It's a feature of OS X, not the individual apps. When you install a
compatible tablet, Ink will be available in System Preferences. See Mac Help
on the topic for more details:

Writing text with your graphics tablet
If you have a graphics tablet and stylus, you can use Ink technology to
write text that your computer recognizes and turns into words. You can write
anytime you're using your stylus, in your own handwriting. You can also use
Ink to draw a sketch and insert it in any document that can display
pictures.
With Ink you can use your stylus to write menu commands and keyboard
shortcuts, allowing you to control your computer without using the mouse or
keyboard.
When you have a Wacom graphics tablet connected to your computer, and the
Wacom tablet software is installed, the Ink icon appears in System
Preferences.
To find out more about Ink, click the Ink icon in System Preferences and
turn on handwriting recognition. Then choose "Open Ink help" from the right
side of the Ink toolbar.
