A private AI you can point to.

AdminOnsite puts a small computer in your office that runs AI models on site. It drafts letters and replies, answers questions from your own files and keeps follow-ups moving, for one flat monthly price for the whole office.

Who runs it

AdminOnsite was founded in 2026 by Chris Tabb, who leads the company and is the author of the guides on this site. You can reach him at hello@adminonsite.com.

Why it exists

Before building anything, we read thousands of public posts from small-business owners, lawyers, accountants and insurance agents about the office work they want help with. Two things came up again and again in firms that handle client files: drafting takes a lot of time, and people don’t want to paste confidential files into a cloud chatbot. Per-seat AI subscriptions also add up fast for a whole team. AdminOnsite is our answer: the AI runs on hardware in your office, and everyone can use it for one price.

How we work

• Drafts wait for you. Nothing goes to a client until a person approves it.
• Open source. The software is a fork of Smart Node under the GNU AGPL-3.0. See Source.
• Honest about limits. Local models are very good at drafting, summaries and search, but they aren’t the strongest at open-ended reasoning. Our comparison says where cloud tools win.
• No compliance promises. We explain how the box handles data. Whether that meets your professional obligations is a decision for you and your advisors.
