Get a free DeepL API key

Step by step, sign up for DeepL API Free (500,000 characters a month) and paste the key into Plainstamp.

DeepL API Free translates up to 500,000 characters a month at no cost. Many people find its Spanish and Portuguese especially natural. It takes about 5 minutes.

DeepL can't translate into Haitian Creole, Vietnamese, Filipino, Hindi, Hebrew or Yiddish. If anyone on your team reads one of those, use Azure or Google instead.
