Islet
The notch Windows never had.
A Dynamic-Island-style pill at the top of your screen for music, Claude Code and Codex, notifications, battery, search and a dock of small tools. Free, open source, one installer.

Hover to open it, click anywhere else to close it. When nothing is happening Islet shrinks to a plain black pill with one dot.
The open notch, left to right: agent sessions → music → time and battery → tools.
✨ What's new
| |
|---|
| 🐾 2.3: bring your own pet | Load any pet in the Codex Pets format. The pet talks in the closed pill, codes along with your agent, asks when it needs you and plants a flower after focus sessions. |
| 📱 2.2: dock and Phone drop | A dock with Phone drop, Links, World clock, Clipboard, Notes, Timer, Shelf, Weather, Units, System and AI coding. Scan a QR code to move files between phone and PC over Wi-Fi. |
| 🔎 Search | Alt+Space finds apps, files, folders, Wi-Fi and Bluetooth switches, settings, clipboard items and notes. |
| 🍅 Focus tools | Pomodoro and stopwatch from the tray. Do Not Disturb turns on by itself during focus. |
| 🔊 Volume, brightness and mic HUD | Level bars and clean icons in the notch; a muted mic gets its own red toast. |
| 🌌 Black hole charger animation | Interstellar-style, when the charger goes in or out. Cinematic, Subtle or off. |
| 🔄 2.1: installer and auto-update | A proper installer, a welcome screen that asks before changing anything, authenticated agent hooks and updates from GitHub Releases. |
- Phone drop download links keep pointing at the file you picked, even if the shelf changes (a removed file now returns 404).
- A phone upload that is cut off no longer leaves a half-written file on the PC.
- The phone page reports network failures per file, carries on with the rest and lets you retry.
- Importing a pet from a
.zip works again.
- The downloads page no longer overlaps its header on phones.

🐾 The dock and the pet
The dock row opens a tall view with every tool, each in its own panel:
| Tool | What it does |
|---|
| 📱 Phone drop | A temporary page on your local network: scan the QR code, send files to the shelf, take shelf files back. Stops after 10 minutes. |
| 🔗 Links | Your saved links, one click away |
| 🕒 World clock | Times in other cities |
| 📋 Clipboard · 📝 Notes · 🗂️ Shelf | History with pins, quick notes, drag files in and out |
| ⏱️ Timer | Timer, Pomodoro, stopwatch |
| 🌤️ Weather | Next 6 hours and 5 days, humidity and wind |
| 📐 Units · 📊 System · 🤖 AI coding | Converter, live PC stats, your agent sessions |
The pet reacts to your PC. The first matching mood wins:
| Mood | When |
|---|
| 🤒 Sick | Battery under 20% and not charging |
