I built a lightweight tool to hide private windows (like Slack/Discord) when sharing your screen on Zoom/Teams. Hey Product Hunt! 👋 I'm the creator of VeilCast. As a remote worker, I was always terrified of accidentally leaking a private Slack message or sensitive file while sharing my screen on Zoom. So, I built a solution. VeilCast is an ultra-lightweight (400kb) Windows tool that completely shields specific windows from screen capture.
