15 Hook Formulas That Stop the Scroll on Reels and Shorts

The short answer: a hook is the first line of spoken audio and the first line of on-screen text, and it has about 1.5 seconds to give a stranger a reason to stay. The formulas below all do one of three things — promise specific value, open a loop, or contradict something the viewer believes. Everything else in a short clip is downstream of that line.

What a hook is actually doing

Short-form feeds are an endless supply of alternatives. The viewer is not deciding whether your clip is good; they are deciding, pre-consciously, whether to keep scrolling. So the hook has one job: make the next second feel more interesting than the unknown next video.

There are only three mechanisms that reliably do this:

• Specific promise — name the exact thing they will know by the end.
• Open loop — start a sentence that demands completion.
• Pattern break — assert something that contradicts the viewer's model of the world.

Every formula below is one of those three wearing different clothes.

15 hook formulas that work

Specific promise

1. The number promise. "Three things I would do differently if I started again in 2026." Numbers imply the clip is finite and structured, which lowers the cost of committing.
2. The timeframe promise. "How to go from zero to your first paying customer in 30 days." Time bounds make an outcome feel achievable.
3. The shortcut. "The fastest way to X without Y." The "without" clause is doing most of the work — it names the thing they dread.
4. The named tool or method. "This is the exact framework we used to..." Specificity reads as real experience.
5. The audience call-out. "If you run a podcast and you are not doing this, you are leaving reach on the table." Explicit targeting increases relevance for the right viewer and filters the wrong one.

Open loop

6. The unfinished story. "I lost the biggest client I ever had, and it was one email." Narrative tension is the oldest hook there is.
7. The withheld answer. "Everyone asks me which tool I use. It is not the one you think." Naming the answer later is the whole trick.
8. The question the viewer was already asking. "Why do your Reels get 200 views when your last one got 40,000?"
9. The mid-sentence entry. Start the clip mid-thought, so it feels like walking in on something. This is the one clipping tools find for you, because the transcript makes it visible.
10. The stakes statement. "This mistake cost us six months." Consequence implies a lesson is coming.

Pattern break

11. The contradiction. "Posting daily is the worst advice in this industry." Only use it if you can defend it in the next 20 seconds.
12. The confession. "I have been doing this wrong for two years." Admitting fault buys enormous goodwill and is rare enough to register.
13. The unexpected number. "We spent nothing on ads and it still worked." Counter-intuitive specifics are sticky.
14. The permission slip. "You are allowed to stop doing this." Relief is an underrated emotion in a feed full of demands.
15. The comparison. "Editing a clip by hand takes 40 minutes. Doing it this way takes four." Concrete before-and-after, no adjectives required.

Writing the on-screen hook separately

The spoken hook and the text hook are different assets and should be written separately. The text is read first — it is on screen before the audio has said two words. Rules that hold up:

• Six words or fewer. It is a headline, not a sentence.
• No brand name in the first line. Nobody stops scrolling for a logo.
• Front-load the interesting noun. "40 minutes wasted" beats "Here is how I saved 40 minutes".
• Do not duplicate the spoken line word for word — let them stack instead of echo.

Where to find hooks in footage you already have

The hooks in this list are not written from scratch most of the time — they are found. In a recorded conversation, the good ones are already there, usually in the fifteen seconds after a guest is challenged or immediately after someone says "honestly" or "the thing nobody tells you".

This is exactly what a transcript-scoring pass is good at. When AI Clip Cutter analyses a video, one of the four axes it scores each candidate segment on is hook potential, and every selected clip comes back with three alternative hook lines drawn from what was actually said. You are choosing between real options rather than staring at a blank field.

Testing hooks without guessing

1. Post the same clip twice with different hooks, a week apart, on the same account. Retention at three seconds is your read-out.
2. Watch the first-three-second drop-off, not total views. Views are downstream; the drop-off is the hook.
3. Keep a running list of your top five. Hooks that work for your audience work repeatedly. Formula fatigue takes months, not weeks.

Frequently asked questions

How long should a hook be?

Under three seconds spoken, under six words on screen. If the claim needs a preamble, the claim is in the wrong place — move the clip start.

Do clickbait hooks hurt you?

A hook that oversells gets the view and loses the retention, and retention is what the ranking actually responds to. Promise something the clip genuinely delivers in the next 30 seconds.

Should the hook be the loudest moment of the clip?

Not necessarily loud — but it should be the most consequential moment. Quiet certainty outperforms shouting in almost every category except entertainment.

Can AI write my hooks?

It can shortlist them. The lines that perform are the ones you actually said, surfaced and tightened — which is why hook suggestions worth using are drawn from your transcript rather than invented.

Try it on your own footage

Run one episode through AI Clip Cutter — 10 free credits, no card — and look at the hook lines it pulls out of what you already said. Then rewrite the best one using a formula above. That is the whole loop. If you want the full pipeline first, start with turning long videos into shorts.
