What does the law say? And what did it say before that?
Laws don't appear out of nowhere — they evolve. Lawstronaut tracks the full history of legislation across 150+ countries so your product or AI agent can show not just the current version of a law, but every version that came before it, what changed, and when.
- Full version trails
- Article-level change tracking
- Point-in-time retrieval
- 168+ jurisdictions
- Audit-grade provenance
Knowing what the law says today is the starting point — not the finish line.
If you're dealing with a dispute, you need to know what the law said on the day the dispute started. If you're doing a compliance review, you need to know whether an obligation existed two years ago. If you're advising a client, you need to understand why a clause was written the way it was — because the courts sometimes care about that.
Most legal tools only show you the current version. Lawstronaut gives you the whole story.

Every version, from first publication to today
The complete timeline of any law — when it was first passed, every time it was amended, and what it looks like now. All in one place, organized, and easy to navigate.
Exactly what changed, in plain terms
When a law is updated, Lawstronaut shows you the specific sentence or paragraph that changed — the old wording, the new wording, and the date it changed.
What the law said on any specific date
Need to know what a regulation said on 15 March 2021? Lawstronaut retrieves the exact version that was in force on that date, from an official source, with a full audit trail. Useful for litigation, regulatory investigations, and compliance checks tied to specific time periods.
When laws were replaced or cancelled
Track when a law was replaced by new legislation or stopped being in force — so your product never cites something that no longer has legal standing.
