One Engine Per Jurisdiction, Not One Global Model

    Generic AI tools blend jurisdictions together and invent citations. Cassandra does the opposite: each country runs against its own primary-source corpus, its own regulator guidance, and its own citation conventions, so an answer is checkable against the statute it names.

    Where a regime is in transition — India's Income-tax Act 2025, Brazil's CBS/IBS consumption tax reform, or Pillar Two adoption across the EU, UK and Gulf — Cassandra surfaces the transition rather than silently picking one regime.

    • Every output names the jurisdiction, the legislation, and the regulator guidance relied on.
    • Cross-border work combines national engines with the applicable double tax agreement and OECD commentary.
    • All outputs require review by a practitioner qualified in the relevant jurisdiction.
