Input Leaf is an open-source Android client for Input Leap — a KVM software switch that lets you control your Android device using your PC or laptop's existing mouse and keyboard.
Simply move your cursor to the edge of your screen on your PC, and it seamlessly crosses over to your Android device — no extra hardware, no USB cables, just your local network.
🖱️ PC/Laptop mouse & keyboard → controls your Android device
To use Input Leaf, you must have the following set up:
- Input Leap — The server must be running on your PC or laptop. Input Leaf connects to it as a client over your local network.
- Input method — pick one:
- Shizuku (recommended) — Rootless, system-level mouse & keyboard injection with the lowest latency.
- Accessibility Service (no-root alternative) — Works on any stock Android device with no extra apps. Enable Input Leaf in Settings → Accessibility to use it.
Both methods can be active at the same time. Shizuku takes priority when available.
- Seamless Input Sharing — Use your PC's mouse and keyboard to control your Android device, just like an extra monitor.
- Dual Input Methods — Shizuku for max performance, Accessibility Service for plug-and-play compatibility.
- Auto-Reconnect — Automatically reconnects to the last server after a network drop, with exponential back-off.
- Modern UI/UX — Beautiful Material interface with color-coded connection statuses.
- Easy Toggling — Quickly enable or disable input control on the fly.
- Server Discovery — Automatically scan your local network for active Input Leap servers.
- Quick Favorites — Save frequently used servers for one-tap connections from the home screen.
- Guided Setup — Built-in 5-step wizard for configuring input methods and required system permissions.
- No Root Required — Works entirely through Shizuku or the Accessibility Service, keeping your device secure.
- TLS-Secured Connection — Trust-on-first-use (TOFU) certificate pinning for encrypted connections.

| Latency | Lowest (Direct Injection) | Low |
1. Shizuku (Seamless Injection) This is the recommended method. Shizuku allows Input Leaf to inject mouse and keyboard events directly at the Android OS level.
- Pros: Extremely low latency. System-level keyboard shortcuts (like
Alt+Tabfor recent apps,Windows+Dfor home screen, etc.) work exactly like they would on a physical Bluetooth keyboard. - Cons: Requires the one-time setup of the Shizuku app via Wireless Debugging or ADB.
2. Accessibility & Virtual Keyboard This is a pure plug-and-play fallback. It uses Android's Accessibility APIs to emulate touch events for the mouse, and sets Input Leaf as your active software keyboard to receive keystrokes.
- Pros: No extra apps required. Works out of the box by just granting Accessibility permissions and selecting the keyboard.
- Cons: Because it's a software keyboard, it cannot capture hardware-level OS shortcuts like
Alt+TaborMetakey combinations. Mouse movement is simulated via touch gestures, which can feel slightly different than true hardware injection.
