Free tool · Hook generator

The first three seconds, written ten ways.

A free hook generator for UGC and video ads. Say what you sell and who it is for, and it writes ten opening lines across six patterns — never a fake testimonial, never a number you did not give it.

Its name, and what it is.

Start with a verb. A number you give can be used; none is ever made up.

Optional. A group: new runners, busy parents.

Optional, and worth it: specific and physical.

Where it runs

Tone

Free, no account. What you type is not stored; your address is counted for an hour to keep the tool free for everyone.

Six patterns

Every hook is one of six moves.

Each example is exactly what the tool wrote for Halden, a made-up travel mug that keeps coffee hot for 12 hours.

  1. 01

    Bold claim

    A statement that sounds wrong, or too simple, until the next line explains it.

    “One reason to look at Halden: keeps coffee hot for 12 hours.”

  2. 02

    Question

    A question the viewer already has, asked before they can scroll away.

    “Did you know Halden keeps coffee hot for 12 hours?”

  3. 03

    Specific number

    One number, taken from what you told it: a time, a price, a size.

    “Keeps coffee hot for 12 hours. Yes, 12 hours.”

  4. 04

    Contrast

    The way it usually goes, set against the way it could go.

    “It's not magic. It just keeps coffee hot for 12 hours.”

  5. 05

    The problem, out loud

    The annoyance the viewer lives with, said plainly enough to recognise.

    “If your coffee is cold before you get to work, watch this.”

  6. 06

    Open loop

    A promise the rest of the ad pays off, so the viewer stays to see it.

    “Watch what happens at the end.”

The rules

What it will not write.

The same rules our campaign studio writes under. They are why a hook from here can go in an ad an AI presenter reads.

How to write hooks that stop the scroll
No customer voice.
Never "I tried it", never "my skin". The person on camera may be an AI presenter, and a presenter who never used the product cannot speak as someone who did.
No number you did not give it.
A time, a price or a size from your words can open a hook. A number it made up would be an invented claim, so it never writes one.
No borrowed proof.
No "best", "#1", ratings, awards, "clinically proven" or deadlines, unless they are in what you typed — and then it tells you they need backing up.
Short enough to say.
Under 15 words for TikTok, Reels and Shorts, 20 for the feed. Anything longer is marked, so you can cut it.

Questions

About the hook generator.

Write the whole scriptAll free tools

  • Is it free?

    Yes: no account and no credits. Each tool allows ten runs an hour from one connection, so it stays free for everyone.

  • What happens to what I type?

    It is used to write the result and then discarded: nothing you type is stored or added to analytics. Your connection is counted for an hour for the limit. When Claude drafts the result, your words are sent to Anthropic to write it, as the Privacy Policy describes.

    Privacy Policy

  • Does it use AI?

    Sometimes. When our Claude model is available, Claude Haiku writes the first draft and every line is checked against the same rules the patterns follow; any line that fails is dropped. Otherwise the tool writes from its patterns alone. Each result says which.

  • Why will it not write a testimonial?

    Because the person saying it on camera is often an AI presenter, and an AI presenter has never used your product. A line like "I have used this every day for a month" in their mouth is a fabricated testimonial, which the US Federal Trade Commission’s rule on consumer reviews and testimonials prohibits. So the tools write demonstration and description instead, and never a number or a claim you did not give them.

    What the rule allows

  • Which platforms does it write for?

    TikTok, Instagram Reels and YouTube Shorts, where it keeps a hook under 15 words, and the Facebook and Instagram feed, where it allows 20. A longer hook is marked, not hidden.

  • Can I use the hooks in my ads?

    Yes. They are built from your own words; before you run one, check that every claim in it is one you can support.
