THORIS

by Mirasys

Everything examined. Nothing exposed.

Private AI case analysis. Air-gapped. Zero hallucinations. Built for law firms who cannot afford an incomplete picture.

The Problem

Three risks that keep partners up at night

01

Confidentiality Risk

Client data cannot leave the firm. Cloud AI and third-party systems create unacceptable exposure for sensitive matters.

02

Hallucination Risk

Generic AI invents facts, misstates sources, and produces plausible-sounding errors. In law, this is not a technical issue. It is a malpractice risk.

03

Wasted Institutional Knowledge

Decades of briefs, contracts, filings, and work product sit in files but cannot be reused. Firms constantly recreate work they already own.

The Solution

Every other platform is working with part of your case.

Public filings. Sanitized records. General models trained on data that isn't yours. Every legal AI platform on the market today builds its analysis on an incomplete picture.

Thoris examines your complete case record — every privileged document, every confidential filing, every internal communication — inside a sealed environment that never connects to the outside world. Your data never leaves. The analysis arrives complete.

01

Complete

Thoris examines the whole case record. Not a curated selection. Not anonymized inputs. Every document, every precedent, every data point your matter contains — examined in full.

02

Sealed

Your case record never leaves your environment. Thoris operates inside an air-gapped architecture that is physically and digitally isolated from the outside world. No exposure. No exceptions.

03

Certain

Thoris does not guess. It does not approximate. It examines, confirms, and returns a complete analysis with mandatory source citations. Every output is traceable to your documents.

Zero-Hallucination Design

Built around one rule

If the system cannot prove it from your documents, it will not say it.

Retrieval-only answering — no free-form guessing
Mandatory source citation on every output
Multi-step verification workflows
Cross-checking against source documents
Refusal modes when evidence is insufficient
Controlled drafting with firm templates
Requires lawyer sign-off before acting on any output
Full audit logs and traceability for every action

Thoris doesn't try to sound smart. It stays correct.

The Platform

Four instruments. One sealed environment.

Thoris Examine

The core case analysis engine. Examines every document, every precedent, every data point in the complete case record. Surfaces risks, patterns, and connections that would take a team of associates weeks to find manually.

Thoris Brief

Automated case summary and synthesis. Generates structured briefs, timelines, issue lists, and risk memos from the examined record — all grounded in your firm's documents, using your templates and style.

Thoris Vault

The air-gapped data environment itself. A sealed, dedicated system where the complete case record lives, is examined, and never leaves. Physically and digitally isolated. Your data. Your hardware. Your control.

Thoris Counsel

The lawyer-facing insight and analysis layer. Surfaces findings, connections, and analytical observations for attorney review. Always analysis. Never advice. The lawyer decides what it means.

Deployment

Installed inside your environment

Thoris is delivered as a dedicated, pre-configured system installed within your firm's environment. You control the hardware. You control the data. Nothing leaves.

Dedicated Hardware

Thoris runs on dedicated hardware within your firm's secure environment. Pre-configured, sealed, and under your control.

Air-Gapped Operation

No internet connection required — or permitted. The system is physically isolated from the outside world.

Role-Based Access

Partners, associates, and staff each see only what they should. Full control over who accesses what.

Full Audit Logging

Every query, every output, every action logged. Complete traceability for compliance and governance.

Your Documents Only

Thoris uses only your firm's documents. No external data. No general training models. Your case record only.

Firm Retains Full Ownership

Your data, your system, your outputs. The firm maintains complete ownership and control at every stage.

Built to meet your confidentiality obligations. ABA Model Rule 1.6 requires reasonable measures to prevent unauthorized disclosure of client information. Thoris satisfies this obligation by architecture, not by contract.

Hard Limits, By Design

What Thoris does not do

These are not missing features. They are deliberate constraints that make the system safe for legal use.

Does not browse the internet
Does not use public data
Does not invent facts
Does not replace legal judgment
Does not bypass lawyer review
Does not train on your data externally

Thoris is a legal analysis engine, not a chatbot.

"Thoris doesn't practice law. It makes certain that the lawyers who do have examined everything first."

Thoris is an analytical instrument. The platform surfaces what is in the case record. Your lawyers determine what it means and decide what to do with it. The analysis is complete. The judgment is theirs.

Nothing left unexamined.

Thoris is currently in deployment with a select group of firms. Inquiries are by direct introduction only.

THORIS

by Mirasys

Four instruments. One sealed environment.

As the platform grows, the naming convention stays clean. Each product extension reinforces the parent brand without diluting it. They all live under Thoris, by Mirasys.

Thoris Examine

The core case analysis engine.

Examine is where every investigation begins. It reads the complete case record — every document, every precedent, every data point — and performs exhaustive cross-referencing across the entire record.

It surfaces risks buried three layers down. It identifies connections between documents that no single associate could find in a reasonable timeframe. It does this for every matter, every time, with the same thoroughness.

Every finding is traceable to a specific document in the original record. Examine does not infer. It does not approximate. It examines.

Thoris Brief

Automated case summary and synthesis.

Brief takes the examined record and produces structured output — case summaries, timelines, issue lists, and risk memos — all grounded in your firm's documents.

It uses your firm's templates, your preferred language, your established style. The output reads like it came from your best associate, because it was built on the same institutional knowledge.

Brief does not generate from general models. Every sentence it produces is traceable to specific documents in the case record. Your lawyers review. They edit. They sign off.

Thoris Vault

The air-gapped data environment.

Vault is the sealed, dedicated system where the complete case record lives. It is physically and digitally isolated from the outside world. No internet. No external connections. No cloud synchronization.

The hardware lives within your firm's secure environment. You own it. You control it. Mirasys configures and delivers the system. Your firm operates it.

Vault satisfies ABA Model Rule 1.6 by architecture, not by contract. Client data cannot be exposed because the system has no mechanism to expose it.

Thoris Counsel

The lawyer-facing insight and analysis layer.

Counsel is how your attorneys interact with the examined record. It surfaces findings, connections, and analytical observations — organized for the way lawyers actually work through a matter.

It answers questions grounded in your documents. "Have we handled something like this before?" "What arguments did we use last time?" "Find language we've already used successfully." Every answer cites its source.

Counsel provides analysis. Never advice. The distinction is absolute. Thoris examines and presents. The lawyer evaluates and decides.

"The most thorough case analysis ever built."

Every instrument in the Thoris platform operates inside the same sealed environment. The case record enters once. It is examined completely. Nothing leaves.

Nothing left unexamined.

THORIS

by Mirasys

Mirasys

Mirasys builds AI analysis infrastructure for industries where the cost of incomplete information is unacceptable.

Thoris is its legal platform — a complete, air-gapped case analysis system built for law firms that demand total examination of every matter they handle. The platform operates entirely within the firm's own environment. No data leaves. No analysis is incomplete.

We exist because every other AI product treats law firms like every other customer. We don't. We build infrastructure designed from the ground up for the constraints, obligations, and standards of legal practice.

The company operates with the same discretion it builds into its products. Mirasys does not seek publicity. It builds systems that earn trust. Not just attention.

Principles

Confidentiality Is Mandatory

We build as if no client data can ever leave the firm. Because it can't.

Hallucinations Are Unacceptable

We build systems that say nothing rather than say something wrong.

Auditability Is Required

Every output must be traceable. Every decision must be explainable.

Systems Must Earn Trust

We don't ship products that need benefit of the doubt. We ship systems that prove themselves.

Correctness before cleverness. Safety before speed. Trust before scale.
