Which is the best AI for translating text?
For professional translation in 2026, Claude Sonnet 4.5 and GPT-4o dominate European language pairs: they preserve tone, intent, idioms and register better than DeepL or Google Translate. For technical translation (manuals, contracts), Claude is generally preferred for its precision on specialized vocabulary.

For Asian or rarer languages, Gemini 2.5 Pro has a slight edge due to its broader multilingual training. For massive volumes at low cost, DeepSeek V3 does a decent job 10× cheaper. The benefit of using a general-purpose AI over DeepL: you can specify context ("French legal text for a Belgian audience", "casual tone for a tech blog"), request alternative phrasings, or justify translation choices. On Ask Aurel, Compare mode lets you send the same sentence to 3 AIs and pick the best translation.
