In fact many translation platforms do that automatically as suggestions.
Can I infodump how Pontoon handles it?
@GeopJr so Pontoon does indeed shows AI suggestions to translators, and by clicking on them they get copied to text area for translator to edit or click straight "submit". Its done using Google Cloud API and they cannot be disabled. However, in the hamburger menu there is an option to make the AI suggested text more informal/formal, and that is done using OpenAI API and Mozilla is paying for its usage.
There are also pre-translations, which are done using custom language models trained on language team's approved strings (i.e. strings that were pushed to the main), however it's opt-in for locale teams, and my team wasnt using them.
Personally, i only ended up using AI suggestions either same way as I would Google translate (i.e. when im stuck), or as a way to save up on typing (i have weak finger joints). I never used the "make more informal/formal" option.
