Honestly, a pretty neat tool. It's a bit buggy though, and I had to keep translate on through google chrome to use it, as it appears the whole thing is in Korean (despite the landing page being in english)

If you can get around those issues, it's solid.

You get a simple link, and paste it into Notion as an embed, and now you have free, anonymous comments on your Notion board!

If you're hosting a little Notion blog, it could be a neat addition. Users don't need to sign up, they just comment.

And you see every comment on a dashboard, but it doesn't seem to allow you to reply from the dashboard, and the subscribe feature also doesn't appear to work.

But, if the developer keeps improving the site, and it's been a while since this review was uploaded, I'd definitely give it a try.
