FAQ

Questions franc owners ask.

  • 01

    Why is this better than asking Claude to detect the language?

    LLMs often hallucinate languages for short strings or names. They also struggle to provide standardized ISO codes reliably. This engine uses mathematical N-gram analysis (the same technique behind Google Search language detection) to deterministically map text to one of 400+ ISO 639-3 codes.

  • 02

    What does it mean if it returns 'und'?

    'und' stands for Undefined. It means the text is too short, mostly numbers, or too ambiguous to confidently map to a single language. This is a feature. it prevents your routing logic from making false assumptions.

  • 03

    Can I force it to choose between specific languages?

    Yes. Pass an array of ISO 639-3 codes to the 'only' parameter (e.g., ['eng', 'por', 'spa']). The engine will only calculate probabilities within that subset.
