Hook Analyzer
Paste the first 1–2 sentences of your video, post or email and get an instant engagement score. The analyzer checks for six proven hook triggers — curiosity gap, emotional trigger, specificity, question, negation pattern and pattern interrupt — shows which fired, and gives specific suggestions to push the score higher.
How to use
- 1
Paste your hook
Type the opening 1–2 sentences of your content. The analyzer works best on 8–30 words — the typical length of a video or email hook.
- 2
Read the total score
The top-right panel shows a 0–100 score with a colour bar (red < 50, amber 50–75, green > 75). Below it, see how many of the six triggers fired.
- 3
Review the trigger badges
Each badge shows whether a trigger fired. Click a card in the breakdown section to see exactly which words or patterns matched.
- 4
Apply the suggestions
The Suggestions panel lists concrete edits — add a number, open with an imperative, use the negation pattern, etc. Apply them and watch the score climb.
Common use cases
- Test your YouTube short hook before recording.
- Audit the opening line of cold email outreach.
- Coach a team on what makes a strong video hook.
- Generate variants of a hook and pick the highest-scoring one.
Limitations
- The score is a heuristic based on common copywriting frameworks (PAS, AIDA, curiosity-gap). It does not predict actual engagement — delivery, audience and topic matter more than any formula.
- The trigger word lists are English-only and not exhaustive. A brilliant hook that uses none of the listed words can still work — the score is a sanity check, not a ceiling.
- The named-entity detection is naive (capitalised words). It will miss lowercase proper nouns and over-count sentence starters; the list is filtered to common false positives but may still misfire.
- Hooks longer than ~30 words lose viewers before the payoff on most platforms. The length penalty rewards concision but cannot detect whether your specific hook is genuinely too long.
