Simple by design

Three steps to clarity

No setup. No account. Just open the app, and let a calm, neutral voice guide you forward.

1

Start a Session

Open the app and choose your topic — a disagreement, a recurring pattern, a family decision. No accounts or sign-ins required.

2

Speak Freely

Both parties share their perspective. The AI listens attentively, never interrupts, never judges — and never sends a word to any server.

3

Reach Resolution

The AI synthesises both perspectives into a structured, actionable path forward — so you leave the room with clarity, not just catharsis.

Everything runs locally on your device

The AI model is downloaded once and runs entirely offline. Your conversations are processed in-memory and never written to disk or transmitted anywhere.

Our core promise

Your conversations stay yours.

In an era of AI that feeds on your data, we made the opposite choice. Every word you speak stays on your device, period.

We don't need your data to help you. We just need to be in the room.
