A custom keyboard for using LLM CLI agents (Claude Code, OpenClaw, etc.) from your phone. Android keyboard extension + iOS terminal app.

Install

Android

Free version: Download the lite APK from GitHub releases. Includes voice input, clipboard history, slash commands, swipe gestures, and per-app autocorrect.

Full version ($4): Buy on the website via Stripe. After purchase, you'll get an email with a private download link (expires in 7 days). New versions are emailed automatically.

After installing:

1. Go to Settings > System > Languages & input > On-screen keyboard
2. Enable KeyJawn
3. Set KeyJawn as your default keyboard

iOS (beta)

The iOS version is a standalone terminal app, not just a keyboard extension. It has a built-in SSH client (SwiftTerm + SwiftNIO SSH) so you can connect directly to your servers. A companion keyboard extension adds Esc, Tab, Ctrl, arrows, and slash commands to any app.

Currently in TestFlight beta. App Store launch coming soon.

To use the keyboard extension in other apps after installing:

1. Go to Settings > General > Keyboard > Keyboards > Add new keyboard
2. Select KeyJawn Keyboard
