Hook Analyzer
Paste your video hook. Get an instant score across 4 axes — curiosity, specificity, stakes, pacing — plus 3 AI rewrites. Find your weakest spot and fix it.
What separates a strong hook from one that loses viewers
The first 5 seconds of your video determine whether someone watches or scrolls past. Most creators nail the topic but fumble the execution — the hook is too vague, too slow, or makes no promise worth keeping.
"Hey everyone, today I want to talk about something important..."
No hook. No stakes. No curiosity. The viewer has zero reason to keep watching.
"I deleted all 200k followers and started over — 90 days later the data looked nothing like I expected."
Specific. Bold. Stakes. Creates a curiosity gap. Viewers need to know the outcome.
"In this video, I'll show you how to grow on TikTok."
Vague. Generic. Doesn't signal anything the viewer doesn't already know. Zero specificity.
"I posted every day for 30 days using this one hook format — here are the exact results."
Time-bound. Specific action. Implied data. High stakes. Viewers want to see the results.
Why the first 5 seconds of your video are everything
Every major platform — YouTube, TikTok, Instagram — rewards content that holds attention. The algorithm measures watch time, retention, and re-watches, then amplifies videos that perform well early. A weak hook kills your reach before the platform ever has a chance to surface your video to new viewers.
The Flair Hook Analyzer is built for creators who know the topic but want to know if the execution is working. Paste your opener and get a score across four axes: curiosity (does it create a knowledge gap?), specificity (does it use concrete numbers, names, or outcomes?), stakes (does it make the viewer feel they'll miss something important?), and pacing (is it punchy, or does it waste words?). The AI identifies your weakest axis and gives you three targeted rewrites to fix it.
What the four axes mean
Curiosity is the most powerful hook lever. A curious hook makes viewers feel they need to know what happens next — even if they can't articulate why. Patterns ("I tested X on 100 videos"), anomalies ("Here's why X doesn't work the way you think"), and open loops ("The number I found shocked me") all score high on curiosity.
Specificity is the antidote to vagueness. "I grew my channel" scores low. "I went from 1k to 73k followers in 8 months using one strategy" scores high. Specific numbers, timeframes, and named outcomes signal credibility and make your hook believable.
Stakes make the viewer feel like they'll miss something important if they scroll. A high-stakes hook says "what I'm about to show you matters" — not just "this exists." The difference between "Here's a productivity tip" and "Here's the mistake that's costing you 3 hours a day" is entirely stakes.
Pacing is about efficiency. Every word in your hook should earn its place. No throat-clearing ("So, um, today I wanted to talk about..."), no qualifiers ("I think maybe..."), no setup that could be cut. The first line should hit hard and fast.

Frequently asked questions
How does the free hook analyzer work?

What does "weakest axis" mean?
The AI identifies which of the four axes — curiosity, specificity, stakes, or pacing — scored lowest on your hook and explains exactly what's missing. Most hooks are weak on specificity (too vague) or stakes (no FOMO signal). The rewrites are targeted to fix that specific axis.
Does it work for YouTube and TikTok hooks?
Yes — the hook analyzer works for any short-form video platform. The scoring criteria are universal for video openers. TikTok hooks tend to need faster pacing and higher curiosity to stop the scroll; YouTube hooks can afford slightly more setup before the payoff.
