nt-lingua — Translation for TYPO3

Real-time translation, Plain Language (Einfache/Leichte Sprache) and native SEO overlays for TYPO3, powered by DeepL or any AI provider via nt-ai.

  • Real-time translation

    DOM-based translation into any language with a single click. No page reload, glossary support, MutationObserver for dynamic content.

  • Plain Language

    Switch page content to Einfache Sprache (simple language) or Leichte Sprache (easy language) on demand, powered by AI.

  • SEO-native overlays

    Generate real TYPO3 l10n overlays for strategic languages — server-rendered, indexable, with automatic hreflang.

  • Shared cache

    All three features use one cache table (tx_ntlingua_text_cache). Repeated requests cost zero tokens.

  • Glossary

    Force or exclude specific terms per language. Works for DOM translations and AI transforms.

  • Cache warmup

    Pre-fill the cache via CLI before users request translations. Scheduler-ready.
