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.

Basic Annotation Features:

• Extensive customization options for lines, circles, and shapes, including adjustable colors and thickness.
• Free tools like screen clearing, erasers, undo/redo annotations, and intuitive shortcuts.

Advanced Professional Features:

• Whiteboard/Blackboard Modes: Adapt to different writing scenarios.
• Image Library: Import pre-edited images, zoom, resize, drag, and pre-annotate them for live demonstrations.
• Timed Clearing & Repeating Annotations: Automatically remove or loop annotations to suit dynamic workflows.

Enhanced Usability:

• Hold Shift while drawing lines to lock them at 90° or 180° angles.
• Hold Shift while drawing rectangles to create perfect squares.

Perfect for livestreamers, educators, and professionals, Steampen combines precision with seamless interactivity.
