A clipboard/gallery manager for AI prompts. Save reusable prompts once and inject
them into Claude, ChatGPT, Gemini, or any text field — from a browser extension
or the web app. No backend: prompts live in your own Google Drive
(vault.json, drive.file scope); the app just reads/writes it.

System-aware dark / light — the same UI in the extension and the web app:
| Dark | Light |
|---|---|
 |
 |
| Path | What |
|---|---|
packages/core |
Framework-agnostic data model + Google Drive client + last-write-wins/tombstone sync engine. Injected AuthProvider + LocalCache adapters. Vitest. |
apps/extension |
Manifest V3 extension (vanilla JS, esbuild → dist/). chrome.identity auth, chrome.storage cache, context-menu + popup injection, dashboard, onboarding. |
apps/web |
Svelte + Vite static site: marketing landing at / + portal at /app. Google Identity Services auth, IndexedDB cache. Deployed to Firebase Hosting. |
The extension and web app share one library via the Drive vault.json, reconciled by core.
