Which plan to pickStart on Free. If you translate documents or customer emails every week, Individual on a yearly plan is the sweet spot and stops DeepL keeping your text. Move to Team only when several people need the same glossary.Start on Free. If you check more than a few documents a week, Premium on yearly billing is the sweet spot. Professional only makes sense if you scan big batches of files.Use Basic for a week to see if you reach for it. If you do, Unlimited on yearly billing is the one to get, because Advanced still caps your rewrites. There are no refunds, so cancel during the 3-day trial if it isn't for you.

Pros and cons

AttributeDeepLGPTZeroWordtune
Pros
  • More natural translations than Google Translate in most European languages
  • Documents keep their formatting after translation
  • Glossaries keep your terms consistent
  • Paid plans don't store or train on your text

Cons
  • Free plan is small: 50,000 characters and one file a month
  • Weaker on Japanese, Chinese and Korean than a good chat assistant, and newer languages are uneven
  • Many complaints about renewal charges, refused refunds and slow support, so diarise the end of any trial
  • Long-time users report it got slower and less literal in 2026, sometimes rewording the meaning, so legal text still needs a human
  • Glossary and file limits are tight on the cheaper plans
  • False positives happen, and short or formal writing gets flagged more often
  • Edited or reworded AI text can get past it
  • The best scan and plagiarism checks need a paid plan
  • Mostly designed around schools, so some features won't matter to a business
  • Free plan stops at 10 rewrites a day
  • No refunds, only a 3-day trial
  • A chat assistant you already pay for can do the same
  • Its owner has moved its focus elsewhere, so new features are rare
