Pi is a kind voice. Luna is a kind voice plus a brain and a builder
Pi pioneered the friendly-AI voice and is great at empathetic listening. Luna takes that warmth and stacks on persistent cross-device memory, 92 agentic tools, an in-app code studio, and full sovereignty.
| Capability | LUNA | Pi (Inflection AI) |
|---|---|---|
| Voice quality | Chirp 3 HD, real-time | High |
| Memory across devices | Yes | Limited |
| Agentic tool use (web, code, vision) | 92+ | Conversation-only |
| Builds apps | Yes | No |
| Self-hosted / sovereign option | Yes | No |
| Available on macOS | Yes | Web/mobile |
Pi (Inflection AI) solves one piece of the problem well. Luna combines the companion dimension with the agentic and builder dimensions, on sovereign infrastructure. That combination is the category Heaven is building — and there is no second product in it yet.
