How to use AI to generate a week of short-form video…

You've got a blog post sitting there that took you two hours to write, and your Instagram Reels feed is basically tumbleweeds. Meanwhile, you know you should be doing short-form video, but every time you sit down to film, you stare at the camera and go completely blank.

This post shows you how to use AI to turn a blog post into video scripts — a full week of ready-to-film content pulled straight out of that blog post, or even a dusty service page on your website — in under an hour. You already did the hard part when you wrote the content; now you're just giving it a second life.

What you need before you start

ChatGPT{:target="_blank"} — an AI assistant made by OpenAI that can read your content and rewrite it in almost any format you ask for. The free version (GPT-4o mini) is enough to get through this whole workflow. If you want a little more nuance and flexibility, Claude{:target="_blank"} (free tier, Sonnet 3.5) is an excellent alternative.

Time required: About 45–60 minutes the first time through. Once you've done it once, you'll cut that in half.

Skill level: If you can copy, paste, and type a sentence, you can do this. There's no software to install, no account to connect, and nothing to break.

How to pick the right blog content to convert into AI video scripts

Not every piece of content is equally ready for video. Here's how to spot the good ones fast.

Open your website and look at your blog or services pages. You're scanning for content that answers a question, solves a problem, or explains something your clients always ask about.
Prioritize posts with a list, a process, or a strong opinion — "5 mistakes homeowners make before calling a plumber" converts into video much more cleanly than "Welcome to our blog." Common questions you've answered in writing are gold.
Grab the URL of the page you want to use, or open the post and select all the text (Ctrl+A or Cmd+A), then copy it. Either works. If you're using ChatGPT or Claude's free tier without browsing enabled, pasting the text directly is more reliable.
Pick one piece of content to start. A 500–800 word blog post has enough material in it for 3–5 separate scripts. That's a full week of content from a single asset. Don't overthink the selection — the one that gets the most client questions is usually the right call.

Service pages are especially worth revisiting here. They rarely get updated, they barely get shared, but they describe exactly what you do and why someone should hire you. A plumber's "drain cleaning" page, a salon's "balayage services" page, a coach's "90-day program" page — all of them have video scripts hiding inside.

How to extract the right raw material from your content

Before you ask AI to write scripts, you want it to pull out the bones of your content first. This two-step approach — called prompt chaining — produces scripts that are actually usable rather than generic. Think of it like asking someone to read a book before they summarise it, rather than making up a summary from the cover.

Step 1: Extract the key insights

Paste your blog content into ChatGPT or Claude. Then use this prompt:

Read the content below and extract exactly 5 distinct, specific insights, tips, or points that would be genuinely useful to [describe your audience — e.g., "homeowners dealing with plumbing problems" or "small salon owners"]. For each one, write a single sentence that captures the core idea as clearly and concisely as possible. Number them 1–5.

[Paste your blog post or service page text here]

You'll get back five clean, focused points. These are your five video topics for the week. Read through them and make sure they actually sound like you — tweak any that feel off.

Step 2: Turn each point into a full script

Once you have your five points, ask AI to build each one into a script. This prompt gets you a properly structured short-form video script every time:

Write a short-form video script for Instagram Reels (or TikTok / YouTube Shorts) based on this single idea: [paste one point from your list].

Use this structure:

Hook (first 1–3 seconds): One punchy sentence that makes someone stop scrolling. Use a "POV:", "Nobody talks about...", or "Here's why [common belief] is wrong..." format if it fits naturally.

Body (15–45 seconds): Explain the idea in plain, conversational language. Write it the way someone would actually say it out loud, not how they'd write it in an email.

CTA (last 3–5 seconds): One simple, low-pressure call to action.

Keep the total script between 75 and 150 words. My audience is [describe your audience]. My tone is [warm/direct/educational/casual — pick one].

Run this prompt five times — once for each of your five points — and you'll have a week of scripts ready to review.

How to adapt AI short-form video scripts for different platforms

The structure stays the same across Instagram Reels, TikTok, and YouTube Shorts. What changes is the tone and the hook style.

For Instagram Reels, the audience tends to respond to slightly more polished, value-forward hooks. "Three things your [professional] won't tell you" does well here.
For TikTok, lean more conversational and raw. First-person, present tense, a little imperfect. "I spent six years doing this wrong and here's what I finally figured out" feels native to the platform in a way that "tips and tricks" content doesn't.
For YouTube Shorts, the hook can be a direct question. "Are you actually saving money going DIY on this?" gives the algorithm something to latch onto and gives the viewer a reason to stay.

To adapt a script you've already written, just tell AI: "Rewrite this script for TikTok. Make the hook more conversational and personal, like I'm talking to a friend." That's it. Thirty-second job.

When something goes wrong

The script sounds stiff and formal, like a brochure. This happens when AI defaults to "professional writing mode" because you didn't tell it otherwise. Go back and add "Write this the way someone would actually say it out loud, including natural pauses, contractions, and informal language" to your prompt. That phrase alone fixes most of it.

All five scripts feel like they're saying the same thing. You probably gave AI very similar points to work with. Go back to Step 1 and ask it to "make each insight as distinct from the others as possible — no overlap in topic or angle." It'll redistribute the content more thoughtfully.

The hook feels too generic. Phrases like "In today's world..." or "Have you ever wondered..." are AI's default when it doesn't have enough context. Give it more: your location, your specific type of client, a common misconception your clients have. The more specific the brief, the more specific the output.

What to do next

Save your five scripts in a simple document — a Google Doc works fine — and batch-film them in one session. You don't need to post them all at once. One a day runs a full week.

FAQ

Can I use AI to turn a blog post into video scripts without paying for ChatGPT?

Yes. The free tier of ChatGPT{:target="_blank"} (GPT-4o mini) handles this workflow without a subscription. Claude's{:target="_blank"} free tier works too. You might hit usage limits if you're running a lot of prompts in one session — if that happens, just wait an hour or switch between the two.

What if my blog posts are pretty short — like under 400 words?

You might only get 2–3 strong scripts out of a shorter post, which is still a solid start. You can also combine two related short posts and feed them in together — just tell AI "here are two related posts, treat them as one piece of content."

Can I use a service page instead of a blog post to generate video scripts?

Absolutely — and honestly, service pages often make better video content because they already describe what you do and who it's for. A "what's included" section, an FAQ on the page, or a "who this is right for" paragraph can each become its own script.

Won't the scripts sound like AI wrote them?

They will if you post them unedited. Read each one out loud before you film. Wherever you stumble or it sounds weird, rewrite that sentence in your own words. Two minutes of editing per script makes a noticeable difference.

How long should each video actually be?

For Reels and TikTok, 30–60 seconds hits the sweet spot for retention right now. The 75–150 word scripts this workflow produces land right in that range when spoken at a natural pace — roughly 130–150 words per minute for most people.
