About
Private AI for firms whose clients trust them with sensitive information.
One Premise is a UK company that installs, runs and supports private AI on a machine in your office.
Why we exist
AI is too useful to ban, and client data is too important to give away.
Professional firms are being asked to choose. Use public AI tools and accept that client documents will be processed on someone else's servers, or ban them and watch the work take longer than it needs to.
We think there's a better answer. The AI that helps your team summarise, draft and search can run on a small machine in your own office, where your client data already lives.
We set it up, connect it to your files, train your team and keep it running, for one fixed monthly price. You get the benefits of AI, and you can tell your clients exactly where their information is.
How we work
Four promises we don't bend.
- 01
Your data, your building
If a package can't keep your data on your premises, we won't call it One Premise.
- 02
Plain English
No jargon, no hype. We explain what it does, what it doesn't, and what it costs.
- 03
Nothing invented
No made-up testimonials, logos or badges. When we have proof, we'll show it.
- 04
We work with your IT provider
They keep your network. We bring the AI. Everyone knows who does what.
