On-premise AI · In-house AI assistant · In production

Company files stay on the NAS,
AI does the answering.

Most small offices have no server, but they do have a NAS. A single container on the NAS your company already uses becomes an in-house AI assistant. Conversations, document indexes and surveys stay on company equipment; the only thing that leaves is the query text needed to generate an answer.

Three mismatches in today's design office

A closer look at the "resources · cost · security" story the video passes through quickly. As automation and AI arrive, the office balance is slipping in three places.

01 · Resources

PCs sit idle, servers run short

With automation reaching drafting work, fewer people do the same job. As headcount shrinks, the high-end PCs assigned per employee sit idle, while more servers are needed to run the automation. Yet most offices have no dedicated server — what they have is one NAS holding the files.

NAS AI's answerNo new server — one container on the NAS you already have. The NAS stays light, handling only storage, messenger and bot, and distributed processing that turns idle PCs into workers is in preparation.
02 · Cost

AI subscriptions pile onto licenses

The licenses you already pay for CAD and other software stay the same, and automation adds AI subscriptions on top. Subscribe per employee and the cost grows with headcount, while the company can hardly tell who uses what.

NAS AI's answerThe company bot (messenger · web chat) becomes the one approved AI channel. One company account, usage logged per employee, and AI usage fees included in the monthly upkeep.
03 · Security

Data leaks through everyone's own AI

When each employee uses AI through a personal account, drawing contents, client information and estimates can leave the company without anyone knowing. Ban it, and people use it secretly — a ban creates blind spots, not control.

NAS AI's answerDocuments, conversations and indexes stay on the company NAS; only the query text needed for an answer goes to the AI. Instead of a ban, a more convenient channel the company manages.

The three are not separate. Using the NAS you already have eases the server worry, and running AI through one company channel settles cost and security at once. That is why they are bundled into one solution.

One container, data stays in-house

Staff touchpoints
  • In-house messenger bot (Synology Chat)
  • In-house web chat — PC and phone, Google/Naver sign-in (listed emails only)
  • Voice input · executive voice assistant (optional)
Company network · company NAS — 1 container
  • Bot service (FastAPI) · intent router
  • File index — hundreds of thousands of documents, refreshed automatically every week at night
  • Project index · internal contacts · staff directory
  • Conversation log · weekly survey responses
  • Industry app bundle (cadastral DXF · site conditions · ground survey · road view)
AI model API Query text only · TLS
  • Only for generating text, understanding queries and classifying intent
  • No model training · limited retention
  • Original files never sent — file names and locations only
  • Swap the model with one line of config
StaffWhere are last year's structural drawings for the ○○ site?
NAS AI37 DWG files in the '○○ New Construction (2025)' structural folder — latest is S-201 foundation plan (Oct 14). Open it, or narrow it down?
Staffthe ground survey data too

Sample conversation — project names and figures are examples

When staff ask the bot

File search

Ask about hundreds of thousands of working documents in plain language and narrow down in conversation.

Project files

Points to file locations and status based on the project index.

Internal contacts

Finds extensions, emails and server accounts. Sensitive data is excluded.

NAS how-to

Sign-in, file recovery, sync — answers by searching the manufacturer's documentation.

Weekly work survey

The bot reaches out first, collects responses and tallies them automatically.

Voice assistant

Voice calls and web voice for executives, linked to calendar and contacts (optional).

A 4-app feasibility set — architecture, development, construction

DXF

Cadastral DXF

Address → cadastral DXF + site area + land schedule + preview. Pick the layers to include: zoning, roads, buildings and more.

Try it online ↗

The public demo contains only the cadastral map and parcel data. The in-house edition adds layer selection, the land schedule and chatbot integration.

LAND

Site conditions

Land category, official land price history, zoning, land-use regulations and the building register, organized in Excel.

BORE

Nearby ground survey

Shows nationally registered boreholes within a radius and their measured strata. No estimation, and it works without internet.

VIEW

Site road view

Address → road view from the nearest capture point. One line to the chatbot — "road view ○○" — is all it takes.

Designed so nothing leaves
company equipment

Conversations, surveys and indexes are stored only on the company NAS. Only the query text needed for an answer is sent to the AI model, encrypted, and it handles file names and locations instead of file contents.

  • Everything stored on the company NAS — conversations, surveys and indexes stay on company equipment
  • No model training — only the query text is sent, over TLS
  • Originals never sent — file names and locations, not file contents
  • Sensitive data excluded — passwords, HR and finance are outside the bot's knowledge
  • Home folders are private — excluded from general search
