Frequently asked questions
Does a high score guarantee my video goes viral?
No — and any tool that promises that is lying. This is a heuristic checklist: it measures whether your hook follows patterns that correlate with retention (short, curiosity-driven, no filler). Delivery, timing, topic, and luck still decide the outcome. Use the score to kill weak openers before you film, not to predict the algorithm.
What does the checker actually look at?
Six weighted checks: under 12 words (20 pts), opens with a question/number/"you" (20 pts), a curiosity-gap word (15 pts), no clickbait ALL-CAPS (15 pts), a CTA-free opening (15 pts), and no filler greeting (15 pts) — 100 points total.
My hook scored low but I like it. Should I change it?
Read WHICH checks failed first. A failed "filler opener" is almost always worth fixing; a failed "curiosity word" might be fine if your hook earns curiosity another way. The breakdown is the point — the number is just a summary.
Can I check hooks in other languages?
The checklist is tuned for English (curiosity words, filler phrases, question words). It will still score length, caps, and structure for other languages, but take the word-based checks with a grain of salt.
How is this different from the Viral Hook Generator?
The generator writes hooks for you from proven patterns; this checker grades a hook you already wrote. Use them together: generate options, then score your favorites and film the winner.
Does my hook leave my device?
No. Scoring runs 100% in your browser against built-in rules — nothing is uploaded to any server, and nothing is stored.
