Answer.

Named jurisdictional law · Illinois HB 3773.

Illinois HB 3773 amends the Illinois Human Rights Act so that using AI in employment decisions in a way that produces discrimination — including on protected classes and via proxies like ZIP code — is a civil-rights violation, and it requires employers to notify employees when AI is used in covered decisions; it takes effect 2026-01-01. Planisphere can measure an employment model's behaviour across protected cohorts to support that nondiscrimination duty; it does not make the legal determination or provide legal advice.

record the duty · seal the receipt · verify offline

Planisphere records each duty event — an output marked, a disclosure shown, a review made — and seals it into a receipt that verifies offline against our published keys. You send hashes, never content. A record is evidence a third party can check; it is not a certification and not a legal determination.
