The same fate hit deepl. What most english users don't know is that translation from english to another language was always at best - horrible and not usable without much manual effort. The same goes the other way around when you are writing technical documents.

Deepl however - 7-8 or more years ago was bright star - i do not say this lightly but their translation (i can only vouch for german<->english) was out of this world in comparison to everything else like google translate, yahoo or whatever.

It was basically so good - i just kept writing in english even though its not my first language but its easier for technical documentation and i use it to translate back to german instead of doing it the other way around.

But then, when the first mass hysteria of chatgpt 1 etc hits - it good worse fast - nowadays - it can not do any good translation service at all - it is far worse than what the competition offered 7-8 years ago! It makes no sense a lot of times.
