About

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.
