The Cleanest Cross Device Clipboard Solution
Traditionally, sharing text between devices meant emailing yourself, creating draft messages in chat apps, or relying on third-party cloud note tools. These methods leave your passwords and API tokens saved on remote databases indefinitely.
Textunnel establishes a direct WebRTC data stream. Copy on your phone screen, and the text syncs to your desktop browser memory immediately with zero server retention.

Frequently Asked Questions
How does cross-device clipboard sync work?
Textunnel establishes a direct WebRTC peer-to-peer data channel between your devices. Once connected in the same room, text copied on one device transmits securely and updates your recipient device clipboard in real time.
Is my copied text sent to central servers?
No. Clipboard synchronization is decentralized. Text travels directly from device A to device B via end-to-end encrypted WebRTC streams without ever touching or storing on external servers.
Do I need to install apps to sync clipboards?
No installation is required. Textunnel operates entirely in your web browser across Windows, macOS, Linux, iOS, and Android.
Can I copy and paste between Mac and Windows?
Yes! Because it is browser-based, you can bridge the gap between Apple and Windows/Android ecosystems with zero proprietary locks.
Is there any character limit for clipboard text?
No artificial limits exist. You can copy long source code files, multi-megabyte JSON payloads, or whole articles with instant delivery.
Is sensitive text like 2FA codes and passwords safe?
Yes. All data streams through DTLS 1.3 encryption directly over your local network. Once the session tab is closed, memory buffers are immediately purged.
