It saves me a lot of time of adding alt tags to my images.

I've been using AltText.ai for months now and it's saved me and my team 100's hours on filling in ALT and TITLE tags for the many, many images we have on our websites. And the descriptions are always spot on. If you're like us where ALT tags are almost always fogotten entirely or until the last minute, I highly recommend you use this awesome tech.
