Phone Keyboard

Type into any input on your laptop from your phone over local WiFi.

Type into your laptop's Chrome from your phone — over your local WiFi, with nothing leaving your network. Click any text box on your computer, then type it out on your phone. The text appears live in the selected input on the laptop. Built to make one-handed laptop use comfortable (for example, when an arm is in a cast), but handy any time your phone's keyboard is faster than reaching for the laptop. FEATURES • Type on your phone → text streams into the selected input on the laptop, live. • Two-way sync — edits on either device stay in step. • A Send button presses Enter, so you can submit search boxes, chats, and forms. • Message history with collapse, star, resend, and reset. • A floating, draggable bubble in the browser for connection status and settings. • An optional desktop app (macOS + Linux) so non-technical users never touch a terminal. HOW IT WORKS A Chrome extension can't host a server, so there are three small parts that talk over WebSockets: Phone (web app) ⇄ Local relay server (on the laptop) ⇄ Chrome extension The relay server runs on your own laptop. The extension always connects to 127.0.0.1 (localhost), so there are no mixed-content issues and it needs no token. Your phone connects over the LAN and must present a token that's baked into its URL/QR code. WHAT YOU NEED • A laptop and phone on the same WiFi. • Google Chrome (or Chromium) on the laptop. • The relay server running on the laptop — either the desktop app (one click to start) or via Node.js from the terminal. WHY IT EXISTS I built Phone Keyboard for my girlfriend after she dislocated a finger and spent weeks with her arm in a cast, which made typing slow and painful. I hope it makes working at a laptop a little easier for you too. PRIVACY • No data leaves your network. There is no cloud component and no analytics. • LAN clients (your phone) must present a token, embedded in the QR/URL — keep that link private. • The extension connects only to localhost and needs no token.
