moot • mock • adversarial

Pressure-test your case before opening day.

A full adversarial simulation: an AI tribunal, an AI opposing counsel, and witnesses who push back. Run a moot at 3am the night before — or rehearse a six-day arbitration with the same pressure your associates will feel in the room.

Modes

Three simulations, one engine.

Trial moot

Common-law trial: opening, examination-in-chief, cross, closing. Bench-tier AI judges with documented dispositions — pick the bench you'll actually face.

EN-AU · EN-UK · EN-US · EN-SG

Arbitration

Multi-day institutional arbitration — ICC, SIAC, HKIAC, SCC, CIETAC, SCAI. Tribunal compositions modelled on real chair dispositions and known concurrences.

Rapid moot

30-minute pressure test the night before opening. Drop in your written submissions — get five most-likely cross questions, three weakest pleadings, and one ambush you missed.

Live transcript

Every word, every objection, scored.

The simulation runs in your browser like a real proceeding — voice or text. Every turn is timestamped, every objection ruled, every question annotated for risk: leading, hearsay, beyond scope, calls for speculation.

  • Voice or text. Speak it like you'd argue it. Or type at 3am while everyone's asleep.
  • Real-time objections. AI opposing counsel objects when you'd object — leading, hearsay, compound, argumentative.
  • Bench rulings, on the record. Each objection gets ruled on, with reasoning. Compare to your forum's published rulings.
  • Scrub-back to any moment. Replay your weakest exchange. Watch yourself walk into the trap. Try again.

Mr. Hall, can you describe the moment you first reviewed the amendment to paragraph 14?
04:18:31
Witness · J. Hall
I... believe it was sometime in early March, possibly the second week.

Mr. Hall, when you say "early March" — isn't it true you reviewed it on March 11th, the day after the share price dropped?

Scorecard

The number you actually want: are we going to win?

Each session ends with a scorecard. Not a grade — a forecast. Confidence on liability, expected award range, tribunal alignment, weakest pleading. Calibrated on 28,000 published awards and the audit-grade reasoning that produced each one.

  • Tribunal-aware. Different chairs read the same brief differently. So does our model.
  • Damages calibrated. Award range comes from comparable awards, not a guess. Citations one click away.
  • Day-over-day delta. Did your cross of the CFO move the needle, or just feel good?
  • Settlement guidance. When the numbers tell you to settle, ZAAN says so. Quietly.
Witness prep

Find the question that breaks them.

Upload deposition transcripts. ZAAN models how each of your witnesses behaves under pressure — where they hesitate, where they over-explain, where they contradict. Then it generates the cross-examination most likely to land.

  • Per-witness profile. Hesitation patterns, over-explanation triggers, factual blindspots — modelled from prior testimony.
  • Question stack ranked by lethality. Ten questions, scored 0–10. Practice the top three until they're muscle memory.
  • Roleplay both sides. Be the cross. Be the witness. Switch in one click.
  • Privileged. Locked. Local. Witness profiles never leave your tenancy. Air-gap mode for state-secret matters.

Step 02

Choose forum

Pick the tribunal — ICC, SIAC, NSW Supreme. Pick the chair, or let the model pick a comparable.

Step 03

Run the moot

Argue. Cross. Object. The AI tribunal rules in real time. Voice or text, alone or with your team.

Step 04

Scorecard & replay

Confidence forecast, weakest pleading, three things to fix tonight. Replay any moment, try a different line.
