Hook Strength Analyzer

Paste your TikTok, Reels, or Shorts hook. We grade it 0–100 on specificity, curiosity, brevity, and emotional pull — and rewrite the weak ones for you.

Why hooks matter more than ever in 2026

Average completion time on short-form video has dropped to under 1.4 seconds before a viewer decides to swipe. That single first beat — visual + audio + opening line — decides whether your video gets shown to 200 people or 200,000. Algorithms across TikTok, Reels, and Shorts now treat the first-three-second retention curve as a primary signal: a strong hook is the cheapest distribution lever you have.

The good news is hooks are craft, not luck. The same patterns — specificity, opened information gaps, brevity, emotional triggers — show up in the top 1% of every niche. This tool grades you against those patterns and rewrites your hook so you can A/B test stronger versions before you film.

FAQ

What makes a strong short-form hook?

Specificity (numbers, named items), an opened curiosity gap, brevity (under 12 words), and an emotional trigger like surprise or status.

Does this work for TikTok, Reels, and Shorts?

Yes. The grading rubric is platform-aware — TikTok rewards a slightly punchier, faster pattern than YouTube Shorts.

Why does niche matter?

A great beauty hook is different from a great finance hook. The analyzer calibrates rewrites to your audience.

Is the tool free?

Yes, and no signup is required. There's a per-day limit; sign up for Postspace if you want unlimited use.
