Welcome to Screenbites, a lightweight desktop tool that helps you share only part of your screen, highlight your cursor, and draw live during meetings, demos, or online classes.

Screenbites lets you share a cropped area of your screen instead of the whole display. It runs as a transparent overlay, compatible with any screen-sharing app.
