Deadline Engine

Deadline Engine. Calculate legal deadlines instantly.

A focused legal infrastructure product that calculates court filing dates instantly, reduces manual checking, and gives lawyers confidence before a deadline becomes urgent.

Deadline Engine turns court rules into an immediate calculation. It is built for litigators and in-house counsel who need a reliable answer without manually counting days across procedural rules.

It exists because it proves the Thesmios operating model in a narrow legal workflow: take slow, expensive, error-prone manual work and replace it with precise infrastructure that is faster and cheaper to use.
