Value proposition

Local-first, privacy-preserving AI assistant (Naia OS) that runs entirely on the user's computer — no cloud dependency, no data leakage. Open source (Apache 2.0), free to use, with 5,700+ skills and memory that persists across sessions.

Products and solutions

Naia OS (personal on-device AI assistant with BGM player, memory, skills, and agent capabilities); Naia AX (enterprise AI transformation — infrastructure migration, AI service development, revenue share model); AieDu (AI education platform with 23 pedagogies, in-browser coding, custom curricula); Business ADK (AI Development Kit for enterprise deployment); Starnion (AI web service builder)

Unique value

The only on-device AI OS that combines a BGM player interface with a full AI agent system, featuring neuroscience-based multi-store memory (episodic/semantic/procedural), runs locally without internet, and is fully open source under Apache 2.0 — giving users true AI sovereignty over their data.

Target customer

B2C: Privacy-conscious individual users in South Korea who want a local AI assistant; B2B: Enterprises needing AI transformation (AX) with on-premise/air-gapped deployment; B2B2C: Educational institutions needing AI-powered curriculum delivery

Industries served

Personal AI assistants; Enterprise AI transformation; AI education; Religious organizations (church platform modernization)

Technology advantage

8 patent applications filed covering: multi-store memory management for AI agents, multi-agent cross-verification framework, AI curriculum auto-generation, codebase-driven patent discovery pipeline, legacy website migration automation, multi-tenant SaaS AI agent harness, dynamic panel extension, and real-time memory context compaction. All core technology is open source (Apache 2.0).

How they differentiate

1) Fully local/on-device — no cloud dependency, data never leaves user's computer; 2) Open source (Apache 2.0) with complete code transparency; 3) Neuroscience-based 4-tier memory architecture (episodic, semantic, procedural, working); 4) Built using AI itself (Naia is developed with Naia); 5) BGM player as entry point — lowers barrier to adoption; 6) 8 patents filed covering core technologies; 7) Korean language-optimized with Korean voice model research
