Localize your TYPO3 XLIFF faster and smarter with AI-driven translations, freeing you to focus on growth. Pick your AI model, select your files, and publish to Crowdin, all from the TYPO3 backend.
AI-Powered XLIFF Translation, Native to Your Backend
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 the AI models you trust, and handles batch XLIFF localization with Crowdin sync, without forcing you into external translation management platforms. You keep control. You choose the AI engine. And you can localize an entire extension in minutes, not weeks.
Download free. No card Required.
Just see if it works for you - in your real TYPO3 project, not a demo.

Your Data. Your Server. Your Rules.
T3AL runs entirely within your TYPO3 instance. No data leaves your server unless you send it to your chosen AI provider, and you control which provider that is. 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.
