Paste the exact first line of a short-form video and receive a transparent writing diagnostic. The analyzer checks the words you provide; it does not inspect a video or connect to a social platform.
Writing diagnostic
Check a draft hook
Review clarity and structure before you record. The score is a transparent checklist, not an audience prediction.

Use these as editing prompts. Keep only claims that are true and supported by the video.
This diagnostic does not access platform analytics and cannot forecast performance.
How the diagnostic should be used
Treat the result as an editing checklist. A strong opening usually tells the right person why the next few seconds matter, without revealing so little that the sentence becomes empty clickbait. The analyzer rewards concise wording, direct audience relevance, useful specificity, and readable punctuation. It flags absolute or sensational terms that often create a promise the video cannot support.
The score is not a prediction
ReelsHook does not receive watch-time data, audience history, distribution signals, or creative context. It cannot measure performance. The score reflects only observable properties of the written opening. Lighting, delivery, visual change, sound, subject demand, timing, and the quality of the payoff remain outside the score.
Review the complete opening
A spoken sentence is only one part of the first three seconds. Check whether the first frame shows the subject, whether on-screen text is readable without sound, and whether the next sentence starts delivering the promised value. An excellent line attached to an unrelated first frame can still confuse a viewer.
