Questions
Can ChatGPT control PixelSnap?
On a Mac with BCD, yes, through the app's window: ChatGPT can open PixelSnap, read the buttons and text it shows, press buttons, type and pick menu items. How far that goes depends on how much of its window PixelSnap exposes to macOS accessibility.
Does this work on Windows?
No. BCD controls app windows only on a Mac. On Windows and Linux it works with files and commands.
Is it safe?
A new computer starts read-only. Controlling the screen and apps is turned on per computer, and macOS asks once before BCD may control apps.
Try it on your computer
BCD connects ChatGPT, Claude and other AI apps to your own Mac, Windows or Linux computer. One computer is free, with 20,000 tool calls a month and no card.
