I'm interested but when I provided my email address to get notifications, I am prompted to either sign in to or create an account at something called MailerLite. No idea what that's about, not gonna do it. You gotta realize that at this late date, my threshold for creating new accounts is pretty high. If I don't know exactly what I'm signing up for and why, I'm not gonna do it.

Looks very promising especially the math friendly interface and the local-first capability with great name to boot.

Just wondering does Noteworthy uses blocks concept similar to Notion [1]?
