@exchgr @radicalrobit @MonaApp But (I think) only *before* the image is in the compose window? If I long press on the images in your post, yes, I can select text. But if I long press > share to Mona, once the image is in the composer I only get the options to add alt text or remove.
Auto-detecting text and adding it to the alt was (is?) a great feature of Metatext.
