Tax research that shows its work
AI-powered tax research built for Belgian professionals. Confidence-scored answers. Transparent reasoning. No black box.
The problem with AI tax tools today
General-purpose AI gives you confident answers to tax questions. That's exactly what makes it dangerous.
Fabricated sources — cites rulings and articles that don't exist, with no way to verify
Outdated knowledge — training data months or years behind, while tax law changes constantly
No hierarchy awareness — treats a blog post and a Court of Cassation judgment the same way
Jurisdiction-blind — mixes Flemish, Walloon, and Brussels rules, as well as Netherlands and France, without distinction
Temporal blindness — Ask "What was the deduction limit in 2019?" and get today's answer. No ability to reason about the law as it existed at a specific point in time.
False confidence — Presents every answer with equal certainty, whether backed by 10 sources or pure speculation. No way to know when to dig deeper.

Why our pilot users trust Auryth
Confidence-scored answers. Transparent reasoning. No black box.

No black box
See how our AI reasons. The sources, the logic, the limitations — all visible
Jurisdiction-deep
Built from the ground up for Belgian tax law — three regions, bilingual legislation, local source hierarchy
Purpose-built for Belgian tax law
Not a general AI with a tax plugin. A specialist research platform engineered from the ground up.
Authority hierarchy
Constitution > Laws > Royal Decrees > Circulars > Doctrine — the system knows which source wins when they conflict.
Temporal versioning
"What was the corporate tax rate in 2019?" — answered with the law as it was then, not as it is today.
Trilingual NL/FR/EN
Query in Dutch, French, or English — find provisions in any language. With legally correct terminology across all three.
Source transparency
Every answer shows its sources. Every claim can be verified. If we're not sure, we say so.
"In tax, 'probably right' isn't good enough."
We'd rather give you an honest "we're not sure" than a convincing answer built on thin evidence. That's our promise — not that we're always right, but that you'll always know where you stand.
