Keyviz: Let Your Audience See What Keys You Press in Tutorials
One-sentence solution: When recording software tutorials or demos, how does your audience know which shortcuts you pressed? Keyviz shows every key you press on screen.
If you’ve ever recorded software tutorials or demo videos, you’ve likely faced this problem: you press a bunch of shortcuts, but the video doesn’t show keyboard operations, so the audience has no idea what you did.
Keyviz bridges this information gap.
What Is Keyviz?
Keyviz is a real-time keystroke visualization tool. When you press a key on your keyboard, a corresponding key display appears on screen — press Ctrl+C, and “Ctrl+C” appears. The display lingers for a moment then fades out.
The problem it solves: Showing keystroke actions in screen recordings so viewers know what keys you’re pressing.
