Join thousands of teams making their images accessible.
“We had 1,200 product images with zero alt text. AltText AI processed all of them in 20 minutes. Our Lighthouse accessibility score jumped from 62 to 94 overnight.”
Sarah Chen
Ecommerce Director, ModeMaison
“I build 30 client sites a year. AltText AI is the first plugin I install on every single one. It's saved me hundreds of hours of manual alt text writing.”
Marcus Rivera
WordPress Developer, River Sites
“The EAA deadline was terrifying until we found this. 50 free images a month means our small blog is compliant forever. The quality is indistinguishable from human-written alt text.”
Elena Kowalski
Content Lead, EU Policy Watch
“As a screen reader user, bad alt text is my biggest frustration online. AltText AI consistently generates descriptions that are actually useful — not just 'image' or 'picture'.”
Devon Williams
Accessibility Advocate
“Google Image Search traffic up 40% in two months. The alt text is genuinely good — descriptive, keyword-aware, and reads naturally. Better than what I was writing manually.”
Priya Mehta
SEO Specialist, GrowthFunnel
“The API is a joy to work with. Clean docs, fast responses, sensible error handling. We integrated it into our headless CMS in an afternoon.”
