The Hook Analyzer reads your opening the way a scrolling viewer does: is it clear, does it open a question, and is there a reason to stay past the first line? Four scores, each with its reason — and the line to fix first. Here is how to get the most out of a read.
Scores are for the words a viewer hears. Paste the spoken opening — not a summary of the video, not the title. Two sentences is plenty.

A hook with high clarity and low curiosity doesn't need to be clearer — it needs a question. Change one thing, re-run, and compare; changing everything at once hides what worked.
Rewrite the whole hook because the overall score is middling.
Curiosity is the low score → add the open question, keep the rest, re-check.
Analyses list real videos on the same topic that beat their channel's usual views. Read their titles and openings — if yours promises less than theirs, that's your gap.
Publish because the score went up by three points.
Compare the promise in your line to the top real video on the topic, then decide.
