About Stronghold: AI Prompt Vault for ChatGPT, Claude & Gemini

Stop retyping the same prompts. Stop hunting through Notes and Docs. Stronghold is a beautiful, local-first library for the prompts you actually reuse — summoned with one keystroke inside ChatGPT, Claude, and Gemini, and inserted with another. ⌨️ A COMMAND PALETTE, NOT A DASHBOARD Press Ctrl+Shift+Space (Command+Shift+Space on Mac) — a card-catalog drawer slides open. Type a few letters, hit Enter, and your prompt lands in the chat box. Shift+Enter sends it too. Or just type // right in the message box. 🔒 YOUR PROMPTS LIVE ON THIS DEVICE No account. No cloud — unless you back up to your own Google Drive. No analytics, no tracking, no servers of ours. The privacy policy fits on a napkin because there's nothing to confess. 🗂 ONE LIBRARY FOR ALL THREE CHATS ChatGPT, Claude, and Gemini share the same shelf. Everywhere else, the palette works in clipboard mode — search, Enter, paste. ✏️ FILL-IN-THE-BLANK PROMPTS Write {{topic}} or {{tone|formal,casual,playful}} once; get a fill-in form every time, with your last answers remembered. 📚 STARTS USEFUL 25 crafted Starter prompts ship in the box — an editor that red-teams your drafts, a debugger that diagnoses before it cuts, a negotiation cornerman, a 30-day skill plan, and more. Variables work on all of them, free. — FREE — • 50 prompts • Command palette + // trigger • Insert into ChatGPT / Claude / Gemini • Collections, tags, fuzzy search • The 25-prompt Starter Shelf • JSON export & import — your data is always portable — PRO ($4.99 once. Yours forever, like your prompts.) — • Unlimited prompts • Variables on all your own prompts • Backup & sync via your own Google Drive (a file you own, in your account — we never see it) • Version history with diffs No subscription. No account. Just your prompts, one keystroke away.
