Very helpful plugin in generating alt texts. Although it needs to always to review them for errors. Many times the text must corrected but it speeds the all process writing alt texts much more than doing it yourself. Definitely recommended!

We discovered AltText.ai through AppSumo, and I must say we’re incredibly impressed with the quality of the output. The AI does an excellent job of integrating relevant keywords into the assigned pages, and the results have been spot on. We’ve tested it across a few of our sites, and the experience has been absolutely seamless. We’re excited to see how the plugin continues to evolve and wish your team all the best. You’ve earned a lifetime user in us here at WP Codeus!

Disappointed Alt Text AI does nothing if your pics are AVIF format. I’ve converted most images on my site to AVIF (from jpg) since the file size is usually 90% smaller than jpeg (after compression).Webp is much better than jpg. AVIF is way better than webp. I look forward to when Alt Text AI can see an image even if it’s not in jpeg format (or png).

This plugin is exceptional and very easy to use. I am a photographer and I have a lot of images on my site. I was able to update all my Alt tags very easily, and above all the artificial intelligence used recognizes and describes my images perfectly, even complicated ones. The huge time saving is well worth the investment, I recommend 200%. In addition, the support responds very quickly and is very efficient.
