Introduction 

What does it do? 

Ai3 Alt Text (|extension_key|) is a TYPO3 extension that automates the creation of accessible alternative texts for images stored in the TYPO3 file storage. It communicates with the ZAK-AI REST API — provided by wegewerk/ai3_core — to generate descriptive, language-aware alt texts using a vision-capable AI model.

The extension adds a dedicated backend module under File > AI3 metadata with two views:

File metadata view
Lists all images in a selected folder. For each image the current alt text, AI-generated suggestion, usage count, and available actions are shown. Editors can generate alt texts individually or in bulk, review suggestions, and approve or edit them before they are saved to the file metadata record.
Folder view
Shows the sub-folder tree of the file storage. Editors can accept all pending AI suggestions across an entire folder hierarchy with a single click.

In addition, a FormEngine field control button is injected into the Alternative Text field of the file metadata edit form, allowing editors to queue a single image for alt text generation without leaving the record editor.
