You can translate webpages already, like https://translate.kagi.com/English/Spanish/https://blog.kagi...

And with a bookmarklet you can trigger that with a click in your browser: https://help.kagi.com/kagi/translate/#browser-bookmarklet

This is probably like a browser extension and 45 minutes of vibe coding. I threw together a minimal MetaMask clone in a day, a simple page translator can’t even be a fraction of that. I actually love this idea so I might do it myself.
