There are three flags in chrome://flags currently required to see the Projector app: Enable Projector, Enable Projector annotator, and Enable Projector exclude transcript feature.

Some of the apps created for Chrome OS also work on other platforms, such as the new Calculator, but it's not clear if Projector will be functional outside of Chromebooks. The new application seems like it's built primarily for use in education, where it could be helpful to teachers recording lectures or tutorials, or students recording remote presentations (with a slideshow running full-screen, for example). Projector will also apparently save recordings to Google Drive - hopefully saving to local storage will still be an option, because screen recording files can take up an awful lot of storage, especially full-resolution recordings on large screens.

There will be an option to include your own camera in the corner of the recording (similar to the screen recorder on Samsung One UI and other Android skins), and the app will generate a searchable transcript of your speech.
