Screenhero founding engineer here. I've been working with the CoScreen team for a few months now, and I am incredibly impressed with the product and the team. They've taken our idea and really pushed it forward—it's not collaborative screen sharing anymore, it's a shared desktop which anyone can drop a window onto. (I'm only a little embarrassed we didn't imagine this UX back in 2013).

If you've never used something like this before, think back to a Zoom call you've had recently where someone else was sharing their screen, and you really wish you could have just driven for a moment instead of dictating instructions. Or just shared a window on your own desktop to illustrate a point. CoScreen lets you do all of this seamlessly.

Anyway, absolutely endorse this product.
