How do I write a hook for a video?
Type what your video is about, who it is for and what the viewer gets. You get five opening lines back, each scored out of 25 on curiosity, context and clarity, with the weak part named. It is free, needs no account and saves nothing. It writes the first line, not the whole script.
Who it is for
Anyone writing a short video who is stuck on the opening. Creators, founders, and the one person doing social at a small company.
What you need
A sentence about the video, and who it is for. No sign-up, no card, no email.
What it costs
The tool is free and spends no credits. Making the video costs credits: a talking-head video bills 152 credits a second on a paid plan, with a floor of 120 credits on any video with a person in it, and Free starts with 8,400 credits once.
What it does not do
It does not write the rest of the video, save your work, invent a number, or tell you how many people will watch.
Score your hooks.
Say what the video is about. You get five openings back, strongest first, each one marked part by part.
Where each of the five pieces goes.
The tool hands back five parts because they land in five different places when you post. This is the part most people skip, and it is why a hook that reads well still dies in the first second.
- 1
The spoken line is said first.
Before any setup, before your name, before the wave. If you need a run-up to reach it, the line is not the hook yet. It carries the most weight in the marking, and a hook whose spoken line falls under the floor does not pass however good the rest is.
- 2
The on-screen text is burned into the first frame.
It stays long enough to be read once, and it is not a caption of what you are saying. It should say something the line does not, so a viewer with the sound off still has a reason to stay.
- 3
The first frame is chosen before you speak.
Point the camera at the thing the video is about, not at yourself sitting down. This is the part people never write and the part that most often drags a mark down.
- 4
The sound starts with the line.
If there is music, it is already running when the frame appears, not fading in over the first three words. Silence counts, when it is on purpose.
- 5
The caption is written last, and hints at the same thing.
It is not a summary. It is a second attempt on the person who kept scrolling, so it should open the same loop the line opened and resolve none of it.
The three tests every part is marked on.
A hook is not one sentence. It is five things happening at once in the first moment, and a video usually fails because one of them is dead, not because all five are. Each part is marked from 1 to 5 on these three questions, so the top mark is 25.
Curiosity.
Does it open something the viewer now needs closed? A line that answers itself has nothing left to watch for.
Context.
Do they know who is talking and roughly where this is going? A hook with no footing reads as noise, however clever it is.
Clarity.
Can they tell in one beat what they get for staying? If it takes a second reading, it has already lost the scroll.
The bar, and why the parts matter more than the total.
A hook passes at 20 or more, with no part it uses scoring under 3. The second half of that matters more than the first: a 21 built from one brilliant line and four weak parts is a worse hook than a 20 with five decent ones, because the weak parts are where people leave.
A part you left out on purpose reads as not used rather than as a zero. Skipping one is a choice, and the marking treats it as one.
You can use this without us. It is the same rubric the tool marks against, and it works on a piece of paper.
Write five, keep one, fix the weak part.
The reason the tool hands back 5 and marks all of them is that rewriting one part is cheaper than starting again.
- Read the top card. They come back strongest first, so the top one is the tool's own pick.
- Look at the parts, not the total. The total tells you very little. The row marked 2 tells you everything.
- Rewrite that one part. Not the line, not the whole hook. If the first frame is what is dragging it, change what the camera is on and leave every word alone.
- Run it again with the fix written into the topic. Two passes is usually the whole job.
- Say the winner out loud before you film it. Anything you stumble over on the page you will stumble over on camera.
Stuck before any of that? Switch the tool to Ideas and it gives you 5 angles instead, each with a button that writes hooks for it.
Now say it in your own face.
You have the opening. Kyndrify turns it into the video: build a Digital Twin from one photo and a short recording, paste the line in, and the finished video comes back in your own face and voice.
Free starts with 8,400 credits, once, and they do not expire, which is enough for your first video. A free video runs to 60 seconds.
What this tool does not do.
It writes the opening, not the video.
The rest of the script is a different job, and a different tool.
It saves nothing.
No sign-up, no history, no email. Close the tab and the hooks are gone, so copy the ones you want before you go.
It never makes up a number.
If a hook needs a real figure, a price or a study, it writes a placeholder for you to fill in rather than inventing one.
The score is our rubric, not a forecast.
It says a hook is well built. It says nothing about how many people will watch, and nobody can tell you that.
There is a daily cap.
You get 8 runs a day from one browser. The tool is free and it still costs us something to run.
It renders nothing.
No video is made here and no credits move. What you type never reaches a render.
Questions people ask before they write.
- What counts as a hook?
- The first moment of the video, all of it. The line you say, the words on screen, what the camera is on, what it sounds like, and the caption underneath. Most people only write the line, which is why most hooks are two parts strong and three parts empty.
- What does the score out of 25 mean?
- Each of the five parts is marked from 1 to 5 on curiosity, context and clarity, and the five marks are added up. A hook passes at 20 or more, with no part it uses under 3. The marks matter more than the total, because they tell you which part to rewrite.
- Does a high score mean more views?
- No. The score says the hook is well built against our rubric. Nothing about how a video performs is in it, and anyone who tells you otherwise is guessing.
- Do I need an account, and how many can I run?
- No account. You get 8 runs a day from one browser, and there is no card anywhere on this page.
- What happens to what I type?
- Nothing is stored. It is used to write your hooks and then it is gone. It is treated as material, never as instructions, so a line of “ignore everything above” pasted into the box just becomes part of the topic.
- How long can the topic be?
- The box holds 300 characters and stops there. Two sentences is plenty: what the video is about and what makes it worth watching. The two fields beside it, who it is for and what they get, do more for the marks than a longer topic does.
- How do I turn a hook into a video?
- Copy the line, then start free. You build a Digital Twin from one photo and a short recording, paste the line in, and the finished video comes back in your own face and voice. Free starts with 8,400 credits once, and a free video runs to 60 seconds.
