Is the AI description accurate?

It is good at what is in the picture in general terms, and it does not know names of people or products. Treat it as a draft that a person reads and corrects.

Are the images uploaded?

No. The describing model runs inside your browser; press "Network" in the bar to see for yourself.

Write alt text for your images

Every image on a site needs a description for people who cannot see it and for search engines. With dozens of images the work stalls; a drafted line gets it moving.

Open the alt text generator

Steps

Drop the images on "Alt text generator". The first time, the description model is fetched once into this browser.
Choose the language and press "Describe". A one- or two-sentence alt text appears.
Read the draft and add what only you know: names, products, context.
Copy it into your HTML or CMS. To describe many images at once, use a Pass.
