T3AA – All in One TYPO3 AI Accessibility Extension

AI Accessibility for TYPO3

Bulk  AI Alt Text Live WCAG Audit AI Metadata Text‑to‑Speech Voiceovers

The complete TYPO3 AI extension add‑on for bulk alt‑text, live accessibility audit, easy language, audio, and voiceovers, built for effortless accessibility. No SaaS. No recurring fees. Just AI that makes your site inclusive, right from the backend.

AI-Driven Accessibility, Native to Your Backend

 If you've ever stared at hundreds of images missing alt-text, or tried to make your content listenable without a recording studio… yeah. That's a problem. T3AA fixes that in a very TYPO3 way: it lives inside your backend, connects to the AI engines you trust, and handles alt-text generation, live accessibility audit, easy language, audio narration, and voiceovers, without forcing you into a SaaS model. You keep control. You decide the AI provider. And you can continuously improve accessibility using built-in audits and bulk processing.

Download free. No card Required.

Just see if it works for you — in your real TYPO3 project, not a demo.

 T3AA runs smoothly on TYPO3 major LTS versionnewer, ensuring longevity and security for both current and upcoming enterprise projects.

 T3AA automates repetitive tasks like alt‑text and audio creation, dramatically reducing effort, but final human audits remain essential for full WCAG certification and legal peace‑of‑mind.

No, all the data will be within your TYPO3 instance.

 Vision and TTS via OpenAI, alttext.ai keyword tagging, and ElevenLabs’ lifelike voices—choose per task or even mix‑and‑match on the fly for best results.

Absolutely. Select any folder inside File‑list, hit “Generate All,” and watch hundreds of images receive descriptive metadata and alttext without manual touchpoints.

 The extension itself is a one‑time license, if you choose Lifetime license. You only pay your chosen AI providers for actual usage, often pennies per request.

 You get detailed docs, a dedicated Slack channel, and priority ticketing. Enterprise customers can add a formal SLA for mission‑critical use cases.

Yes. Engines are decoupled; toggle between OpenAI, ElevenLabs, or alttext.ai without reinstallation or data migration hassles.
