Know the opposing expert before they testify

One AI agent for each class of expert reads the record and the expert’s own history, and returns the brief a senior expert produces in the first weeks of an engagement: the likely opinion, its weak points, the Rule 702 exposure and the cross. In minutes.

4 sectionsEvery quote checked

Likely opinion. No statistically significant price impact on two of the three disclosure dates.

Weak point. The confounding-news screen drops the strongest date; ask why the earnings call counts and the guidance cut does not.

Rule 702. Estimation window spans a restructuring; courts have limited similar windows.

Settlement range. Directional: their testimony narrows inflation to the first date.

Next: rehearse the cross live against the expert agent.

What a brief contains

One run covers one class of expert on one fact pattern and returns four sections. How the agents work, in detail.

Likely opinion

What the expert will conclude, in their own voice, with the methodological basis.

Cross-examination weaknesses

Ranked, with the question to ask, the deflection to expect, and citations to the case file.

Methodology challenges

The Daubert and Rule 702 attack surface, with the authorities looked up.

Settlement range

How the testimony moves it, directional, with the uncertainty stated.

Measured, not promised

Accuracy is measured blind on real expert reports; the method and its limits are on the Benchmark.
