Capabilities

Everything you need.
Nothing you don't.

Answers backed by the actual law.

Every claim traces to a paragraph, an act, a directive.

14 jurisdictions, one platform.

We have the greatest legistlation database in Europe.

Your data, your access logs, your knowledge space.

Invoices, contracts, client files, read and cited, never just quoted.

Your firm's method, in every answer.

Upload playbooks, memos and standard positions. azta cites them beside the law, so every colleague answers the way the firm answers.

Every answer, defensible.

Full audit trail. Source links. Reproducible reasoning. For the moment a partner, a client or a regulator asks how you got there.

Fast, accurate,
always current.

Minutes, not hours

Cited answers in minutes.

The most accurate on the market

Verified by practising advisors.

A knowledge base that updates itself

New legislation tracked and indexed daily.

How it works

We don't hand you an answer.
We show you the reasoning.

Ask in your own words

Cross-border, sector-specific, obscure — no question is too technical and no question is judged.

azta searches the sources

Statutes, directives, official guidance, professional statements — across every jurisdiction in scope.

Evidence is assembled

Millions of rows of legal data cross-referenced into the specific answer your case requires.

You get a cited answer

Paragraph numbers, primary sources, jurisdiction flags. Delivered in about a minute.

The detail matters

Comprehensive research, in under a minute.

Our research engine sweeps every relevant source: legislation, professional commentary, official guidance, and assembles the answer in the time it takes to open a file. The knowledge base updates continuously, so no answer is ever based on last year's rules.

Everyone likes a saving

Hours back, margin up.

Firms using azta report 20–30% less time spent on routine research — time that either goes back to the client or back to the bottom line. For smaller firms, it\'s the equivalent of hiring a cross-border specialist without the cost.

What is azta and how does it work?

azta is an AI research tool purpose-built for tax and accounting work across 14 EU jurisdictions. Ask any question in plain language; azta searches primary legislation, official guidance and professional commentary, then returns a cited answer with paragraph-level references. Every answer is traceable to its source.

Does azta replace tax professionals?

No. azta replaces the hours professionals spend hunting through statutes — not the judgement they bring to a case. Think of it as a very fast junior researcher who never forgets a source.

Can I upload my firm's own knowledge base?

Yes. On Enterprise, azta can be pointed at your internal playbooks, client memos and bespoke guidance. Your data stays on your instance, is never used for training, and appears in answers alongside primary legislation.

How is azta different from ChatGPT, Harvey or Legora?

ChatGPT isn't in the same category as it hallucinates citations. Harvey and Legora are both strong legal AI platforms, built for general legal research in English-speaking and Nordic markets. azta is built specifically for tax and accounting work across 14 EU jurisdictions, with the primary legislation, official guidance and local registries a tax advisor actually needs. Same category, sharper focus.

Are you still hiring?

Always — especially experienced tax advisors and legal engineers. See the careers page for open roles.
