How to Build a California-Compliant AI Detection Tool for Free

Building an AI detection tool? California just made it mandatory (and free). 🔍

The Mandate

Under SB 942, covered providers must offer a tool to detect their own AI-generated content. This tool must be free to the public.

Building It on a Budget

You don't need to invent new tech.

  • Leverage Metadata: If you are embedding C2PA metadata (as you should be), your detection tool just needs to read it.
  • Open Source Libraries: Use libraries like C2PA-JS to build a simple web interface.

The "False Positive" Trap

Ensure your tool clearly states its limitations. No detector is 100% accurate. Disclaimers are your friend.

Conclusion

Compliance doesn't have to be expensive. Use open standards to meet the requirement efficiently.
