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.

 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.
