Demarker runs on your own machine — the client starts it, so there is no endpoint to ping. 32 installs a week from npm. Last commit 13 Oct 2026.
Identify what an AI image carries (marks, metadata, watermarks), then clean it.
Today is the operative word: we check Demarker every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
