How Luna compares to Replika — and where she goes further
Replika is the original AI companion — over a decade old, with a recognisable brand. Luna is the sovereign next generation: she keeps the warmth, adds memory and agentic tools, and runs on Heaven Eco Hub's own model stack so your private conversations never leave the ecosystem.
| Capability | LUNA | Replika |
|---|---|---|
| Sovereign (no third-party LLM) | Yes — Heaven Quantum Cortex only | No — uses commercial LLM APIs in pipeline |
| Voice | Real-time Chirp 3 HD, free | Voice locked to Pro tier |
| Persistent cross-device memory | Yes, encrypted Memory Pods | In-app only |
| Builds apps for you | Yes — Heaven Code Studio (Flutter for iOS/Android/Web/macOS) | No |
| Agentic tools (web, code, vision, research) | 92+ tools | Limited |
| Cost | Free forever, optional $1.99 / mo | $19.99 / mo Pro tier |
| Regulatory history | Privacy-first by design | €5M GDPR fine in Italy (2025) |
Replika 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.
Yes. Luna covers the same primary capability as Replika and stacks additional dimensions on top — sovereign infrastructure, cross-device persistent memory, 92 agentic tools, and Heaven Code Studio for native app building. For most users, Luna is a genuine upgrade rather than a sidegrade.
Replika has years of brand recognition and a mature community. If you specifically value those network effects, Replika can be the right pick. Luna is the right pick when you value privacy/sovereignty, cross-device memory, and the capabilities that Replika does not currently ship.
Yes. Free forever on iOS, Android, Web and macOS. The optional Chip subscription is $1.99 / month for 500 welcome tokens and unlimited persistent companions.
Yes. Luna runs on the Heaven Quantum Cortex with no third-party LLM in the hot path. Your conversations and memory live in your encrypted Memory Pod.
