AltText.ai

AltText.ai is a service that automatically generates alt text (the alt attribute) for images using artificial intelligence. It analyzes each visual and produces a relevant description, useful both for search rankings and for the accessibility of visually impaired users.

What is AltText.ai for?

You upload images, or connect your site, and the tool writes a descriptive alt text, with support for multiple languages and the option to include keywords. It integrates with WordPress, Shopify, Contentful, and via an API, letting you automate alt tags across an entire catalog. The target audience: e-commerce businesses, publishers, and agencies with hundreds of undescribed images who want to gain on SEO and compliance alike.

AltText.ai or writing it by hand?

Writing alt text manually stays more precise on a handful of key images. But as soon as volume grows, automation saves a considerable amount of time, at a quality that's more than sufficient for most visuals. Paired with a tool like Semrush for auditing, it's a real accelerator for cleaning up undescribed images.
