What makes this different
Built from scratch for tax
Not ChatGPT with a tax plugin. A dedicated system that reads legislation the way you do — structurally, in context, with attention to hierarchy and amendments. It gets smarter with every question your team asks.
Always the right year
Ask about 2019 rates, get the 2019 law — not today's version. The system knows which rules were in force on the date that matters: income year, assessment year, or entry into force.
Tells you when it's unsure
Every answer comes with a confidence score. When sources conflict, the system flags it. When evidence is thin, it says so. You always know how much weight to give the answer before you advise your client.
From question to reasoned position
Three steps to a sourced, scored answer — in the time it used to take to open the first document.
Ask in any language
Query in Dutch, French, or English — find provisions across all three, with legally correct terminology in each.
Get a scored analysis
Every response shows its confidence level, the sources it drew from, and which rules apply for the year in question — so you immediately know where you stand.
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.
