Large files straight from one machine to another, in the browser
A 32 GB file sent through the browser, with no account, nothing to install, and nothing left sitting on a server. Open the page on a laptop and on a phone, and the two talk directly to each other. Paste a piece of text or an image from the clipboard and send that too.
And back. Windows, Mac, Linux, iPhone, Android.
Paste and send, with no file to save first.
Nothing passes through storage, and nothing is left behind.
