Frequently Asked Questions -------------------------- [ More FAQs ](https://t3planet.de/en/faqs) Which TYPO3 versions are supported? T3AA runs smoothly on TYPO3 major LTS versionnewer, ensuring longevity and security for both current and upcoming enterprise projects. Will you help me to install it? Simply activate the license key, install the T3AA extension in the backend, insert your preferred AI‑provider keys, and start generating alt‑text or audio within minutes—no additional setup wizards required. Does T3AA guarantee WCAG compliance? 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. Is data sent outside the EU? No, all the data will be within your TYPO3 instance. What AI engines are included? 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. Can I bulk‑process existing media? Absolutely. Select any folder inside File‑list, hit “Generate All,” and watch hundreds of images receive descriptive metadata and alttext without manual touchpoints. Any recurring fees? 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. What are the Offline environments? Generation jobs can queue for later or connect to an on‑prem inference server, ideal for staging sites, intranets, or high‑security networks. What about Core Web Vitals? While T3AA optimises filenames and metadata, it does not monitor vitals; pair with your favourite performance tool for full coverage. Is support included? You get detailed docs, a dedicated Slack channel, and priority ticketing. Enterprise customers can add a formal SLA for mission‑critical use cases. Can I swap AI vendors later? Yes. Engines are decoupled; toggle between OpenAI, ElevenLabs, or alttext.ai without reinstallation or data migration hassles. ![](data:,) Meet Our AI Consultant, Jürgen! ------------------------------- Looking for guidance with TYPO3 AI?
