sui juris /suːiː ˈdʒʊərɪs/ adj. — of one's own right; legally independent.
Private AI today is a pile of parts and a weekend you don't have. Suijuris interviews your firm, assembles the entire stack — inference, knowledge, interface, security, audit — and hands you a working assistant on hardware you own. Nothing leaves the building.
Built for regulated firms — solicitors, accountants, clinics — and anyone whose data can't live in someone else's cloud.

The agentic provisioner
No Docker files. No GPU driver archaeology. The provisioner asks what you do, what you must comply with, and what you want the assistant to know — then assembles and configures every layer on your box.
The complete package
Same appliance, same sovereignty, same monthly care — sized to the firm. The provisioner recommends yours during the interview.
One person or household. Private chat and your personal documents, answered offline — homework help that never phones home.
The firm's knowledge base ingested; role-based access for the team; audit ledger on; privilege-safe defaults from day one.
Multi-team firms. Heavier retrieval, departmental workspaces, paired appliances working as one — still nothing leaving the building.
Why Suijuris
None of those keep client files in the building, survive their own updates, and hand you an audit trail a regulator can read.
