FOUNDER’S EDITION · PROTOTYPE PROGRAM
LOCAL INTELLIGENCE.
NOTHING LEFT BEHIND.
One device. Two ways to listen. A private voice AI Core with a tiny detachable Pebble that goes where your phone should not have to.

THE DESIGN DECISION
A recorder should disappear.
The intelligence should stay with you.
Signal splits voice capture from voice compute. Clip the Pebble where it hears naturally. Keep the Core in your pocket, on the desk, or docked nearby.
TWO-PART HARDWARE
The phone is a compromise.
Signal is not.
Current AI recorders usually choose between tiny capture hardware that needs a cloud, or larger hardware that is awkward to wear. Signal separates the constraints.
Wear the microphone.
Keep the intelligence
in your hand.
- local speech processing
- encrypted memory store
- speaker + tactile controls
- optional LAN / cloud bridges
LOCAL BY DEFAULT
Your microphone should not require a server.
Capture stays yours.
Audio is designed to land in encrypted storage under per-device keys, not a vendor’s default cloud bucket.
Speech runs at the edge.
Whisper-class STT and Piper-class TTS are mature enough to form the local voice layer on compact ARM hardware.
Cloud is a connector.
Larger models or external services remain explicit and optional—not an invisible prerequisite.
SYSTEM ARCHITECTURE
Simple enough to trust.
Open enough to extend.
The launch architecture is deliberately composed from proven primitives rather than requiring a breakthrough chip, battery or model.
