Hello, I am looking for a way to bulk add alt text to thousands of images that are Not already in word-press.

So far have landed on clarifai, and ideally would love a way to use AI / machine learning to use object detection or patterns for relevant tags, but so far its been a painful process.

At this point Id be open to any software that would allow me set alt text based on file name and an identical set of tags (per folder of images) that would be relevant to each photo-shoot (luckily we do have the images all organized into folders already or this would be impossible).

I would even be okay with a decent photoshop plug-in if one exists though I havent been able to find one. I though I has used batch photo or handbrake in the past for this but It turns out my memory was incorrect and I can not find which software I used.

Prefer a mac solution but can run windows as well if needed in this scenario.

Thanks in advance, any suggestions appreciated!
