Keyviz is a free and open-source tool designed to visualize your keystrokes and mouse actions in real-time. Its main purpose is to give your audience a clear view of your inputs during any screen-share, making it easier to highlight shortcuts and improve engagement.

Key features include visualizing every keyboard and mouse action as it happens, displaying mouse clicks and scroll wheel movements alongside the cursor, and offering input filtering to show only relevant shortcuts or hotkeys. The tool provides endless customization options, allowing users to tweak keycap style, size, color, border, icon, and almost every aspect of the display.

Keyviz works by processing all keystrokes locally on your device, ensuring privacy as no data is sent over the internet. It includes preset entry and exit animations for how inputs appear on screen, and the Pro version offers additional animations, styles, and animated mouse indicators.

Benefits include enhanced clarity for viewers during presentations, tutorials, or live coding sessions, leading to better understanding and engagement. Use cases involve screen-sharing scenarios where demonstrating keyboard shortcuts or mouse actions is essential, such as in software tutorials, educational content, or live streams.

The tool is targeted at users who need to showcase their inputs transparently, including educators, developers, and content creators. It is available for Windows and macOS platforms, and being open-source, it is community-driven and free for everyone, with optional Pro features for advanced customization.
