Legal AI is only as good as its last source
Most legal AI tools work from a static corpus — accurate the day it shipped, stale ever since. Regulations get amended. Guidance gets updated. Court decisions shift the interpretation of statute. Your tool doesn't know.
That's not a model failure. That's a grounding failure. And the fix isn't a better model — it's a better source.
Not a training set. Not a crawler. Legal data infrastructure.
We built the pipeline behind the corpus: continuous ingestion from 1120+ official portals, normalization into a consistent schema, change-detection at the article level, and provenance on every document returned.
Every law, in every country, always up to date
Legislation, regulations, guidance, and case law from 181+ jurisdictions — collected from official government sources, structured, updated daily.
Know exactly what changed and when
Not "this document was updated." The exact sentence that changed, the old wording, the new wording, and the date.
Every answer traceable to the source
Citation, timestamp, and a link back to the official document — in the same turn.

Built for legal-tech builders, AI agents, law firms, and the teams behind them
Legaltech platforms shipping AI to lawyers and in-house teams — you need defensible answers and an always-current corpus you don't have to maintain.
Compliance and GRC teams running against regulatory change across every country you operate in — without a researcher per jurisdiction.
AI builders in regulated industries — finance, health, data protection. Your agent's answers need to survive an auditor or a regulator.
Law firms building AI into their practice — give your agents and internal tools authoritative, multi-jurisdictional coverage your clients can rely on.
Internal legal ops automating advice on a global footprint.
Built by the lawyers behind filerskeepers
Over a decade in commercial law and compliance. Mentioned in Chambers, ranked in Legal 500. We have sat on the lawyer side of bad legal data — we know exactly where AI agents fall over without it. That's why we built the infrastructure first.
Lawstronaut gives our team access to current, source-verified legal information across jurisdictions we couldn't easily track on our own — which has made our research faster and more defensible.
