After sharing [til.re](https://news.ycombinator.com/item?id=46483121) (a minimal countdown timer) here, I built another small tool: cross-device text transfer without accounts or apps.

*How it works:*

1. Go to `tmp.tf#yourchannel` on one device

2. Paste your content

3. Open the same URL on another device — done

The channel name is the password. Use something like `#a9$Kx2m` for private transfers, or `#meeting-notes` for easy sharing.

*Features:*

- URL-as-state: the channel name lives in the URL, easy to share

- Auto-expires (no manual cleanup)

- Works in any browser

- Deployed on Cloudflare edge network

I also made a dark-themed version at *copypa.st* if you prefer that aesthetic.

Built this because I got tired of emailing myself links just to move a snippet from phone to laptop.

Would love your feedback!
