Detailed Review
Noxtua starts from a question that matters more in continental Europe than in the United States: which national law, and whose published commentary, is the answer drawn from. The product is sold in country editions, with the website listing Germany, Austria, Switzerland, Poland, the Czech Republic, Slovakia, Bulgaria and Sweden, each paired with a local legal publisher.
The contracting company is Noxtua AG, registered at the Charlottenburg commercial register in Berlin (HRB 202784 B). Its security page puts data centres in the EU and Switzerland and names IONOS and Deutsche Telekom as infrastructure partners.
Answers Built on Publisher Content
Noxtua states that its research layer reads full texts from 19 legal publishers in eight countries, and the home page quotes more than 210 million searchable documents and 15.8 million court decisions. For a lawyer in Munich or Vienna that means citations to commentary and case law that the model did not invent.
Beyond research, the workspace has projects that hold a whole case file, an editor that works on Word files directly, and skills that you define once and apply automatically to later matters.
Two Model Tiers, Two Hosting Positions
The Minerva Agent gives access to closed-source frontier models from international providers while the durable data stays on Noxtua's European-controlled infrastructure. The Athena Agent hosts the entire system on sovereign European infrastructure and is aimed at the judiciary and public administration.
In both tiers, Noxtua says inputs and outputs are not stored by the model provider and not used for training, and that conversation history sits in encrypted storage with IONOS and Deutsche Telekom.
Certifications Listed
The security page lists ISO 27001, ISO 42001, ISO 9001, ISO 27017 and ISO 27018, a BSI C5 attestation, a SOC 2 report and a TISAX label, and points to a trust centre for the documents. It also describes the design as meeting the confidentiality duties behind lawyers' professional secrecy under section 203 of the German criminal code.
Limitations to Consider
There is no public price list, so a budget comparison with Legalfly or Genie AI needs a conversation with sales. The Minerva tier routes prompts to international frontier models, so a firm that wants the entire stack on European infrastructure has to choose the Athena tier. The strongest content is tied to the country editions, which means coverage outside the listed jurisdictions is not the selling point.
Who Should Use Noxtua
Law firms, courts-adjacent bodies and in-house teams in Germany, Austria, Switzerland and the other listed countries that need cited research and drafting under professional secrecy obligations.
