Lightning-fast, privacy-first clipboard manager built for developers and students.
Capture everything you copy — text, screenshots, and images — and access your full history instantly.
Zero telemetry. Zero cloud. 100% local storage.
Your clipboard history — organized, searchable, and always one click away.
| Feature | Description | |
|---|---|---|
| 🚀 | Manifest V3 Architecture | Modern service worker, offscreen document for clipboard polling, and strict permission scoping. No legacy background pages. |
| 📋 | Rich Clipboard Capture | Automatically captures text, screenshots, and copied images in real-time via system clipboard polling. |
| 💾 | Immortal Favorites | A dedicated storage tier that protects important snippets from the 7-day expiry and the 50-item rolling cap. Star it, and it lives forever. |
| 🔎 | Instant Search | Fuzzy-find any snippet in your history — just start typing and results filter in real-time. |
| 🧹 | Smart Auto-Cleanup | Items older than 7 days are automatically purged. Manual single-delete and bulk-delete with a safe confirmation modal. |
| 🔍 | Filter Chips | Instantly filter your history by All, Text, or Images with a single tap. |
| ✨ | Fun Notifications | A toggleable, randomized toast notification system with custom DOM injection — shows a playful message every time you copy something. |
| 🔄 | Smart OTA Updates | A background cron job checks the GitHub Releases API every 24 hours (without rate-limiting your token) and alerts you via a non-intrusive UI badge — no nagging, just a dot. |
| 🎨 | Developer-First UI | Custom webkit scrollbars, SVG iconography, a two-view popup router (Main ↔ Settings), and safe destructive-action modals with blur overlays. |
