X Hook Tester
Paste your tweet hook → get pattern + score across specificity, brevity, conviction, curiosity. Fix list included. Pure pattern-matching (not AI) — same input always gives same score.
Common questions
What is a tweet hook?+
The first line of your tweet — the part visible in the feed before someone clicks 'show more'. The hook is 80% of a tweet's engagement leverage. A great hook + mediocre body outperforms a mediocre hook + great body.
What patterns does the tester detect?+
5 common viral patterns: contrarian claim ('Most people think X — they're wrong'), specific number ('$12k MRR in 90 days'), curiosity gap ('Here's why:'), personal stake ('I rejected a $40k offer'), and framework ('5 rules for hiring'). The tool flags 'unidentified' if none match — usually a sign the hook needs a clearer pattern.
How does the scoring work?+
Four 25-point dimensions: specificity (has numbers/named examples), brevity (8-20 words is ideal), conviction (no hedges like 'I think'), and curiosity (does it earn the click into the rest). Total score 0-100. 80+ is strong, 60-80 is workable, below 60 needs rewriting.
Is the scoring deterministic — same input = same output?+
Yes. The scoring is pure pattern matching + rule-based scoring, not AI. The same hook always gets the same score. This lets you iterate confidently — change one word, re-run, see the score shift.
