ai_filemetadata – AI-Generated Alt Texts for Accessibility

Automated creation of descriptive alt texts for people with visual impairments

The Problem: Missing or insufficient alt texts exclude people with visual impairments from key information.

In many cases, images are either missing alt texts or are only assigned rudimentary (SEO-focused) descriptions. This does not meet the needs of users who rely on screen readers. Descriptive alt texts are essential to convey the content of an image and are legally required by the European Accessibility Act (EAA) (EU Directive 2019/882) for websites. Missing or insufficient alt texts not only reduce user experience but may also result in legal consequences.

Creating alt texts is often the responsibility of editors. Writing an appropriate description for each individual image in a CMS is a time-consuming task.

Our Solution

With the TYPO3 extension ai_filemetadata, we offer a smart solution: The extension uses OpenAI's service to analyze image content and generate alt texts. These suggestions can be reviewed, accepted, or modified by editors. This is significantly streamlining the process.

Open Source Availability: Compatible with TYPO3 Version 12 and above (requires PHP 8.2).

Seamless Integration in TYPO3:

  • Create alt texts directly within the Filelist module.
  • Automatically generate alt texts when new images are uploaded.
  • Option to manually create or adjust alt texts in the Filelist module.
  • Multilingual Support: Generates alt texts in all active languages of the TYPO3 instance.

Important Information

  • Data Privacy: Since images are transmitted to an external service, it is essential to ensure compliance with data protection policies and image licensing before use.
  • API Usage:An OpenAI API key is required. Using the API incurs minimal costs. For example, processing 100 images cost less than 1 Euro in our tests.
