Turn your notes into a full YouTube description with an opening, chapters, links and hashtags, checked against the 150-character fold and YouTube's chapter rules as you type.

Thumbnails, banners, end screens, and every other file YouTube has a size limit for. Grab what exists, check what you made against the spec.

Drop your thumbnail and title into a feed of real outlier videos from your niche, on desktop or mobile, light or dark, and see whether it stands out before you publish.

The arithmetic behind the dashboard: engagement rate, view-to-subscriber ratio, RPM and CPM earnings, and what a milestone actually needs.
