Hook uses scripts to integrate with other applications using AppleEvents and other inter-app communication systems, such as x-callback-url.

It is possible to create integration scripts for many unsupported apps and if the app doesn’t have the necessary scripting support or inter-app communication, you can always contact the developer about improving their app to make it compatible.

It is also possible to customize how Hook integrates with an application by writing a new script for it. Some examples are available:
– DEVONthink
– Things
– Xcode
