Best AI for translation

Google Translate gets the words right; AI gets the tone. The right model preserves register (formal vs casual), handles idioms instead of literal-translating them, and asks when context is ambiguous.

Our pick
Claude Opus 4.7

Best at preserving tone + register, especially for formal/technical content. Will ask for context on ambiguous source.

Sample prompt to try

Translate this customer support email to Brazilian Portuguese. Keep the warm, slightly informal tone — not robotic. [paste email]

What to look for in any model

  • 1Specify the register: "formal business," "casual," "literary" — translation isn't a single style
  • 2For technical content, paste a glossary of preferred terms in the prompt
  • 3For rare language pairs (e.g., Vietnamese → Welsh), don't trust either model — verify with a native speaker
  • 4For published content, always have a native speaker review — AI translation is a draft, not a finished product
