I loosely used the term 'AI'. Most people don't exactly know what artificial intelligence is or how it works, so using the terms according to their definitions sometimes creates more confusion than clarity.

Of course translation tools like DeepL have always been based on machine learning. The difference is that a few years ago DeepL worked well and its home page wasn't filled with 'AI this' and 'AI that'. They seem to have transitioned from their old ML models to some of the newer LLMs. From my experience the translation quality is much worse than it used to be.
