Our verdict
DeepL produces the most natural-sounding machine translations available, consistently outperforming Google Translate in blind tests for European and major Asian languages. Its Write feature also helps improve writing quality in any language. Best for professionals, translators, and businesses. The main caveat is fewer languages than Google Translate and premium pricing for full API access.
