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.
