse time. Every save keeps the previous text, so you can read or restore an earlier version. Search covers titles, prompt bodies and tags together. You can publish a prompt as a public link or browse the community Explore feed. The site says every feature is free, with no paywall, no Pro tier and no limits on prompts, folders, tags or versions. If you want to run prompts inside the app, you add your own API key for OpenAI, Anthropic, Google or Mistral and pay the provider directly. The page does not say whether an account is needed to start, and it does not state a software license.
