Add-ons are extensions to SMART Notebook software created by SMART Technologies and by third-party software developers.
SMART Notebook software includes the Activity Builder add-on (see Creating a matching lesson activity) and the Alignment Tools add-on (see Aligning objects). You can install other add-ons from the SMART Exchange website to add specialized features to the software. In addition, you can manage all installed add-ons using the Add‑on Manager.
