I can also recommend it. It beats most of the existing translation services and we're happy with it at STOMT
I don't see pricing or an API from DeepL that could be classified as a 'service'. Am I missing it?
No monetization from the team on this particular product (yet). But, there are unofficial API frameworks (Search NPM for example) & they haven't really implemented any aggressive rate-limiting. Normal usage should be fine.
Just played with this for my app's description and it's pretty amazing. Definitely recommend.
