How to Generate  Short Video Scripts  Using AI

Skip the theory. Here’s the workflow creators actually use.

The plan is simple: brief the model properly, generate your hooks first, cut ruthlessly to time, then add the one thing AI can’t: your voice. By the end of this page you’ll have a fill-in prompt template, a bank of hook formulas, a troubleshooting cheat sheet, and a finished 30-second script you can adapt to your niche.

Why the obsession with tight scripts? You get about three seconds before a viewer swipes. Most short-form videos now run under 40 seconds, with average length falling from ~76 seconds toward a projected ~39 (Siege Media). And clips that hold roughly 75% of viewers get pushed to about 3× more people (Socialinsider). Every word has to earn its place. That’s exactly the kind of constraint AI is great at helping you hit, as long as you stay in the director’s chair.

The whole thing in 10 minutes

If you only read one section, read this. Here’s the full loop: each step is broken down below with the exact prompt or template.

1. Brief the model like a director: paste the template, fill in your audience, goal, length, and angle.

2. Generate 5–10 hooks first using different formulas, then pick the two strongest.

3. Draft the body to a time target, then cut 30% and read it aloud.

4. De-slop it: swap every generic line for your own number, story, or take.

5. Format for sound-off: add on-screen text and caption cues.

6. Post, read the retention curve, and feed the lesson back into your next prompt.

The skeleton every winning short follows

You can’t prompt AI for a great script if you can’t describe one. Memorize this shape and put it in every brief: it’s the difference between a clip that holds and one that gets swiped.

0:00–0:03

Hook

One specific promise: a result, a reveal, a bold claim, or tension. No logos, no “Hey guys, welcome back.”

0:03–0:15

Promise / value

Tell them what they’re about to get so they commit. ~65% who survive the first 3 seconds reach 10; 45% of those reach 30 (RealMarketingSolutions).

↻ cut 2–4s

Body / escalation

Deliver the substance and keep attention moving: top Shorts average a cut every 2–4 seconds (OpusClip), with a pattern interrupt every 5–8.

payoff

Payoff

Deliver exactly what the hook promised. Breaking that promise tanks your watch time and your trust.

−0:05 → end

Call-to-action

One action only: follow, comment, save, or click. Keep it natural.

The workflow, step by step

Step 01

Paste this prompt and fill in the blanks

The gap between slop and gold is almost entirely the brief. “Write a TikTok about coffee” gives you nothing usable. Copy this template and replace the bracketed parts:

Copy-paste prompt

You are a short-form video scriptwriter.

Write a [30]-second [TikTok / Reel / Short] script for [specific audience].

Goal: [follows / saves / clicks / sales].

Structure: Hook (0–3s) → Value → Payoff → CTA.

My key insight (use this, don’t generalize): [your specific angle, stat, or story].

Tone: punchy, conversational, sound-off friendly.

Deliver the script with on-screen text cues, plus 5 alternative hooks using different structures.

That one block tells the model who it’s for, how long, where it’s going, what success looks like, your unique angle, the tone, and the format. The more specific your insight line, the less generic the result.

Generate your hooks first, in batches

Write the hook before anything else, every time. Ask for 5–10 variants, then A/B test the two strongest. This is where AI’s speed pays off most: producing ten credible openings by hand is a slog. Don’t over-promise, though. A hook that writes a cheque the video can’t cash causes a sharp drop a few seconds in. Hand the model these formulas so the options actually differ:

Problem + promise“If you’re still [doing X wrong], [do this instead].”
Shock stat“[N]% of [people] get [thing] wrong. Here’s the fix.”
Curiosity question“Why does [common thing] still [happen]?”
Bold claim“[Surprising claim]. And it’s not what you think.”
Mistake reveal“Stop [common habit]. Do this instead.”

Here’s what tightening a hook actually looks like:

Weak (skip)

“Hey everyone! Today I want to talk a bit about why grind size matters for your coffee.”

Greeting, slow build, no stakes. You’ve lost half the audience before the point.

Strong (use)

“You’re wasting half your expensive beans, and it’s not the beans’ fault.”

Starts at the payoff, specific claim, instant curiosity gap. No throat-clearing.

Draft to a time target, then cut 30%

Give the AI the runtime out loud (“target 25 seconds spoken”) and let it draft the body. Then apply the rule every creator learns the hard way: your first draft is too long, so cut it by about 30%. You can make the model do it (“remove every word that doesn’t serve the core message”), but read it aloud and time yourself. A tight 20-second clip beats a flabby 45.

De-slop it: this is the step that matters most

This is what separates content that gets watched from content that gets ignored, and it’s non-negotiable. Go line by line and replace generic claims with your specifics: real numbers from your analytics, a personal story, a contrarian take, or the exact mistake you made.

AI slop

“This simple tip will completely transform your results.”

Your voice

“I tested this on 30 of my own uploads. Average view duration jumped from 41% to 68%.”

The AI gives you the scaffold. The lived experience (the part no model has) is what you bring.

Format for sound-off

Most short-form video is watched on mute, so on-screen text isn’t optional. Ask the model to mark the hook’s on-screen caption (4–7 high-contrast words) and flag where text should pop. Repurposing one idea across platforms? Ask for platform versions: TikTok and Reels reward a looser, trend-aware tone; Shorts skews a touch more informational.

Post, read the curve, feed it back

This is a loop, not a one-shot. After posting, open your analytics. A sharp drop at 0:03 means the hook failed; a cliff in the middle means pacing. Your retention graph shows you exactly where you bored people, so listen to it, then put the lesson in your next prompt: “my last hook lost 40% at 3 seconds; make this opening more concrete and faster.” Your scripts improve because your briefs improve.

Watch it work: a 30-second script, start to finish

Here’s the coffee-roaster example run all the way through: the filled brief produced this, then a quick de-slop pass made it real. Steal the shape, swap in your niche.

Finished 30-second script

0:00–0:03

Hook

“You’re wasting nearly half your expensive beans, and it’s not the beans.”

TEXT:  You’re wasting your beans.

0:03–0:12

Value

“Most home grinders are uneven. The big chunks under-extract, the dust over-extracts, so you taste sour and bitter in the same cup.”

0:12–0:24

Payoff

“Ten-second fix: lock one consistent grind for your brewer, then sift out the dust with a cheap mesh. Same beans: suddenly sweet, clean, balanced.”

TEXT:  Same beans. Better cup.

0:24–0:30

CTA

“Follow and I’ll drop my grind-size chart for every brewer.”

TEXT:  Follow for the chart →

When AI gets it wrong (and the one-line fix)

AI will get plenty wrong. That’s expected. Here’s the honest list of its weak spots and the exact follow-up prompt that fixes each. Keep this handy; it’s faster than starting over.

It sounds generic, could’ve been written for anyone.Rewrite using this exact story or number: [yours]. Cut every sentence that doesn’t add a specific detail.
The hook is soft or slow to start.Make the first line a bold claim or a number. Delete any greeting, intro, or setup before it.
It’s too long and rambly.Cut to 30 seconds spoken aloud. Remove filler words and combine sentences. Keep only the single core message.
It invented a statistic or “fact.”Don’t invent numbers or claims. Use only the facts I gave you, and flag anything you’re unsure about.
All five hooks feel the same.Give me 5 hooks using 5 different structures: question, bold claim, stat, mistake reveal, and short story.

That last point is the strategic one: AI writing is now a commodity, so the edge has shifted from using AI to using it well. Treat the model as a co-writer, not a ghostwriter, and you stay on the right side of the “AI slop” most viewers can now smell instantly. (It’s also what Google’s guidance rewards: it doesn’t penalize AI help, but it does penalize low-value, mass-produced pages.)

Which tools to use

Two categories, and most creators use both. For the writing itself, reach for a general-purpose model: ChatGPT, Claude, or Gemini. They take rich briefs and handle ideation, drafting, variations, and cutting. (In a 2026 Siege Media survey, ChatGPT led at 80% usage, Claude next at 55%.)

Then dedicated tools add convenience: purpose-built script generators and platforms like Jasper offer hook-tuned templates; OpusClip turns long videos into captioned Shorts; and text-to-video tools like Synthesia, Runway, and Sora generate footage from your script. A practical stack: write and refine in a general model, then move to a dedicated tool for captions, clipping, or generation. Choose by your real workflow, not the loudest pitch.

Your quick-start checklist

Paste the prompt template and fill in audience, goal, length, and your angle.

Ask for 5–10 hooks in different formulas; A/B test the two best.

Draft to a time target, then cut 30% and read it aloud.

De-slop every line with your own data, story, or take.

Add on-screen text (4–7 words) for sound-off viewing.

Read your retention curve and feed the lesson into the next prompt.

Never publish a stat the AI gave you without checking it.

AI won’t make you a great creator on its own. What it does is kill the blank page and scale your ideas across every platform. Instantly. Bring the strategy, the specifics, and the voice yourself, and you get the best of both: machine speed with a human spark.
