We build a sovereign AI companion — and we publish honest, in-depth guides about AI companions, agentic tools and privacy, so people can make good decisions.
LUNA is built by Heaven Eco Hub. LUNA is a sovereign AI companion and agentic AI app builder that talks, remembers across your devices, and builds real cross-platform apps from a single prompt — powered by our own reasoning engine, the Heaven Quantum Cortex, with no third-party language-model dependency. LUNA is free on iOS, Android, Web and macOS.
This site is our content library. Alongside the LUNA app, we write two kinds of articles:
We try to be useful before we are promotional. Every guide is written to stand on its own as a genuinely helpful read — with honest trade-offs, real comparisons and clear recommendations — whether or not you ever open LUNA. Where we recommend LUNA, we explain exactly why, and where another product is the better fit we say so.
Most AI companions route your private conversations through commercial language-model APIs. LUNA does not: the Heaven Quantum Cortex runs LUNA's reasoning natively, your memories live in an end-to-end encrypted Memory Pod, and your data is never piped to a third-party model unless you explicitly opt in. We write about privacy because we built the product around it.
