SIPHER: Invisible Messages

Sipher is a privacy app built for real life—when you need to keep something discreet, but still look natural on your phone.

Create a cover conversation: a chat that appears completely normal on the surface, while protecting what you actually want to keep private. Choose a credible topic, generate a clean and realistic thread, and maintain a natural look if someone happens to glance at your screen.

Simple, fast, and designed for mobile, Sipher turns privacy into a discreet, intelligent experience you can actually use every day.

HOW IT WORKS

1. Set up your cover
Pick who the conversation is for and what it should look like on the surface—plans, work talk, gossip, movies, food, and more.

2. Generate a believable chat
Sipher creates a realistic conversation that feels natural, so your screen never looks suspicious.

3. Stay discreet in the moment
Your cover conversation helps you keep things private when someone is nearby or looking over your shoulder.

4. Use it from your keyboard
Send and manage protected messages directly from the Sipher keyboard in your favorite messaging apps.
