Google Translate supports well over 100 languages and works across web, mobile, camera and conversation modes. It is free for everyday use and integrates with Chrome and Android.

Pros

  • Very broad language coverage
  • Free, fast and available everywhere

Cons

  • Less polished tone on nuanced text
  • Free consumer use is not suited to confidential material

Pros

  • Follows detailed style and formatting instructions
  • Can explain translation choices

Cons

  • Can add or omit content if not instructed carefully
  • Consistency across long documents requires prompting

Engineering teams embedding translation into apps. Individuals should choose another option.
