Frequently Asked Questions

Does everyone see my markups in Bullclip™?

In Bullclip™ you can choose to markup your draft layer or to push to the public layer. You can work on your draft layer for as long as you like, and have it sync between devices until you're ready to push to the public layer.

Is this different to a document management system?

Bullclip™ hosts your documents in the cloud. Organize your content with tags and a version control mechanism. Bullclip™ doesn't have to replace your current working system—and allows you to organise content the way you want.

Will this work on any Windows 10 PC?

Yes! Bullclip™ is a Windows 10 Universal Application, which means that any Windows 10 PC can use it (including Surface Hub). Some devices will make better use of Bullclip™'s digital inking and touch-friendly design, such as the Microsoft Surface.

Is Bullclip™ really 'real-time'?

Absolutely. If your project manager in Seattle is marking up a drawing in the public layer, your subbie in Orlando and design engineer in Colorado will see everything as it's written.
