Last Word

// Demo

// The build

No accounts is the whole product. Last Word is a note that exists exactly once: write it, share a link, and the first person to open it deletes it in the same instant, mid-request, atomically. Twenty simultaneous readers, one winner. AES-GCM in your browser; the key lives only in the link fragment, which never reaches a server. No sign-up, no email, no logs, no analytics. The server holds ciphertext and a timestamp, nothing else. Even we couldn’t have read it. Built solo in the 48 hours.
