AI Alt Text helps you generate, review, and approve alternative text for images in the TYPO3 file system. You can generate AI alt text in two ways:
  1. AI Alt Text module — AI Accessibility → AI Alt Text. Review missing alt text by folder, generate drafts for selected files or a whole folder, then approve them in one place.
  2. File List (Media) — open an image and generate alt text one by one image, or use Mass AI File Meta for a folder (including multilingual options and Scheduler processing).
Both paths write into TYPO3 file metadata. Use the module for coverage and review; use File List when you are already editing specific files.

Steps — AI Alt Text module

  1. Configure an AI provider in AI Foundation → AI Providers.
  2. Open AI Accessibility → AI Alt Text.
  3. Select a fileadmin folder in the left tree.
  4. Check tiles such as Missing alt text and Awaiting review.
  5. Filter to Missing or Used only if you want to prioritise.
  6. Select images, then click Generate alt text (or use Generate on one row for a single image).
  7. Review each draft, edit if needed, then Approve or Save.
  8. Mark true decoration images as decorative (empty alt on purpose).
  9. For large folders, use Add to Queue / Queue folder for AI alt text, then process the queue with Scheduler / nst3aa:bulk:metadata.

​
What Decorative means

Decorative means the image is not meaningful content. T3AA stores empty alternative text on purpose so assistive technology can skip it.
  • Marked decorative — intentionally empty (correct for pure decoration)
  • Missing — a meaningful image that still needs alternative text
Do not mark informative photos, meaningful icons, or charts as decorative.

Module overview

​
Folder and language

  • Folder tree — counts and the table follow the selected folder
  • Language — All languages or one language
  • Refresh counts — reloads metadata only (does not call AI)
  • Queue folder for AI alt text — queues the folder for bulk generation

​
Filters and bulk actions

Filters: All, Missing, Drafts, Decorative, Used only. Bulk bar (after selecting rows): Generate alt text, Approve drafts, Mark decorative, Add to Queue. Row actions include Save, Generate (one image), Queue, Decorative toggle, and Edit (TYPO3 file record).

​
Steps — File List (one by one image)

  1. Open File List and select a folder.
  2. Edit an image’s metadata.
  3. Use Generate AI Alt Metadata, choose the generator (TextAlt.ai or Vision API), then Generate.
  4. Review and Save.

​
Bulk metadata (Scheduler)

  1. In File List, select the folder.
  2. Use Mass AI File Meta.
  3. Choose missing-only or override existing metadata.
  4. Select language options when offered.
  5. Process with Scheduler or nst3aa:bulk:metadata.
  6. Review and approve drafts in AI Alt Text / File List.

​
Important notes

  • Drafts are not finished until someone approves or edits them.
  • Opening the inventory reads metadata only; generation needs AI Foundation provider configuration and feature access.
  • A valid T3AA license is required for generation.
