Testimonials

Built for people who present live

A few of the workflows where a clean second-screen view matters most.

I teach with slides on one screen and my notes on the other. twindow lets students see only what I intend to present without exposing the rest of my desktop.

Elena M.

College Lecturer

During client reviews I need one clean view for the room and a separate working setup for myself. twindow made that split feel deliberate instead of improvised.

Marcus T.

Project Manager

I often present dashboards while keeping private models and messages off-screen. twindow gives me a much cleaner handoff to the external monitor.

FAQ

Common questions

What are the system requirements?

twindow requires macOS 13.0 (Ventura) or newer and supports Apple Silicon Macs only (arm64: M1, M2, M3, or M4).

Is it screen mirroring?

Not full-screen mirroring. twindow is selective duplication of specific application windows.

Does it record my screen?

No. twindow does not record your screen. macOS requires apps to request Screen Recording permission in order to access the contents of a window. twindow uses this permission only to live-mirror the selected window to a twindow on another display. Nothing is recorded, stored, or saved to a video file.

Does it capture keystrokes?

No. twindows are read-only and do not pass input through.

Will it work with Zoom or OBS?

twindow helps you prepare what to share on a second monitor, but it is not a Zoom or OBS plugin. We recommend using twindow in conjunction with these tools to create a seamless presentation experience.
