For law firms

Give AI the judgment context behind every matter.

Percidian gives every approved AI tool a deep, permissioned understanding of your clients, matters, documents, communications, precedents, deadlines, and decisions — resolved per lawyer before any context reaches an AI system, and remembered across matters, sessions, and models. Lawyers receive the context of the work, not another search box.

Two matters, one firm

What each lawyer receives — and what never crosses the wall.

Ethical walls, matter restrictions, and privilege are resolved before any context reaches an AI system. Privileged and matter-confidential material stays on its matter; the public record crosses; a screened person receives the public record and nothing else.

Who is asking

Litigation associate · Acme v. Northstar“What does the firm know about Northstar?”

Delivered to the AI · Litigation associate · Acme v. Northstar

Why this view? The whole matter, privileged work product included, plus the public record from the other side. Halcyon’s deal is behind the wall — not locked, absent.

Illustrative example

How it holds

Enforced on every request — not left to be remembered.

The wall is not a policy the AI is told about. It is applied to the context before generation begins.

  • Walls and screensWalled matters and screened individuals are excluded before context is assembled — absent, not shown behind a lock.Before generation
