Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on deepL Write for grammar and style suggestions, and strong privacy options on paid plans caught me off guard. still, I'd recommend giving it a real trial.

Does the job

Pretty happy overall. Browser extensions and desktop apps just works and available via web, desktop, mobile, and API. but no dealbreakers — I'd recommend it to a friend without hesitating.

Use it every day

Honestly didn't expect to like it this much. Neural machine translation for 30+ languages is exactly what I needed, and translations often sound more natural than competitors. I do wish supports fewer languages than Google Translate, but I reach for it almost every day now and it just clicks.
