OCR text selection is available via Google Lens. What I'm talking about specifically is the ability to select out text from app pages where text selection is not usually possible. For example, say an app had button text or an embedded image, it is not possible to select these unless the app developer made those selectable. In Pixel devices, it's possible to go to the recent apps menu, and select these unselectable texts via OCR. This feature was previously available to all devices via Google Now On Tap but has since been limited.
