SteamPen

Steampen Screen Drawing Software is a professional and powerful screen annotation tool. It supports diverse annotations on transparent screens, allowing users to draw geometric shapes like straight lines, arrows, squares, and rectangles, as well as add numbered annotations (e.g., 1, 2, 3). All annotations can be directly saved as images. Its unique brush tool, designed with a transparent background, ensures annotations never obscure the underlying video playback. This feature makes it ideal for scenarios like gaming livestreams, video broadcasts, or billiards livestreams, enabling hosts to provide real-time on-screen guidance and enhance audience interaction.
