If I'm understanding your question correctly, it's neither! It's something you'd draw on with your mouse or trackpad on a laptop. We also have other tools you can use to make it easier to tutor math (e.g., ability to add text and shapes to the whiteboard, ability to upload photos of homework, etc.).

In the future, we actually do plan to add audio to the platform as an optional feature that students can turn on. Most students prefer the text-based communication of our current platform, but there are definitely some who would use audio if given the choice. We still need to think through how to get mutual buy-in from both the student and volunteer in that session as well as whether we want to do additional background screening for volunteers who want to use that feature.
