Why an extension
Most monetization questions happen while watching — you land on a channel and wonder whether it's actually earning. A YouTube monetization checker extension answers that in place: the same subscriber, membership and ad-delivery signals our web checker reads, rendered as a badge on the page you're already on. Until it ships, the web checker is one paste away.
What it will and won't do
Same honesty policy as everything we build: confidence levels instead of a fake yes/no, the full signal list one click away, and no analytics-dashboard bloat. It won't claim to read private data — nobody can — and it won't collect your browsing history.
