An AI app you actually use every day, Naia
Starts as a BGM player with a character. It remembers, talks, and does what you tell it. The founder plays BGM on it while building it.
Current Traction
The code speaks for itself
Start light. Go deep.
Install it as a BGM player. Use it more and it becomes an AI agent. The same architecture powers enterprise deployments.

What's underneath
What makes a usable app keep getting better
Built with itself
Naia is developed using Naia. AI writes the code, humans set the direction. This is how Phase 0-7 got done in 30 days.
GitHub →Memory that sticks
Remembers naturally through conversation. Gets to know you more over time. Three-layer storage: episodic, semantic, procedural. Patent filed.
GitHub →Local AI
Runs without internet. Korean voice model research in progress. Your computer becomes the AI server.
GitHub →Business Model

How we build
AI Native Open Source
AI Slop isn't just bad code — it's contributing without understanding the project or its community. Nextain builds a structure where AI understands project context and passes adversarial review from an upstream maintainer's perspective — creating an open source ecosystem grown together with AI.
Local-First, Private by Design
Memory, personality, and conversations stay on your device. No data leaves unless you choose otherwise. Your data, your decision.
Solid AI Infrastructure
In the enterprise, AI running without understanding the business context is the same AI Slop problem. Nextain builds infrastructure for AI agents that understand your systems and operate safely within them.

Partners
With your own AI
"In an era where we must live alongside AI, we inevitably share more and more with it. Yet the reality of entrusting a cloud AI — opaque and subject to change at any moment — as our partner leaves an unavoidable sense of unease. Nextain builds on transparent open source to create a trustworthy AI that exists only on your computer, shares memories with you, and grows alongside you — the one and only AI that is truly yours."
