Heart Note – a tiny web app to send beautiful one‑off digital letters

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.
