Altomatic.ai is a tool that uses artificial intelligence to automatically generate descriptive alt text for images and optimize them for web performance. It aims to help website owners improve accessibility, SEO, and page load times without manual effort.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on bulk processing of existing image libraries, and improves accessibility and SEO simultaneously caught me off guard. still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: sEO-friendly metadata output and automates time-consuming alt text writing. Where it lags: limited control over compression settings in some plans. On balance the feature set — especially aI-generated alt text for images — justifies the 4 stars for our use case.

Use it every day

Honestly didn't expect to like it this much. Accessibility compliance support is exactly what I needed, and reduces image file sizes for faster loading. I do wish aI-generated alt text may need manual review, but I reach for it almost every day now and it just clicks.

Solid for our team

We rolled this out across the team last quarter and automates time-consuming alt text writing. Automatic image compression and optimization fits neatly into how we already work, and aI-generated alt text for images removed a step we used to do by hand. but it has held up under daily use.

Solid for our team

We rolled this out across the team last quarter and improves accessibility and SEO simultaneously. Accessibility compliance support fits neatly into how we already work, and accessibility compliance support removed a step we used to do by hand. AI-generated alt text may need manual review, which is the main caveat, but it has held up under daily use.
