PromptShelf — Prompt Library for AI Chats

Stop retyping the same prompts. PromptShelf keeps your best prompts on a clean shelf, one click from any AI chat — and now they're easy to share, too. WHAT'S NEW IN 1.1 • Share any prompt as a link — no account needed. Hit Share and PromptShelf builds a link that carries the whole prompt inside itself; whoever opens it can read it, copy it, or add it to their own library. Nothing is ever uploaded anywhere. • "//" quick insert — type // in the chat box on ChatGPT, Claude, Gemini or Perplexity and a menu of your saved prompts pops up right there. Filter as you type, Enter to insert. • Working {variables} — prompts with {placeholders} now prompt you to fill them in before they're inserted, from the popup or the "//" menu. • Version history (Pro) — every edit keeps its previous version; Pro can browse and restore any of the last 10. WHAT IT DOES • One-click insert — open the popup, hit Insert, and your prompt lands in the chat box on ChatGPT, Claude, Gemini or Perplexity • Save from anywhere — select great prompt text on any page, right-click, "Save selection to PromptShelf" • Copy any prompt to the clipboard when you're on an unsupported site ACTUALLY PRIVATE Your prompts are stored locally in your browser. No account, no server, no analytics, no tracking. Share links work the same way — the prompt is encoded into the link itself and never touches a server, so sharing never breaks the privacy story. The only network request the extension ever makes is verifying a Pro license key with Gumroad — and only if you buy Pro. FREE VS PRO Free: 20 prompts, sharing, "//" insert, variables — all core features, forever. Pro ($12 one-time, lifetime): unlimited prompts, folders, JSON import/export, version history restore, and every future Pro feature. Built for people who live in AI chats: writers, developers, marketers, researchers, students.
