Only hallucination-free Legal AI that reasons like a lawyer

Most lawyers settle for the best citation they can find — not the best one they should have. MikeROS changes that. It’s the only Legal AI that reasons like a lawyer: reasoning from the nature of your case to surface the authority you need, then building the reasoning chain step by step, with zero hallucination in the reasoning and every link locked to verified law.

Hallucination-Free
The reasoning, citations, and conclusions are derived by a symbolic engine, not generated by an LLM — so on covered law they cannot be invented. Where a question falls outside scope, MikeROS says so rather than guessing.
Structural Search for Citations
MikeROS finds authority by the underlying structure of your case, not just its surface wording — surfacing the on-point precedent that ordinary search overlooks.
Reasoning Chains
It builds the argument the way a lawyer does — step by step, each link locked to a verified rule and a real authority, with a complete trace you can follow and defend.

Legal AI that invents citations is a malpractice risk

The hard part of legal AI isn’t writing fluent prose — it’s being right. Tools built on large language models are designed to predict the most likely next words, not to find the correct answer, so they will confidently cite cases that were never decided, misstate the holdings of the ones that were, and wrap it all in reasoning that reads as authoritative but cannot be checked. A 2025 Stanford and Yale study in the Journal of Empirical Legal Studies found hallucinated or erroneous output in 17–33% of answers from the leading commercial legal-AI tools. In litigation, a single fabricated citation can sink a filing — or a career. “Usually right” is not a standard the profession can work to.

You can’t fully trust the legal advice you get from your current AI.

Your team burns billable hours double-checking AI research it can’t verify.

On-point precedents get missed, because the AI can’t reason the way a lawyer does.

These aren’t workflow problems. They’re a fundamental limit of how general-purpose legal AI is built.

The difference is provability

MikeROS keeps the fluency of an LLM for understanding the question, but moves every decision onto a deterministic reasoning engine that can show its work.

Generic legal AI

  • LLM predicts the answer
  • Citations may not exist
  • No proof of correctness
  • Hope it's right

MikeROS

  • LLM understands the question
  • Reasonex reasons deterministically
  • Every citation verified against live databases
  • Provably correct, with a full audit chain

Read. Reason. Prove.

Three layers, each doing only what it is good at — so the reasoning is necessary, not probable.

Read

Neural language understanding turns a plain-English legal question into structured legal intent. The LLM listens — it never decides the answer.

Reason

The Reasonex engine applies jurisdiction-specific rules through symbolic, deterministic inference — constructing a formal logical proof rather than a probable guess.

Prove

Every output ships with a complete audit chain: the answer, the citation, the paragraph, the applicable rule, and the full reasoning behind it.

MikeROS architecture: a plain-English legal query passes through a neural perception layer, into a symbolic reasoning layer that maps factual patterns, legal conditions and outcomes, and out as a deterministic response with a zero-hallucination, auditable reasoning chain
Plain-English query in, deterministic legal opinion out — the reasoning happens in the symbolic layer, never the language model.

Where litigators put it to work

Contract review

Clause-by-clause analysis with the reasoning shown for every flag.

Precedent research

Structural fact-pattern matching that finds on-point cases, not keyword neighbours.

Procedural computation

Deadlines and rules-of-court calculations derived directly from the governing rules.

Document drafting

Court document drafting with forms compliance built in.

Compliance verification

Regulatory checks traced end-to-end against the applicable framework.

Training & QA

Associate training and quality review with transparent, reviewable reasoning.

Why it holds up in practice

Verified citations only

Every citation is checked against live legal databases. If a source can’t be verified, it isn’t cited.

Jurisdiction-native rules

The rules engine reasons over the actual rules of court for each jurisdiction — not a generic approximation.

Full audit trail

Every answer carries its logical proof chain, so the reasoning can be checked, defended, and relied upon.

Data stays in-jurisdiction

Data residency is enforced by the architecture, not bolted on as a policy.

Deploy it the way that fits your firm

Standalone app

A web-based interface your team can use directly — no integration required.

REST API

Programmatic integration with your practice-management and document systems.
