Frequently asked questions

What is Casper?

Casper is a small assistant window for Mac that only you can see. It stays hidden from screen share, recordings and screenshots, so you can keep a chat, notes or docs open while you present, and screenshot your screen straight into chat when you need help with what's on it.

What do I need to run it?

macOS 14 or later.

Is Casper cheating?

No. Casper is an assistant tool. You're responsible for how you use it.
