Draft in, five first lines out.
What a hook is, and why it carries the post
A hook is the opening line of a post or video, the part someone sees before deciding to keep reading or scroll on. On LinkedIn only the opening lines show before “see more”. On Twitter the first line sits at the top of a 280-character post. In a short video it is the first thing you say. Everything after the hook only gets read if the hook works, which is why a good post with a slow opening performs like a weak one.
Five hook angles, and when to use each
Each run returns one hook per angle, so you can see which framing of your idea pulls hardest:
Contrarian. Pushes against what people assume. “Most onboarding emails should not exist.” Best when you genuinely disagree.
Curiosity. Opens a gap the reader wants closed. “We deleted our most-visited page. Here is what happened next.” Best for stories with a twist.
Specific result. Leads with a concrete outcome. It only uses numbers you give it, never invented ones.
Story open. Drops the reader into a moment. “At 2am the night before launch, our payment page went blank.”
Bold claim. A strong statement with a reason behind it. Best when you can back it up in the next line.
Hooks by platform
Twitter: the hook is often the whole post, so it has to stand alone inside 280 characters. For full tweets, try the AI tweet generator.
LinkedIn: the hook has to earn the “see more” tap. For LinkedIn-only openers, use the LinkedIn hook generator.
Instagram: the first line of the caption sits under the image, so it should add to the picture, not describe it.
Short video: one spoken sentence you can say in a single breath, before anyone swipes.
What an AI hook generator should refuse to write
The fastest way to lose trust is a hook the post cannot pay off. This hook generator is told to leave out:
Fake numbers. No “I made $10k in 30 days” unless you gave it that number.
Bait. No “You won't believe” and no “Nobody is talking about this”.
Promises the post cannot keep. If the hook says “the one trick”, the post had better contain one trick.
To see which openings travel in the wild, break down any tweet with the viral tweet analyzer.
A good hook needs a post that keeps the promise
The hook gets the tap; the rest of the post earns the follow.
