subtext. Private messaging

End-to-end encrypted ยท Built for iPhone

A message that looks like nothing.

Subtext hides an encrypted note inside a single emoji. Paste it into any chat and it looks like an ordinary . Only the person you sent it to โ€” with Face ID โ€” can read what's underneath.

See what's underneath

To anyone glancing over a shoulder, this bubble is one emoji. Tap to decrypt it the way the app does โ€” behind your face.

Your name is one emoji

Claim your handle before someone else does.

Every handle resolves to your encryption key, so friends just type your emoji and the message seals itself. Three-emoji names are free and endless. Two are scarce. A single emoji is one of a kind โ€” and once it's taken, it's gone.

Why it holds up

Real cryptography, dressed as an emoji.

Hidden in plain sight

The ciphertext rides as invisible characters on one carrier emoji. It travels through iMessage, notes, anywhere text goes โ€” looking like nothing.

Sealed to one person

Public-key encryption on Apple's own CryptoKit. Only your recipient's key opens it โ€” not us, not the network, not a bystander.

Face ID to read

The decryption key lives behind the Secure Enclave. Reading a message isn't a screen you dismiss โ€” it's a lock that only your face opens.
