Words stay words.
No photos. No videos. No attachments. No emoji, hidden characters, or rich formatting. Links stay plain text.
A deliberately small messaging service
Just text.
End to end.
You have something to say.
Send it. Encrypted. Leave the extras behind.
Coming sooniPhone + command line
The whole idea
95 characters.
Zero extras.
Letters, numbers, punctuation, and spaces. The 95 printable ASCII characters are the entire vocabulary.
For your contact.
Messages are encrypted on your device using Signal’s official libsignal. The relay delivers ciphertext; it does not hold the keys to read your text.
Checked on arrival.
The receiving app validates decrypted bytes before displaying anything. Non-ASCII and non-printable content is rejected, with an alert.
A first look
Less on screen.
More to say.
Actual screenshots from the iOS development build, using local demo accounts. Tap a screenshot to see it full size.
A Gmail address is enough to start.
Add the person you want to talk to, then verify their identity before exchanging messages.
Know who is on the other end.
Compare fingerprints through a separate, trusted channel. Verify the person before you send your words.
Small by design
A conversation.
Nothing attached.
ISYEET has one job: move encrypted text between people. That is the product, and the limit.
- A familiar address.
- Sign in with Google and add contacts by their Gmail address. Compare identity fingerprints through a separate, trusted channel before messaging.
- The same size on the wire.
- Messages of up to 1,024 characters are padded into fixed-size envelopes. Padding hides text length within that limit; it does not hide who communicates, when, or how often.
- A smaller surface.
- No media decoders, link previews, or message formatting engine. Fewer things to parse, and fewer ways for a message to pretend to be something else.
One job. On its way.
ISYEET is in development for iPhone and the command line. Public downloads are not available yet. Independent security review is still ahead.
