Dualmark
Markdown dual-version infrastructure for AI-readable marketing websites
About Dualmark
Dualmark provides Markdown dual versions for website pages: browsers continue to receive the existing page, while AI agents get clean Markdown through the same URL. At the edge, the system identifies known clients through HTTP content negotiation, Accept headers, and User-Agent, without duplicate URLs, JavaScript, navigation, or cookie banners. It supports no-install scoring, CI checks in GitHub Actions, and blocking merges when the page consistency score falls below a threshold.
