EU AI Act Article 50 Transparency Audit for Your Codebase

Runs the same checker as our npm package on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Finds the AI call sites, generation code and system prompts that trigger EU AI Act Article 50 disclosure duties - in force since 2 August 2026.
