Character variety, or a single companion who actually knows you
Character.AI wins for fictional character roleplay — 20M+ community characters. Luna wins for the relationship dimension: she is one consistent companion who remembers your real life and can also build apps, run agents, and hold a real voice conversation.
| Capability | LUNA | Character.AI |
|---|---|---|
| Character library | You can create personas, but Luna is primarily one companion | 20M+ community-built characters |
| Persistent memory across sessions | Yes | Limited / inconsistent |
| Real-time voice | Yes (Chirp 3 HD) | Limited |
| Builds working apps | Yes — Heaven Code Studio | No |
| Agentic tools | 92+ tools | No |
| Privacy | Sovereign — no third-party LLM in hot path | Runs on commercial LLM infra |
| Cost | Free forever | Free tier + paid |
Character.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.

Character.AI has years of brand recognition and a mature community. If you specifically value those network effects, Character.AI can be the right pick. Luna is the right pick when you value privacy/sovereignty, cross-device memory, and the capabilities that Character.AI does not currently ship.
