The terms passive and active stylus refer to how the stylus interacts with the device.

Passive styluses do not use any electronics or connectivity with the device to interact with the touchscreen; they typically use a capacitive tip (usually rubber) to mimic the input of a finger on the screen. Whereas active styluses can connect to the device (often via Bluetooth) in addition to having a capacitive tip. 

Kami will recognize when you are using a capacitive stylus and will automatically enable touch scrolling. A small pop-up will appear at the bottom of the page to notify you of this (refer to screenshot below). To revert this change, just select 'Disable'.

Touch scrolling lets you scroll the page with your finger whilst drawing and annotating in Kami using your stylus. The following Kami tools can be used free-hand with an active stylus: 

We also support the Apple Pencil on iPads. When you use Kami in the Chrome app on iOS, it will auto-detect the input. You can then use your Apple Pencil with the Kami tools as mentioned above.
