Then make it a generic image editor. What we have now is: an editor but for screenshots, an editor but for selfies, an editor but for cat photos, each with its own cloud storage which leaks (or spills) data once a year and which data is also being processed by the app owners in ways you’d be disgusted about.

There’s a screenshot functionality in the OS and there’s a Share button which should work just as fine and be way more secure.

The shot->image-process->save->share cycle takes user time, and is an inconvenience that some people will even pay money to avoid. Since we're talking about screenshots, we're actually talking about typically, developers, tech writers and marketers who are automating their day-to-day workflow.

Shot - share to your fancy shmancy editor that puts a phone frame around it - put a frame around it - save somewhere.

Here, simplified that for you.

You can totally make an app that streamlines this and doesn’t cast doubts on its privacy hygiene at the same time.

I think the person you are replying to is saying that the entire flow is a single action: you hit screen shot, and the screen shot is taken, edited, and shared to some configured entity, in one step. Seems pretty obvious to me why a single step that doesn’t remove you from app flow would be waaaayyy more useful than needing to use any other apps to complete the job.

Actually, other than being humorous, you just said, do it the way I want you to without any understanding of why a user may not want to do it that way.

But third party app can be more flexible. For example, I used a app that can let you easily crop a part of screen, then you can edit, image search, share, OCR than translate and many things just in a pop-up.
