It’s had this for a few years. Microsoft has its Office Lens both as a freestanding app, and built in to the combined Office Android app. Adobe has a pretty good scanning app too, though I’ve moved away from Adobe anything. All of these companies are chasing after corporate clients who might already have the app installed as part of their enterprise subscription. Probably helps with locking in if employees are used to opening the Drive app for their scanning, as opposed to a freestanding app.
