I built a Mac app that shows your Zoom call only the windows you pick, so nothing private leaks while you share your screen

Scrim is my side project: a Mac app that shows your video call only the windows you pick. Why I built it Every time I share my screen on a call, I get two bad options. Share the whole screen, and the call sees everything: Slack and iMessage notifications sliding in, my other tabs, the files on my desktop.

AI 分析

痛点:共享屏幕时,要么整屏共享导致通知、私人标签页和客户信息泄露,要么只共享单窗口导致切换应用时手忙脚乱、演示被打断

目标用户:需要频繁在 Zoom/Meet/Teams 上做演示的 Mac 用户:销售、顾问、自由职业者、远程工作者、教师

证据:Once, a calendar alert with another client's name popped up in the middle of a client demo. Since then I spend shared calls watching the corners of my screen instead of talking. / So I kept sharing the whole screen because switching was too slow, and kept getting caught.

变现:Mac 买断制($15–30 一次性授权)加免费试用 7 天;后续可加 Pro 版订阅(多窗口布局、录制、团队批量授权)

MVP:用 ScreenCaptureKit 采集用户勾选的若干窗口,合成到一个虚拟"Share Me"窗口中,供会议软件共享;支持快捷键切换窗口集合、简单画笔和激光笔;两周内可做出可用的单机版

竞品:macOS Sequoia 内置 Presenter Preview、Zoom 自带共享白名单/仅共享部分屏幕、mmhmm、Presentify、ScreenBrush、CleanShot X(截图/录屏附带)

摘要:作者发布了一款 Mac 应用 Scrim,让视频会议只看到用户挑选的窗口,避免整屏共享时弹出的 Slack、iMessage 通知或客户日历提醒泄露隐私。痛点来自他本人在客户演示中被日历弹窗曝出另一位客户名字的真实经历,并指出单窗口共享切换太慢、无法并排显示两个窗口。帖子只提供个人经历,没有提到价格、收入或其他用户的付费反馈,且 macOS 系统与 Zoom 已内置相似功能,竞争空间有限。
