Just put megalodon.jp before the site you want to archive, then click the smaller of the two buttons in the center to archive.

On Brave, there's a built-in translator and I assume this is a feature in other browsers, so you can use that as well.

I haven't used it on paywalled sites yet, so that could still be a reason to use archive.today. But it archives Reddit fine.

If you're seriously archiving, you should use as many different sites as you can, but for me, I'll use megalodon when I want to archive.
