I'm looking for an mobile app with an accompanying cross-platform desktop companion (or Chrome extension) to allow the sharing of clipboard contents across a range of devices.
Right now, to transfer short bits of text (e.g. URLs) from one device to another, I use Pushbullet. This is a workable solution, but I'm looking for something a bit more seamless, so I can CTRLC a URL on my Android device and paste it into the address bar on my Xubuntu machine. In short, I want a unified clipboard that's shared across devices.
More platforms are definitely preferred because I often use a range of devices that run Chrome OS, Xubuntu, Windows, OSX, Android, iOS amongst others. It's going to be difficult to find a solution that works across all, so something that works across 3 of them or works on mobile as well as Google Chrome is fine.
Holroy has graciously pointed out below that Pushbullet actually supports this, and I can confirm it works brilliantly once you enable it for each of your devices.
