Frequently asked
What counts as a "voyage"?
One voyage = one Charter Party + Statement of Facts pair processed by the engine. Output (audit PDF, dispute letter, LMAA bundle, Letter of Protest) generated from the same voyage do not count again.
Can I cancel anytime?
Yes. Cancel from the Stripe Customer Portal accessible via your billing page. No cancellation fee. Plan downgrades to Free at the end of the current period.
How does Demurrage.IA compare to Veson IMOS or Voyager Portal?
Veson IMOS is enterprise-only ($150K+/year). Voyager Portal is $50K/year flat, sales-led. Demurrage.IA is the first self-serve, AI-native demurrage platform with LMAA-cited dispute letters and LATAM jurisdictional packs — usable bottom-up from a single analyst (Free tier) up to enterprise fleet (Growth + Enterprise).
Is the engine really deterministic?
Yes. Calculation is pure TypeScript (CP#3) — same input always produces same output. AI is used only for extraction (CP/SoF parsing) and natural language generation (dispute letter prose). 36/36 golden fixtures pass; 189 rules codified; 48 LMAA precedents in corpus.
Do you support PT-BR and ES?
Yes. Dispute letters generated in PT-BR for Brazilian charterers and ES for Argentine/Chilean/Peruvian/Colombian. Jurisdictional rule packs for BR, AR, CL, PE, CO, UY codified.
