The nTier Platform
One Workspace. Three Places Your Data Can Go - And You Always Know Which One It Used.
Every AI request in nTier passes through a routing decision before it touches a model. Here's exactly how.

AI request
Review this matter
AI Residency
Local. Private. Public. You Never Choose - But You Always See.
Local AI
Runs entirely on your firm's own on-premise hardware. Used automatically for privileged and highly sensitive matter content, which never leaves your network.
Private AI
Runs in an isolated, firm-specific cloud environment. Used for client-confidential material that isn't privileged.
Public AI
Frontier AI models and your subscribed LegalTech platforms. Used only once content is confirmed non-confidential.
Every screen that uses AI shows a residency badge - so “where did this run” is never a question you have to ask support.

How a request is routed
What Happens Between Your Question and Your Answer
- 1
Your request is checked for privilege, confidentiality, and sensitive data - before any AI model sees it.
- 2
Based on that check and your firm's own policy, nTier picks the safest environment capable of doing the job.
- 3
If the task is complex, nTier may use more than one AI step to get it right - research, then drafting, then a final check.
- 4
If the result is high-stakes, it's held for a person to approve before it goes anywhere.
- 5
Your answer arrives with its source, its confidence, and where it ran, attached.
