KeyPrompt — AI Prompt Library

Cmd-click any AI chat to insert your saved prompts. Works in ChatGPT, Claude, and any text field. Local, zero tracking.

🔑 KEYPROMPT — A prompt library for AI power users. Good prompts are craft. The difference between a generic image and a striking one is often a paragraph of carefully-tuned language — lighting, camera, style, mood, negatives. The difference between mediocre and great LLM output is the same. Once you've found a prompt that works, you'll want to use it again, tweak it, share it, build on it. KeyPrompt is the lightest possible tool for keeping those prompts close at hand. Cmd-click (Mac) or Ctrl-click (Win/Linux) any chat input on any AI tool — including ChatGPT, Claude, and others — and a small modal appears with your saved prompts. Pick one. It's in the field. No more digging through a notes app or dozens of open browser tabs. You can also right-click any input and pick "🔑 Insert with KeyPrompt" from the OS context menu. ═══ WHO IT'S FOR ═══ • AI artists who tune image and video prompts into something repeatable • Developers who keep "explain this code," "write a test for this," and "summarize this PR" prompts on tap • Writers and editors with a stable of system prompts for tone, structure, and edits • Marketers running variations of the same generation prompt across tools • Anyone tired of pasting from a Notes window into a chat for the hundredth time ═══ HOW IT WORKS ═══ 1. Click the KeyPrompt icon in your toolbar to open the prompt library. 2. Add your prompts — organize them into sections like "Image prompts," "Code helpers," "System prompts." 3. On any AI tool, Cmd-click (Mac) or Ctrl-click (Win/Linux) inside the prompt box — OR right-click and pick "🔑 Insert with KeyPrompt." 4. The modal appears with your library, searchable. 5. Type to filter, arrow keys to navigate, Enter to insert. 6. Done — the prompt is in the field, the modal closes. ═══ WHERE IT WORKS ═══ KeyPrompt works in every text input on every website. That includes major AI chat interfaces such as ChatGPT and Claude, as well as image and video generators with text prompt boxes. It also works in regular text fields — emails, signup forms, any place you find yourself retyping the same text. Same product, broader use case. ═══ FEATURES ═══ ✓ Two ways to summon — Cmd/Ctrl+Click for speed, right-click for discoverability ✓ Works in every editor type — <input>, <textarea>, contenteditable, and rich AI prompt boxes ✓ React / Vue / Svelte friendly — uses native value setters and dispatches input/change events so modern AI UIs see the change ✓ Search-as-you-type with full keyboard navigation ✓ Shadow-DOM isolated — host page styles can't touch the modal ✓ Local-first storage (~10 MB ceiling — plenty for paragraphs of prompt detail) ✓ Full Import / Export of your prompt library as JSON for backup ✓ Live sync across your open tabs ✓ No accounts, no servers, no analytics, no third-party SDKs ═══ PRIVACY ═══ Your prompts never leave your browser.

Full privacy policy: https://themodernspirit.github.io/keyprompt/PRIVACY ═══ WHY EACH PERMISSION? ═══ KeyPrompt requests these permissions for a single, specific reason — never for tracking or data collection. • "Read and change all your data on all websites" — required to detect Cmd-click on prompt boxes and insert text. KeyPrompt does not read page content; it only reacts when you intentionally trigger it. • Storage — to save your prompts locally on your computer. • Scripting + Tabs — to refresh KeyPrompt cleanly across your open tabs whenever the extension is updated, so you never have to manually reload. • Context menus — to show "🔑 Insert with KeyPrompt" in the right-click menu. ═══ OPEN SOURCE & FREE ═══ KeyPrompt is open source under the MIT license: https://github.com/themodernspirit/keyprompt It's free forever.
