Prove what the law said — and when
Most legal questions are about today. Lawstronaut MCP's Evidence Mode is for the ones that aren't. When a dispute arose, what did the law say on that specific date? When an obligation was assessed, was the regulation already in force? Evidence Mode retrieves the exact legal text as it stood on any given date — with a verifiable trail back to the official source.

When the current version of the law is not the right answer
Litigation, audit, regulatory investigation, and compliance reviews all ask the same kind of question — not what the law says now, but what it said then.
What did this regulation say on the date the breach occurred? Was this obligation already in force when the decision was made? Which version of this law applied during the period under review?
These questions require more than a correct answer. They require a provable one — with a source, a date, and a version that can be independently verified.
Most legal tools only show the current version. Lawstronaut Evidence Mode gives you the whole trail.
Point-in-time retrieval, with the trail to prove it
The exact law as it stood on any date
Retrieve the authoritative text of any law, regulation, or provision as it stood on any specific date — not today's version, not an approximation. Every retrieval is timestamped and traceable back to the official source.
A verifiable trail back to the source
Every document includes the official source link, publication date, version identifier, issuing authority, and the date it came into force. Your agent does not just return an answer — it returns proof.
Every version from first publication to today
The complete timeline of any law — every amendment, every change, every version — with the exact differences between each one, the date each change took effect, and the authority that made it.
Track exactly what changed and when
Know not just that a law changed, but which specific provision changed, what it said before, what it says now, and when the change took effect — tracked at the article level so the answer is always precise.
Built to survive scrutiny
Evidence Mode is designed for outputs that need to hold up — in a courtroom, a regulatory investigation, an audit, or regulator correspondence. Every answer includes everything needed to verify it independently.
