Short answer

How can I use AI to find counterarguments?

You provide your legal theory, and the AI uses specialized tools to hunt for flaws, opposing precedents, and logical gaps. This process turns your agent into an adversarial partner that exposes vulnerabilities. You'll see exactly where your logic breaks down.

The outcomes.

Where your arguments land.

The AI processes your input through four distinct adversarial stages.

WEAKNESSES

Identified logical gaps

The AI finds contradictions in your reasoning. You get a list of specific points where your argument fails to hold up.

OPPOSITION

Strongest opposing views

The agent simulates the most aggressive version of the opposing counsel. It presents the exact arguments they will likely use against you.

PRECEDENT

Conflicting case law

The AI looks for legal authorities that undermine your current stance. You receive a summary of cases that work against your position.

HUMAN

Final strategic review

The AI flags the most dangerous vulnerabilities. You must decide how to pivot your strategy or shore up your evidence.

The workflow

What your AI does when the issue arrives.

The AI doesn't just agree with you. It actively works to dismantle your position to ensure it is actually solid.

  1. Deconstruct your theory

    The AI breaks your argument into individual claims to see which ones are the most fragile.
