Butler processes your internal data without external AI models. It applies company policy first, logs each use as a fingerprint (digest), and learns only from policy-verified results. No data leaves your company — yet it grows into your own AI OS that can even propose your growth strategy.

What Makes Butler Different
Runs on employee devices and the internal network only. Works even when the internet is down.
Each team learns independently. Sales becomes a sales expert, accounting an accounting expert.
Instead of buying new servers, the PCs already in your company automatically join the compute cluster.
The Dilemma
The moment employees put work content into ChatGPT, Copilot, or Claude, contracts, financials, customer data, and internal strategy flow to external servers. The more employees use it, the greater the exposure.
Block AI to protect security? Employees go back to manual work, while competitors using AI pull further ahead every day.
AI runs entirely inside your organization. Everyone can use it freely, and the more they do, the better it knows your company.
Core Value — Sovereign AI OS
No matter how long or how much you use current AI — it still does not know your company. A year from now, it is the same AI.
Butler changes with use. Your team language, the way you work, the know-how built over years — it all seeps into the AI, until one day it becomes an AI that only your company knows.

3-Layer Architecture
From personal devices to team servers to the central server — all connected only within your internal network. A fully on-premise structure with no path to the outside internet. This is true enterprise data sovereignty.
Personal Device — On-Device Agent
Employee PCs · Laptops · Tablets
Team Server — Dedicated Team PC
Not a data center — a dedicated high-spec team PC
Central Server — Enterprise AI Gateway
Central hub for managing AI across the whole organization
외부 인터넷으로 나가는 경로는 처음부터 없습니다 — 외부 API가 필요할 때도 중앙 서버에서만 호출합니다.

Technical Differentiation
AI that becomes your company
Every use accumulates your company's data and trains the AI automatically. The company-specific AI built this way cannot be replicated anywhere else.
Device → Team Server → Central — all internal
All three layers connect only within your internal network. There is no path to the outside internet from the start.
Automatic model selection based on device state
Measures CPU, RAM, battery, and heat in real time to automatically choose between the high-performance (7B) and lightweight (1.5B) model.
Company policy before AI response
Department, role, and data-tier permissions are checked before any AI selection. Policy violations are blocked at the gateway immediately.
Fully owned, no subscription
No monthly fees, no external API dependency. The model, servers, and knowledge base are all owned and operated directly by your organization.
Technical Resources
Comprehensive technical resources organized into 16 sections. From system architecture to distributed computing, security, and deployment options.
