Keyviz is a free, open-source utility developed by Rahul Mula that renders every keystroke on screen in real time, letting educators, streamers, presenters and tutorial creators show exactly which keys they press without interrupting their workflow. Designed for the “Presentation” category, the program overlays a small, customizable panel that pops up briefly whenever a key or combination is struck, making it ideal for live coding sessions, software demonstrations, remote lectures, gaming walkthroughs, accessibility testing, or any scenario where invisible keyboard actions need to be communicated to an audience. Users can choose between minimal badges, colorful animations, or sleek dark-mode pop-ups, adjust position, size, duration and opacity, filter out everyday typing noise, and even limit display to specific hotkeys so only shortcuts appear. The lightweight agent runs in the background with negligible CPU load, supports multi-monitor setups, and respects privacy by processing everything locally without network calls. Since its initial release the project has iterated through three public versions, culminating in the current stable build 2.1.1 which refines animation timing, adds high-DPI awareness, and improves compatibility with Windows 10/11 input hooks. Portable archives and a signed MSI installer are provided, allowing deployment on personal machines or corporate imaging systems without licensing concerns. The software is available for free on get.nero.com, with downloads supplied through trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation alongside other applications.
