Frequently Asked Questions

10 Q&As on short-form hook writing.

Q1. How long can a short-form hook be?
Depends on video length. 15s → hook by 1.5s, 30s → 2s, 60/90s → up to 3s. Past 3 seconds, distribution weight drops on TikTok, Reels, and Shorts alike.
Q2. How is the 1–10 hook score computed?
Starts at 5. Length fit, numbers, question framing, trigger patterns, payoff promise, urgency wording add points. Generic intros ("Hey guys"), clickbait over-drive, and a 3s+ spoken estimate subtract. Clamped 1–10.
Q3. How are the 30 hook patterns organized?
10 categories (question, shock, twist, urgency, curiosity, emotion, list, contrast, challenge, reaction) with 3 patterns each. Every pattern ships with timing, platform fit, and 3 copy-ready lines in both KO and EN.
Q4. Does hook strategy differ by platform?
YouTube Shorts favors text-caption hooks, Instagram Reels prefers visual hooks with short captions, TikTok lives on text walls, trending sound, and duet / reaction hooks. Use the platform filter to see matching patterns only.
Q5. Why is "Hey guys" / "안녕하세요" penalized?
In muted auto-play feeds, a greeting carries near-zero info density. TikTok, Reels, and Shorts all report it as the single biggest cause of second-1 bounces. Skip the intro, open with the hook.
Q6. How do I use the sample lines?
Each sample has Copy / Score buttons. Score sends the line to the scorer for an instant 1–10 read. Copy writes the line to your clipboard so you can drop it into your script.
Q7. What score should I shoot for before uploading?
7 is "Good". 8–10 is "Excellent" — pair with first-frame caption, visual contrast, and voiceover to convert that into real retention. 5–6 means there's still room to sharpen.
Q8. Do hooks differ between Korean and English?
Structure is the same, phrasing differs. The tool auto-detects language and applies the matching trigger words, length ranges, and speaking rates (~6 syllables/sec KO, ~3 words/sec EN).
Q9. Is my input stored anywhere?
Only in your browser's localStorage — nothing is sent to our servers. Last input restores on revisit. Use "Copy share link" to move between devices.
Q10. What does the pink band on the timeline mean?
Light pink is the max hook window for the selected length (1.5 / 2 / 3 / 3 seconds). The darker pink band inside is the recommended timing for the currently viewed hook pattern. Overlap = high chance your hook lands.
