This is a real screen recording of the live tool: a weak hook is typed in, submitted, and scored — you can watch the genuine 56/100 structural-fit score, the feature table behind it, and the specific fixes the tool returns.
Nothing here is stock footage and no part of the interface is synthetic. It is the real page, in a real browser, doing real work.
What the score means: it measures how closely a hook's structure matches the 600-hook corpus. It does not predict views, clicks or revenue — the corpus carries no engagement data.
