AI Alt Text Generation automates one of the most critical yet time-consuming aspects of accessible content, ensuring every asset is compliant, contextual, and ready for use. Aligned with the latest WCAG 2.2 AA guidelines, this feature generates accurate, descriptive alt text that is stored directly on the asset as metadata, improving accessibility and usability across your DAM. By removing the need for manual entry, AI Alt Text Generation helps teams scale accessible content with confidence while maintaining consistency and compliance.

Prerequisites

Before taking advantage of AI Alt Text Generation, the following should be confirmed:

• Users have the appropriate Roles (DAM > Add Assets) to generate asset alt text.

How It Works

When an asset is uploaded, the AI model identifies key features like objects, people, colors, or places. It uses its training data (millions of images it’s learned from) to recognize these elements. Based on this analysis, Lytho recommends alt text that is a contextual match.

Lytho's AI model is pre-trained. We will not use customer data to further train the model. 

Using AI Alt Text Generation

Select an asset, from the Asset Manager or Waiting Room, and navigate to the GENERAL tab.

Within the Asset Manager, you can select the asset in two ways. The first option is by clicking the circle in the top-left corner of the image, which opens the asset menu in the bottom-right. 

The second option is by clicking the center of the image to open a larger preview. Select All Details to access the GENERAL tab.

Within the GENERAL tab, click Generate alternative text. AI will automatically create alt text that aligns with WCAG AA 2.2 accessibility standards.

Once the alt text is generated, review it and either keep it as-is or edit it to better match your brand voice or provide additional context. Be sure to save your changes by selecting the checkmark icon.
