If you've ever manually translated XLIFF files label by label, copied strings between spreadsheets,
or waited weeks for external translators to return .xlf files for a single extension… yeah. That's a productivity black hole.
T3AL fixes that in a very TYPO3 way: it lives inside your backend, connects to DeepL, OpenAI, Gemini or Google Translate with your own key, and
localizes your XLIFF files with Crowdin upload, without forcing you into external translation
management platforms. You keep control. You choose the provider. And you can localize an
entire extension in minutes, not weeks.

Use EU-hosted models, self-hosted Ollama, or commercial APIs. All translations stay in your TYPO3 backend until you explicitly publish to Crowdin. No SaaS intermediary. No external dashboards storing your translation files. Your backend, your data, your rules.
