The Third Chair is a privacy-first AI mediator for couples, families, and households. It listens without judgment, guides without bias, and keeps every word on your device — because some conversations are too important to share with the cloud.
One-time payment · No subscription · No data harvesting
Simple by design
No setup. No account. Just open the app, and let a calm, neutral voice guide you forward.
Open the app and choose your topic — a disagreement, a recurring pattern, a family decision. No accounts or sign-ins required.
Both parties share their perspective. The AI listens attentively, never interrupts, never judges — and never sends a word to any server.
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
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.
