How to use our free hook generator
Enter your topic in a few words, like “how I doubled my savings in a year”. The clearer the payoff, the stronger the hooks.
Pick a style: Instagram, TikTok, YouTube, LinkedIn or Any. TikTok hooks are fast pattern-breakers, YouTube hooks promise a clear payoff in the first five seconds, and LinkedIn hooks open with a story or an insight.
Press Generate hooks to get 10 one-line openers, each from a different angle: curiosity, a bold claim, a question or a pattern interrupt.
Tap any hook to copy it, or Copy all to keep the list. Use your pick as the first line of the caption or the first words you say on camera.
Why the first line matters for social media growth
People decide whether to stop scrolling in a moment, and all they've seen is your first line or the first second of your video. On most platforms a long caption is cut off behind a “more” link, so the opening is often the only part that shows. If it doesn't earn the tap, the rest of the post might as well not exist.
A strong hook makes a specific promise and then keeps it. “3 mistakes that make sourdough flat” beats “Some baking tips” because the reader knows exactly what they'll get. Skip fake clickbait: if the post doesn't deliver, people leave and remember. Write the post first, then try a few hooks and keep the most specific, honest one.
Frequently asked questions
What makes a good hook?
It's short, specific and honest. Name the payoff, open a question the post answers, or say something your audience doesn't expect — then deliver on it within the first few lines or seconds.
Can I use these hooks for videos?
Yes. Choose TikTok or YouTube for hooks written to be said out loud. Say the hook before any intro or logo, and put the same words on screen as text for people watching with the sound off.
Is the hook generator free?
Yes — free, with no sign-up and no cost. Because it uses AI, there's a fair-use limit per visitor: run it many times in a minute and it will ask you to take a short break.
