PromptPaste is a native Apple app that lets you save, organize, and instantly paste AI prompts from a Mac menu bar overlay or iOS share sheet. Hit ⌘⇧P anywhere on Mac and your entire prompt library is accessible without switching apps or hunting through notes. The app supports dynamic templates using {{variable}} placeholders so prompts can be customized at paste-time, folder-based organization, iCloud sync across all Apple devices, and link-based sharing of prompt collections. Crucially, everything is stored locally — no account required, no cloud sync of your actual prompts outside of iCloud. Built by indie developer Ivan Terehin, PromptPaste fills a genuine gap: most people accumulate dozens of AI prompts scattered across notes, docs, and chat history. Works with every major AI platform — ChatGPT, Claude, Gemini, Grok, Midjourney, GitHub Copilot, and more.
Reviewer scorecard
“The free tier is genuinely usable. Rare for this category.”
“For creators who use AI daily across writing, image generation, and video tools, having a single organized library across Mac and iPhone with variable templating is exactly the kind of workflow glue that saves an hour a week.”
“Fast, reliable, and the docs are actually good. Ship.”
“The ⌘⇧P hotkey that drops your prompt library anywhere is the feature I didn't know I needed. I have system prompts, code review templates, and git commit formats that I paste constantly — having them one keystroke away instead of buried in Notion is a real productivity win.”
“This is a well-executed clipboard manager with an AI marketing angle, not really AI itself. Raycast and Alfred already do this with snippet libraries, and most power users are already in those ecosystems. The Apple-only constraint also limits its audience significantly.”
“Personal prompt libraries are the new dotfiles — the accumulated knowledge of how to get AI tools to work for your specific workflows. Apps like PromptPaste are the beginning of a whole category of 'AI configuration layer' tools that will become essential infrastructure.”
