California SB 942 — AI Transparency Act

This tool serves as L'AItelier's publicly accessible AI detection tool as required by the California AI Transparency Act (SB 942, effective Jan 1 2026). Files generated through L'AItelier Studio carry an invisible watermark and a C2PA manifest — both detectable here at no cost, with no account required. Watermarks are designed to survive reasonable processing and platform recompression.
