01 — Definitions

What “private AI” and “local AI server” actually mean

These two phrases get used loosely, so it’s worth being precise about them before anything else — because the distinction is the entire reason a business would choose this over the AI tools it already has.

Private AI

AI that runs on hardware you control

Private AI is an AI system that operates on equipment your business owns, rather than on servers belonging to an outside company. When someone on your team types a question, uploads a document, or asks for a draft, the request is answered entirely inside your own network. Nothing is transmitted to OpenAI, Google, Microsoft, or any other AI vendor — because there’s no vendor in the loop at all.

It exists as a direct answer to the question every business eventually asks about tools like ChatGPT: where does what we type actually go, and who else can see it? With a private system, the answer is simple, because there’s only one place it goes — your own box.

  • The model runs on a machine in your office, not a data center you’ve never seen.
  • Files, conversations, and generated answers are processed and stored on-site.
  • You decide who on your team has access, and to what.
Local AI Server

The machine that makes it real

A local AI server — also called on-premise or self-hosted AI — is the actual computer that sits on your network and does the thinking. It’s the physical (or virtual) engine underneath the phrase “private AI.” Instead of your questions travelling across the internet to a company’s data center and back, they’re handled start to finish by a processor sitting a few feet from your desk.

Early versions of this idea meant assembling a GPU rig and wrestling with command-line tools — genuinely a job for an engineer. A ready-made appliance changes that: it arrives configured, plugs into your existing office network, and your team logs in from an ordinary web browser, exactly like they would with any cloud tool.

  • Runs the AI model on its own processor and memory — no cloud dependency.
  • Keeps functioning through internet outages, price hikes, or a vendor shutting down.
  • Answers from your own uploaded documents, with the source cited.

“Private,” “local,” “on-premise,” and “self-hosted” are, in practice, four names for the same idea: the AI runs on hardware you control, inside your own walls, instead of inside somebody else’s cloud.

— the short answer, if you only remember one line

02 — Why it matters

Why businesses are moving work off the cloud

Cloud AI tools are genuinely useful, which is exactly the problem — teams start pasting in exactly the material that shouldn’t leave the building: contracts, patient notes, financial statements, unreleased pricing, client lists. A private, local AI server removes that trade-off instead of just managing it.

The confidentiality problem cloud AI can’t solve

Some information simply cannot be handed to an outside company, no matter how good its privacy policy reads. Attorney-client material, protected health information, unreleased financials, and proprietary client data all fall into this category for most regulated or client-facing businesses. Even “enterprise” tiers of the big cloud AI tools — the ones that promise not to train on your conversations — still route every message through a third party’s infrastructure, subject to that company’s outages, policy changes, breach history, and pricing decisions. A private AI server removes the third party from the equation entirely: there’s nothing to trust, because nothing leaves the building in the first place.

Ongoing cost, not just risk

The second driver is economics. Per-seat AI subscriptions add up quickly and never stop — ten employees at roughly $30 each per month is over $3,600 a year, forever, and the price is the vendor’s to raise whenever they choose. A local AI appliance is typically bought once, covers everyone in the office at no additional cost per login, and keeps running indefinitely, even without further payments.

Working without the internet

A private AI server keeps functioning if the office internet goes down, if a cloud vendor has an outage, or if a subscription policy changes overnight. The intelligence lives in the building, not in someone else’s uptime record.

03 — Mechanics

How a private office AI actually works

Nothing exotic is happening under the hood — it’s the same idea as any office server, applied to AI instead of email or file storage.

The appliance is a compact, quiet computer that plugs into your existing office network like a printer or a NAS. It comes with the AI models already installed. When you turn it on, it starts serving a private web app at an address on your own network — something like youroffice.local — and anyone on the office Wi-Fi can open it in an ordinary browser and log in with their own account.

From there, every request — a chat message, a document upload, a request for a draft proposal — is handled entirely by the box’s own processor and memory. The AI model itself is a file that lives on the machine: it was trained on an enormous amount of text before it ever arrived at your office, and that learning is compressed into the model, the way a well-read colleague carries knowledge around without needing to look everything up. General knowledge and reasoning are built in from day one; anything current or company-specific comes from what your team uploads, or from the optional web search add-on.

You choose how much “thinking power” to run via the AI engine tier — a lighter engine for everyday writing and summaries, and a stronger one for harder reasoning and reading scanned documents or screenshots. Switching is instant on the appliance, because every engine is preloaded.

Two things are worth being explicit about, because they’re the whole point: first, nothing about a normal day of use requires the internet — chat, document answers, scheduling, and document generation all run entirely on the local network. Second, the only things that ever reach outside your building are things you deliberately turn on: the optional web-lookup add-on (and even then, only the search words leave, never your files), the optional remote-access tunnel, and a small licence/update check that never carries any of your content.

Step 1

The box joins your network

Plug it into power and your router with the included cable. It’s discoverable at a friendly local address the moment it’s on.

Step 2

Your team logs in from a browser

Each person gets their own account and role. No installs, no IT ticket — it works like any web app already in the office.

Step 3

Everything runs on-site

Chat, document answers, scheduling and drafting are computed on the box itself — never uploaded anywhere else.


04 — What’s inside the box

One office AI, nine tools your team already needs

Every item below runs on the same box, under the same login system, sharing the same permissions — no extra software to buy, no data scattered across five different apps.

Private AI Chat

A ChatGPT-style assistant for every employee — drafting emails, summarizing documents, brainstorming, translating, writing and fixing code, or just thinking through a problem out loud. It feels exactly like the tools your team already knows, except it runs on your own hardware, keeps a searchable history, and nothing typed into it ever leaves the building.

Includes a deep-thinking mode for harder questions, file and screenshot attachments right in the conversation, and fully offline operation on the office Wi-Fi.

Company Knowledge Base

Drop your policies, contracts, handbooks and reference files into folders, and your AI answers questions straight from them instead of guessing. Ask “what’s our refund policy?” or “what did we quote this client?” and get a direct answer with the exact source file cited — no more digging through shared drives.

Handles PDF, Word, Excel, PowerPoint, plain text and CSV files up to 25 MB each, organized into role-based folders so HR material stays with HR.

Team Accounts & Permissions

Every employee gets a login — there are no per-seat fees, so add as many people as your office actually has. Build roles that match how you already work (Manager, Contributor, HR, Guest, or fully custom) and control exactly what each person can see and do, from which knowledge folders down to which calendars.

Disable an account instantly the moment someone leaves. Admins manage the whole team from a single page — no IT department required.

Team Chat Rooms

Spin up shared rooms for the whole office, a department, or a single project. Teammates chat in real time, ping each other with @name, and — the genuinely useful part — pull the AI directly into the conversation with @ai, where it can answer, draft, or look something up for the whole group without anyone leaving the room.

Rooms are scoped by role, so the right people are in the right conversations, and everything stays private to your team on your own box.

Document & Email Generator

Pick a template — a proposal, a price quote, a client follow-up — choose the client from your contacts, and the AI writes a polished, ready-to-send document filled in with your real business details and pricing. Preview it live, ask for changes in plain language (“make it shorter,” “add a payment schedule”), and export a branded PDF.

Comes with built-in templates or lets you build your own, so every document goes out sounding like your company, not a generic AI.

Contacts Directory

Keep your clients and business contacts in one place, on your own machine. Import an existing list from a CSV in one step, manage it in bulk, and export it any time — it’s your data, so it stays portable. The directory plugs straight into the rest of the box: pick a contact when generating a document or scheduling an event, and the details fill themselves in.

Ask your AI a quick question like “what’s their email?” and it answers straight from the directory.

Shared Calendar

A team calendar that lives on the box, with month and agenda views and per-event visibility — everyone, a specific role, or just you. Link events to a contact, and let your AI help out: ask “what’s on this week?” in chat, or say “add a call with Acme at 2pm” and confirm the event it drafts for you.

Private events stay private automatically — visibility follows the same roles you’ve already set up for the rest of the team.

Add-on · $19/mo

Web Access

The box is fully offline by default. Turn on Web Access and your AI can pull in current information — prices, news, addresses — the moment a question actually needs it, citing the site it came from. Only the search words involved ever leave your building; your documents, chats, and files never do, and the box never holds a search-engine key of its own.

Toggle it per question, or let the AI decide automatically when a lookup would help.

Add-on · $29/mo

Remote Access

The box lives on the office network, but work doesn’t always stay there. Remote Access opens a private, end-to-end encrypted tunnel so your team can reach the office AI securely from home or the road — without opening a single port on your router or exposing the box to the public internet. Only your own signed-in devices can ever reach it.

Turn it on or off any time from your account — there’s no minimum term, and the office network keeps working normally either way.


05 — Setup & support

Getting it running takes minutes, not an IT project

There are two ways to run Private Office AI, and everything below applies to both — the ready-made appliance, or software installed on a Mac or PC you already own.

The box

Plug in, log in

Connect the included power and network cable, then open a browser on any device on the same Wi-Fi and go to the address on the setup card — its friendly .local name or its network address. The AI engines and remote-access app are already installed; there’s nothing to download.

The software

Runs on your own machine

Download the installer from your account and run it — it checks your machine’s memory and sets itself up in a few minutes on Mac, Windows, or Linux. It needs an Apple Silicon Mac or a modern PC with at least 16 GB of memory; 32 GB or more unlocks the strongest AI engine, including reading scanned images.

First-time setup, in order

The first screen you see asks for a handful of things: a licence key (software only — the box already has one built in), your company name to brand the workspace, an optional custom web address like yourcompany.privateofficeai.com so nobody has to remember an IP address, and finally the owner’s name, email and password. The AI starts on its lightest engine so it’s usable immediately, and you can move up to a stronger one any time from Settings.

Choosing an AI engine

Think of the engine as how much thinking power you’re dialing in. Swift is quick and light, great for everyday writing and knowledge-base answers. Balanced adds stronger reasoning and is the right default for most offices. Maximum is the deepest reasoning tier, and the only one that reads images, screenshots and scanned documents. A box has every engine preloaded, so switching is instant and fully offline.

Adding your team

From the Team page, add a person by name and email — they receive a temporary password by email and choose their own on first login. You can promote someone to Administrator, reset a password, or disable access instantly if someone leaves. Two roles exist from day one — Administrator and Team member — and you can add ready-made roles like Manager, Contributor, Basic user, or Guest, or build fully custom ones by ticking exactly the permissions you want.

Backups, updates, and what happens if the power goes out

The box backs itself up roughly once a day and keeps the fourteen most recent snapshots, stored on the box itself — nothing goes to the cloud, so a mistake stays recoverable without adding a privacy risk. If the power cuts out or the box restarts, it starts your office AI back up automatically the moment it boots. Every purchase includes a full year of free software and security updates, installed automatically in the background without interrupting a live conversation; after that, an optional Care Plan keeps them coming, though the box keeps working forever either way.

If something goes wrong

Most one-off issues clear with a simple restart of the box. Can’t reach it on the network? Confirm your device is on the same Wi-Fi and try its local name or network address from Settings. An add-on you just paid for not showing as active yet? Give it a few minutes, or check for it manually from the Add-ons page. Only the Maximum engine reads images — if a screenshot isn’t being read, that’s usually why. For anything else, real people are available by email, and Care Plan customers get priority support with remote fixes.

What three years of AI actually costs

Compared using publicly advertised pricing as of July 2026: a typical per-seat AI subscription, a leased private-AI appliance, and a PrivateOffice Box paid once.

Team sizePer-seat subscription (~$30/user/mo)Leased appliance (from $300/user/mo)PrivateOffice Box
5 people$5,400$54,000$4,900
10 people$10,800$108,000$4,900
15 people$16,200$162,000$4,900

The box is paid once — subscriptions renew forever, at a price the vendor sets. Everyone in the office is included, so there’s no per-seat math or upgrade calls, and nothing about your data ever needs an asterisk.


07 — Who this is built for

Built for offices that can’t risk their data

Any business with confidential client material, competitive documents, or simply a team it wants to equip properly benefits from this — but a few industries feel it immediately.

Law Firms

Privileged material stays privileged

Confidentiality rules out feeding case material into a cloud AI. A private box lets attorneys and staff summarize filings, draft correspondence, and pull answers from matter files and precedent — with nothing ever leaving the office.

  • Answers from matter files, with sources
  • Role-based access for sensitive matters
  • Draft letters and memos in seconds
Accounting Firms

Every number stays on your box

Client financials are as sensitive as data gets. A private AI speeds up summarizing documents, drafting client letters, and explaining line items — while every figure stays on a machine your firm owns outright.

  • Summarize financial documents instantly
  • Draft engagement letters and client emails
  • Answer from your own procedures, with sources
Marketing & Creative Agencies

One shared AI for the whole studio

Agencies live on output. A shared box lets the whole team draft copy, brainstorm campaigns, and write proposals grounded in real client briefs and brand guidelines — instead of client work scattered across personal AI accounts.

  • Draft copy and campaign ideas fast
  • Grounded in your client docs and voice
  • Team rooms keep the whole studio in sync
Dental & Medical Offices

Patient information never leaves the practice

Health practices handle sensitive information that can’t go to a public AI. A private box gives the front desk and providers an assistant for patient communications, policy lookups, and billing letters — processed locally, on hardware you control.

  • Draft patient communications quickly
  • Answer staff questions from your protocols
  • Every login has the right permissions
Real Estate

Fast, sharp communication, without the leaks

Real estate runs on speed. Give agents an assistant that drafts listing copy and client emails, answers contract and disclosure questions from your own files, and keeps everyone’s knowledge in one place — in your office, not a vendor’s cloud.

  • Write listings and follow-ups in your voice
  • Answer questions from contracts and disclosures
  • Generate branded proposals in one click
Small Businesses

Enterprise-grade AI, no IT department needed

You don’t need an IT team or a stack of subscriptions to give your staff great AI. Plug in a box and everyone gets a shared assistant for email, documents, scheduling, and answers from your own files — bought once, owned forever.

  • One flat price, no per-seat fees
  • Handles the everyday: drafts, summaries, scheduling
  • Plug in, log in, done

08 — Frequently asked questions

Everything people ask before they buy

Straight answers about privacy, offline use, hardware, and what happens after the sale.

Does it really work with no internet?+
Yes. The AI model runs on the box’s own hardware, so chat, document answers, and everyday work all function fully offline on the office Wi-Fi. The only things that ever need the internet are the optional Web Access add-on and a small licence/update check — never your data.
Where does our data actually live?+
On your box, in your building. Every document, question, and answer is stored and processed on the machine itself, never sent to us or any cloud AI company. If every AI vendor on earth vanished tomorrow, your office AI would still work fine on Monday morning.
What information does the company actually receive from our box?+
Two small, optional signals: a licence/version check, and — only if you claim a custom web address — your box’s local network address. Never document contents, chats, file names, or anything your team types.
How does it know facts if it isn’t connected to the internet?+
The model studied a huge amount of text during training and carries that learning inside the file that runs on your box, much like a well-read colleague who doesn’t need to look everything up. For anything current or company-specific, add the Web Access add-on or upload your own files.
Can it answer questions from our own company documents?+
Yes — that’s the core of the Knowledge Base feature. Upload policies, contracts and files into role-based folders, and your team gets instant answers with the source cited, drawn from your own material rather than the open internet.
Is it aware of who’s on the team, and what they’re allowed to see?+
Fully. Every person gets their own login, and the roles you set govern folders, chats, calendars and rooms — so HR files stay with HR, and shared knowledge is scoped to exactly the right people.
Are software updates included, and for how long?+
Every box and licence includes one full year of free software and security updates from the date of purchase. After that, an optional Care Plan keeps updates coming — but the box keeps working forever either way, simply running the version it already has.
What hardware does the software edition need?+
An Apple Silicon Mac or a modern PC with at least 16 GB of memory runs the everyday engine well; 32 GB or more unlocks the strongest engines, including image reading. It installs in a few minutes and checks your machine automatically during setup.
How many people can actually use it?+
Everyone in your office — there are no per-seat fees at all. Add as many logins as your team needs at no extra cost.
What if it doesn’t work out, or something breaks?+
30-day returns from delivery for a full refund if it doesn’t perform as promised, plus a one-year hardware warranty on the appliance itself.
Which AI models does it actually run?+
Open-weight models, tuned and maintained under the hood, running locally through a standard local-AI engine. You choose a tier for how much answering power you want, and the system handles the rest.
Is a local AI server as capable as ChatGPT?+
For everyday office work — drafting, summarizing, answering from your own files — a modern local AI is very capable, and the strongest engine handles deep reasoning and reads images and scans. Cloud models can still edge ahead on the very hardest open-ended tasks, but for typical business use the gap is small, and the privacy gain is large.
