What is a hook generator?
A hook generator writes the opening line of an ad or short video for you. That line decides whether someone keeps watching or scrolls on. This one takes your product, category and main benefit and applies 10 well-known hook formulas (curiosity gap, fear of loss, social proof, transformation, contrarian, how-to, question, bold claim, number-led and "I tried it"), so you get 10 different angles instead of 10 versions of the same sentence.
Why It Matters
The hook carries more of an ad's result than any other line, because nobody reads the rest if the first second fails. Writing hooks one at a time is slow, and you tend to repeat the angle you already like. Generating ten across different formulas gives you variety worth testing, and the formula label shows which psychological trigger each one pulls. When you find a winner, the Hook Bank has more examples of the same pattern.
Frequently asked questions
Is this hook generator free?
Yes. You get 3 free generations with no sign-up. Join the free newsletter and generations are unlimited.
What makes a good video hook?
A good video hook works in the first one to three seconds. It names a specific problem, makes a concrete claim, or opens a question the viewer wants answered. On Reels and Shorts it usually works best as both the first spoken line and on-screen text, because many people watch with the sound off.
Can I use these hooks for Instagram Reels and YouTube Shorts?
Yes. The hooks are short enough to say in the first couple of seconds of a Reel or Short, and they also work as the first line of the primary text on a Meta feed ad.
How many hooks should I test?
Test hooks that differ in angle, not just wording. Three hooks from three different formulas tell you more than ten small rewrites of the same idea. Keep the rest of the ad identical so the hook is the only variable.
How do I know if my hook is any good?
Paste it into the free hook checker. It scores the hook, explains what holds it back and suggests rewrites.
