A canon is an authoritative text made executable: the pinned source, the rules written from it, and the questions it answers. It can be added to an application or agent as a versioned dependency, so when the source changes you update one package instead of retraining the AI model.

How are results reproducible?

Results are reproducible because the model version, question, facts and date are all kept on record. When you replay a run with the same inputs, it repeats exactly and a checksum confirms the match. Earlier results can replay on the edition they originally used.

What sources are currently modelled?

Available models cover laws and treaties including EU Regulation 261, GDPR, Code civil, BGB, and Codes of Kazakhstan; standards and protocols including IEC 60364, NEC, ISO 13616 IBAN, HTTP semantics and OAuth 2; and reference texts including Incoterms and GUM measurement uncertainty.

Arxo serves products and AI agents that need to answer questions depending on rules; calculation and compliance software that already computes payouts, contributions or deadlines; and legislative and legal departments that need to check drafts and acts hold together on real cases.

Ahrefs Domain Rating reported 28 Oct 2026, restated 25 Oct 2026.

A platform that runs versioned, executable models of laws and standards, delivering reproducible results with grounds, rules, passages and editions.

Overview

Screenshot of the Arxo homepage — A look at arxo.io

Arxo keeps one executable, versioned model of laws and standards that applications, AI agents and compliance software can call. Instead of re-implementing rules in spreadsheets, services and prompts, teams use a single model tied to its authoritative source. Each result shows the rules applied, the passages from the source and the facts used, along with the edition it ran under. Users can change facts and re-run cases to see how results change, and earlier results can replay on the edition they originally used. The platform serves products and AI agents, calculation and compliance software, and legislative and legal departments.
