Why your hook score matters

TikTok's algorithm decides in the first 2–3 seconds whether to push your video to more users. A high-scoring hook means higher watch-through rates, which directly leads to more reach. This tester rates your existing hook on ten criteria — pattern interrupt, emotional trigger, curiosity gap, specificity, and more — and shows you exactly what to improve.

How to use the Viral Hook Tester

Paste the first line of your planned video — the spoken opening or on-screen text. The AI scores it from 1 (weak) to 10 (extremely viral) and provides three rewritten versions with concrete explanations of each improvement. Copy the best version directly into your script.

What makes a TikTok hook score 9 or 10

Top hooks combine at least two of: a specific number or claim, a named emotion or fear, a curiosity gap that can only be resolved by watching on, or an identity call-out ("if you do X, this is for you"). Generic openers like "Have you ever…" or "In this video I will show you…" consistently score low because they lack pattern-interrupt power.
