Declare your AI provenance
An open standard for declaring AI tool usage in any open source project. Attaches to any license. Works with any governance engine.
The Gap in Open Source
When you open source code today, your license covers copyright and usage rights. It does not cover AI authorship.
A consumer of your code cannot tell if it was written by a human, assisted by Copilot, or generated entirely by Claude Code. This opacity causes issues for compliance, insurance, and supply chain risk. The AI License Notice solves this by making AI provenance explicit, transparent, and machine readable.
