A practical buyer's guide to picking a private AI for your office — team size, hardware, data sensitivity, features, and budget, with a decision checklist.
To choose a private AI for your office, match five things to your situation: team size, the hardware you already have, how sensitive your data is, the features you actually need, and your budget. Non-technical teams that want it done for them should pick a turnkey appliance like the PrivateOfficeAI Box; technical solo users can self-host on their own machine.
Choosing a private AI isn't about finding the "smartest" model — it's about matching a tool to how your office actually works. Walk through these five factors and the right answer usually becomes obvious.
A solo user or a two-person shop can run a private AI on a single computer. A growing office needs shared logins, permissions, and enough memory for several people at once. If more than a couple of people will use it, favor something built to be shared. The PrivateOffice Box suits teams up to about 15; the Pro handles larger, busier teams and bigger archives.
If you own a capable recent Mac or PC — ideally 16GB of memory or more — the $899 software edition can turn it into a private AI server today. 16GB runs the fast engine well; 32GB or more unlocks bigger engines. If you'd rather not tie up an existing machine or worry about specs, a ready-made box arrives sized and set up.
This is the factor that rules out cloud tools. If you handle client, patient, financial, or otherwise confidential material, it can't go to an outside service — which points squarely at on-premise AI, where nothing leaves the building. If your work is genuinely low-stakes, you have more freedom. Read how on-premise privacy works to understand exactly what does and doesn't leave your box.
List the jobs you want the AI to do, then check the tool has them built in:
A DIY setup gives you the chat but leaves the rest for you to build. An appliance includes all of it.
Match the engine to the work and the memory:
| Swift | Balanced | Maximum | |
|---|---|---|---|
| Best for | Fast everyday text | Stronger reasoning | Deepest reasoning + reads images/scans |
| Memory | 8GB+ | 16GB+ | 24GB+ (32GB recommended) |
Compare one-time versus recurring, not just today's price. A local box is bought once with no per-seat fees; cloud tools bill every person every month. Over a few years a one-time purchase usually costs less for a team. See the full breakdown in how much a local AI server costs.
Work through those seven steps and you'll have a confident answer. When you're ready, compare editions on the pricing page or read the FAQ for anything still open.
Choose the $899 software if you have a capable Mac or PC (16GB or more) and are comfortable installing it, especially for a solo user or tiny team. Choose the box if you want it ready to go, sized for a team, with engines and remote access pre-installed and no machine of your own tied up.
Match memory to people and tasks. A solo user is fine on modest hardware; a team of up to about 15 fits the PrivateOffice Box; larger or document-heavy teams want the Pro. Reading images and scans needs the Maximum engine with 24GB or more (32GB recommended).
If your work is genuinely low-stakes, a cloud tool can be fine. But a private AI still gives you no per-seat fees, offline reliability, and a shared team workspace — benefits that apply even when privacy is not the main driver.
Look for private chat, a knowledge base that answers from your own files, a document generator, and team accounts with role-based permissions. A turnkey appliance includes these; a DIY setup usually gives you only the chat and leaves the rest to build.
Yes. You can run a live demo to see the chat, knowledge base, and document tools in action, and PrivateOfficeAI includes a 30-day return window and a one-year hardware warranty so you can evaluate it in your own office with confidence.
