For LATAM commodity charterers

Stop overpaying on demurrage.

Charterers overpay 8–15% on demurrage invoices from greek and japanese owners. Our AI-native audit platform extracts your charter parties and SoFs, recomputes laytime with a deterministic 80-rule engine, and generates arbitration-ready evidence — in minutes, not weeks.

No upfront. Pilot pricing: 20% success-fee on recovery. No recovery, no fee.

Built for arbitration

Every output traceable. Every rule sourced. Every calculation reproducible.

Deterministic engine (CP#3)
Numerical calculation is pure TypeScript — no LLM in the calc path. Audit scriptcheck-deterministic-calc.tsenforces this in CI. Same input always produces same output.
Citation chain (CP#4)
Every fact extracted from your documents carries a verbatim quote + page + paragraph reference. Citations propagate through the engine into the audit PDF and dispute letter. Tribunal verifiable.
Multi-source rule validation (CP#5 v2)
Each of the 80 laytime rules is backed by ≥7 public-domain sources: Schofield "Laytime and Demurrage" 8th ed, Cooke "Voyage Charters" 5th ed, BIMCO standard clauses, LMAA awards, and Perplexity-validated authorities.
Data ownership (CP#8)
Your CPs and SoFs are yours. Export anytime in JSON + original PDFs. Delete on churn with 30-day SLA. Never used for training without explicit opt-in.
