Hook Generator

AI TikTok hook generator, plus 30 hooks you can record today

A hook is the first sentence a viewer hears or reads. The generator in Go Viral writes several for any topic, across six hook types. The types and thirty finished examples are below, because a generator is more useful when you know what you are asking it for.

What a TikTok hook is

A TikTok hook is the opening line of a short video, spoken or written on screen, whose only job is to earn the next three seconds. It is not the topic and it is not the title. A topic tells the viewer what the video is about; a hook gives them a reason to find out. The six types that reliably do that are the curiosity gap, the contrarian claim, the result shown first, the point-of-view line, the numbered promise and the cold-open story. Every one of the thirty examples below belongs to one of the six, and the hook generator in Go Viral writes new lines in each type from a topic you type in.

Six hook types, thirty examples

Curiosity gap

Use it when: The payoff is surprising and you can hold it for ten seconds without cheating.

  1. Nobody told me this about renting in London until I had already signed.
  2. There is a setting on your iPhone that has been draining the battery since 2023.
  3. I asked a pastry chef why my croissants were flat. The answer was not the butter.
  4. The reason your plants die in September is not water.
  5. My landlord did one thing that made me stop looking for another flat.

Contrarian

Use it when: The common advice in your niche is wrong or incomplete, and you can show why in one clip.

  1. Stop stretching before you run.
  2. Meal prep is why you keep quitting your diet.
  3. You do not need a niche. You need a format.
  4. Posting every day is the worst advice on this app.
  5. The best time to post on TikTok is not a time.

Result first

Use it when: You have a number, a before-and-after or a finished thing to show in the first frame.

  1. This is 40 grams of protein for under two dollars.
  2. I went from 0 to 1,000 followers in 31 days and here is every video that did it.
  3. Three hundred words of this script were written by AI. Guess which.
  4. This room cost $180 to redo and I did it in a weekend.
  5. Here is the exact hook that got 2 million views, and the one before it that got 900.

Point of view

Use it when: The viewer will recognise themselves before you finish the sentence.

  1. POV: you said "one more episode" at 11:40.
  2. When the group chat goes quiet after you suggest a plan.
  3. Me explaining to my mum that posting on TikTok is a job.
  4. That moment the barista says your name wrong for the fourth time and you just accept it.
  5. When you finally open the tabs you have had open since March.

Numbered promise

Use it when: You have a list, and the list is short enough to finish before the viewer leaves.

  1. Three settings to change the day you get a new phone.
  2. Five hooks that stopped working in 2026, and what replaced them.
  3. Two ingredients, one pan, eleven minutes.
  4. Four things I would tell myself before my first client call.
  5. Six words to cut from every caption you write.

Cold-open story

Use it when: Something happened to you, it has a turn, and the turn arrives before second twenty.

  1. So the courier just handed me a box I did not order.
  2. At 2 a.m. my smoke alarm went off and it was not smoke.
  3. The email said "we need to talk" and had no other text in it.
  4. I got to the airport and my flight had been moved to yesterday.
  5. My daughter asked me what a cassette was and I did not have a good answer.

Change the nouns and the numbers and each line fits another niche. The shape is what carries the hook, and the shape is what the generator reproduces.

How the generator works in the app

  1. Type the topic in a sentence, the way you would tell a friend what the video is about.
  2. Choose the platform, so the length and phrasing match where it will be posted.
  3. Read the hooks that come back, across several of the six types.
  4. Record the two you can say naturally. A line that reads well and sounds stiff is not a hook.
  5. Import both takes and compare their hook scores. Post the one that scores higher.

The generator writes the line. It does not deliver it. The delivery has to happen inside the first two seconds of the recording, with the first word on the first frame, or the score will tell you what the test audience would have.

Five ways to waste the first three seconds

  • The greeting. “Hey guys” is two seconds spent on people who have not decided to stay.
  • The title card. Text that repeats the caption, on a frame where nothing moves.
  • The over-promise. A hook the video does not pay off gets the first three seconds and loses the next twenty, and the comments will say so.
  • The slow build. Context first, point at second eight. Put the point at second zero and the context after it.
  • The hook that never ends. A twenty-word opening is a paragraph. Cut it until it fits in one breath.

Hook writing questions

How do I write a hook for TikTok?

Start inside the action, make one specific promise, and deliver the first word before the first second is over. Pick one of the six types above, write five versions, record the two that read best out loud, and score both recordings with the hook score to choose.

How long should a TikTok hook be?

One spoken sentence of six to twelve words, delivered inside the first two to three seconds. On-screen text should be shorter still, six words or fewer, so it can be read at a glance while the sentence is being spoken.

Should the hook be text on screen or spoken?

Both, and they should not be identical. Speak the full line and put the sharpest three to six words of it on screen. A large share of viewers watch with sound off for the first second, and the text carries them to the moment the audio catches up.

Can I use the same hook on Reels and Shorts?

Usually yes. The hook types work across all three platforms. The one adjustment is that a Shorts title and description are read by search, so a hook with a searchable phrase in it does more work there than on TikTok.

Thirty hooks are here. The next thirty are one topic away.

Type the topic, pick a hook, record it, and score the take before it goes anywhere near the feed.
