Hey Product Hunt 👋 I'm building PromptStash — a prompt library that lives across every AI chat site (ChatGPT, Claude, Gemini, Perplexity, Grok). Why I built this: I had 47 prompts saved in a Notion doc and was constantly copy-pasting them into different AI chats. Existing tools either inject ugly toolbars (👋 AIPRM) or only work on one platform. How it works: - Type /pp in any AI chat input → your library opens inline - Variables like {{topic}} become a tiny fill-in form - Cmd/Ctrl+Shift+P shortcut from anywhere - Folders, search, keyboard-first navigation I shipped with 25 hand-crafted starter prompts following the R-T-A-C-F framework (Role · Task · Audience · Constraints · Format) so new users have value in under a minute. Pricing: Free up to 50 prompts (25 starter + 25 yours). Pro $5/mo for unlimited + cloud sync (coming soon) + AI prompt enhancer (coming soon). Currently in Chrome Web Store review (round 2 — first attempt got rejected for a screenshot showing a mock "Add to Chrome" button, fair enough lol). Subscribe to this page to get the install link the moment Google approves. Privacy-first: local-only storage. We never read your AI conversations. No telemetry. Happy to answer questions about the build, pricing strategy, or tech choices (Manifest V3, no remote code, vanilla JS). Built in public on X: @promptstash_app
