No-account mailing for $1.60 beats Lob's enterprise complexity for individuals.

Intriguing concept, but README is philosophy + vaporware with no working demo or code.
The interface sells the idea: a tiny form, character counter and a focused CTA that produces a unique share link — all wrapped in intentionally romantic typography and soft visuals. It's a nice micro-utility with clear intent, but it's not a new category (ephemeral/shareable notes already exist) and the site leaves questions about link expiry, privacy, and storage that would move it from cute toy to must-use tool.
