It seems pretty crazy to handicap yourself with an unsearchable name like "Script", especially when it's not an editor for scripts (drama or programming).

The site has no scrollbar for some reason, so it's hard to navigate.

The HN title talks about interconnected documents, as if it's a wiki or something, but the site doesn't seem to mention that.

We've been working with truly digital documents for decades now, and it's not clear that this adds anything important. It also seems focused on proprietary lock-in, and doesn't have pricing available.
