It's a very basic plugin which does its job, but it definitely needs to have an option too choose the language in which the alt text is generated.

This plugin has a good UI with all the features and options that you need, but nothing more. It doesn't want to sell you some "Premium" features, but lets you enter your own API key. Highly recommended!

Great and easy to use plugin. Thanks for this.I just wished for one little improvement.The additional prompt, which I can write while in bulk edit, can that be saved? So I do not need to enter it again?Or maybe let us define a user prompt in the Settings -> Media, where we provide our API key. That would be awesome.
