Hook Score
You have about two seconds. Paste the first line of your short-form video and get a 0-100 score with specific fixes. Transparent rules, not a black box.
Heuristic guidance based on common short-form patterns: length, proven openers, voice, specificity, curiosity, and salesy penalties. It doesn't predict views. Want real data? See the Post Lab. Also on the API: POST /api/v1/hook-score.
