Cross Sync is a shared scratchpad for moving text, links, and notes between your phone, laptop, and other devices—without signing up or messaging yourself.

Open Cross Sync on devices connected to the same network and start typing. Your text syncs in real time. Using a VPN or a different network? Create a single-use, six-digit invitation code to connect another device.

What you can do

• Share text between devices with no account required.

• Edit together in real time, with changes merged automatically.

• Connect across networks using invitation codes that expire after 10 minutes.

• Copy shared text in one click.

Cross Sync is built for quick handoffs: a link from your laptop to your phone, a snippet between computers, or notes you need on another screen.

A temporary space, not permanent storage

Text expires after 24 hours of inactivity and may disappear sooner after a server restart or deployment. Anyone in your network room, plus devices you invite, can see and edit it—so avoid sharing passwords or sensitive information.
