ALTerator has been a fantastic addition to our workflow. The app generates highly accurate, context-aware alt text for product images, something that would otherwise take significant manual effort to produce consistently across a catalog.

The AI performs extremely well and produces descriptions that are relevant to the product and image content rather than generic filler text. The tool is also very configurable, allowing you to tailor output so it fits your catalog and workflow.

Just as important, the pricing model makes it cost effective to run across a full product catalog without hesitation.

Customer support has been outstanding. The team is responsive, helpful, and clearly committed to improving the product. Even though the app is relatively new, it already performs extremely well and the developers are quick to respond to feedback and feature requests.

If you care about accessibility, SEO, and maintaining a clean, well structured product catalog, ALTerator is an easy recommendation.
