From the developer
Valerio Monti's own description of Auto Alt Text, lightly tidied.
This plugin implements the automatic creation of alt text for images uploaded to the media library. The alt text is generated at the time of uploading the image and it is also possible to generate the alt text for images already present in the media library.
To generate the alt text, you can choose to use the artificial intelligence of OpenAI, Anthropic Claude, Google Gemini or Azure, or decide if you simply want to copy the title of the article where the image is uploaded or the name of the image.
Clearly, using artificial intelligence will allow for a more accurate and useful alt texts.
