Publishing

Three checks with nothing in common except timing

The Upload Checklist, SEO Checklist, and Chapter & Timestamp Generator each catch a completely different kind of mistake — a missing thumbnail, a weak filename, or a chapter list that silently fails one of YouTube's own formatting rules and renders as plain text instead of the visual scrubber bar. What they share is when they're useful: right before hitting publish, not during editing.

Nothing here calls the YouTube API or needs an account connected — each tool checks your input directly against the platform's own documented rules, the same way the Title Length Checker and Shorts Safe Zone Checker do elsewhere in this toolset.
