First of all, you will probably tell me that the best thing to do is to learn this language, well yes, obviously, the bad thing is that I am very lazy for this, I can only learn a few things in English and then I get overwhelmed haha.
That said, before I never used a translator as I was always in Spanish communities, until I started to diversify more and now I need one, I am currently using DeepL as it has been useful for jargons that I don’t know, for more privacy I use it through an API key to use it in Translate You, but I heard that their privacy policy is a bit murky…
I’ve also heard of Simplytranslate but I think it uses Google’s servers in the same way…
Last I checked the highest quality widely used translator was deepl.com which is a commercial service that lets you translate only small snippets for free. To do larger ones you can upload them as pdf’s, which increases the size limits.
I’ve been using the local translator built into Firefox and it’s better than nothing, but it’s pretty rough compared to either google or DeepL.
I don’t think Kagi has its own translation service. They resell someone else’s.
