The AI tax research platform

Purpose-built for Belgian tax professionals. Every answer is traceable, scored, and grounded in real sources.

Verified sources

Every citation links to real legislation, rulings, and circulars. Nothing fabricated, everything checkable.

Always current

Continuously updated legal database, not static training data months behind reality.

Authority ranking

Knows Constitution outranks a circular. 13-level hierarchy ensures the right source wins.

Jurisdiction-aware

Distinguishes Flemish, Walloon, and Brussels rules. No accidental cross-border mixing.

Temporal versioning

Ask about 2019 rates, get the 2019 law. Reason about any point in time.

Confidence scoring

Every answer carries a trust score. Know when to rely on it and when to dig deeper.

Not a chatbot with a tax plugin

A specialist research platform engineered from the ground up for Belgian tax law.

1

Ask in any language

Query in Dutch, French, or English — find provisions in any language, with legally correct terminology across all three.

2

Get a scored answer

Every response shows its confidence level, the sources it drew from, and which jurisdiction applies — so you immediately know where you stand.

3

Verify the sources

Click through to the original legislation, ruling, or circular. If we're not sure, we say so — because "probably right" isn't good enough in tax.
