A short-form video lives or dies in its first three seconds. This free AI video script generator writes a ready-to-record script for YouTube Shorts, TikTok, and Instagram Reels from a single topic — structured the way videos that actually retain viewers are structured: a hook that stops the scroll, a tight middle that delivers one clear idea, and a close that earns the next action.
Type a topic, pick a length (30, 60, or 90 seconds), and you get a spoken-word script plus quick recommendations. No login, no credit card. Below the tool is everything you need to turn that script into a video people watch to the end.
How to use the script generator
- Enter a specific topic — "3 budgeting mistakes in your 20s" beats "money tips". Specific topics produce sharper hooks.
- Choose your target length. 30s suits a single punchy idea; 60–90s fits a list or a mini-story.
- Generate, then read it out loud. If a line is hard to say, cut it — short-form scripts are written for the ear, not the page.
- Tweak the hook first. It is the only line guaranteed to be seen, so it deserves most of your editing time.
Anatomy of a short-form script that retains
Every high-retention Short follows the same three-part shape. The generator writes to this shape so your edits stay structural, not from scratch.
- Hook (0–3s): state the payoff or the tension immediately. No "hey guys", no slow intro. The viewer must know in one breath why to keep watching.
- Body (the middle): one idea, delivered in short sentences with concrete specifics. Each line should either advance the point or raise a small open loop that the next line closes.
- Close (last 2–4s): a single call to action — follow for part 2, comment a word, or try the thing. One ask, not three.
Hook formulas that work
When you rewrite the opening line, steal one of these proven patterns:
- The contrarian: "Everything you've been told about X is wrong."
- The stakes: "This one mistake cost me $4,000."
- The list promise: "3 tools that feel illegal to know."
- The curiosity gap: "Nobody talks about what happens after you go viral."
- The direct callout: "If you make videos and get zero views, watch this."
How long should the script be?
People speak at roughly 130–160 words per minute in energetic short-form delivery. Use that to size your script before you record:
- 30 seconds ≈ 70–80 words
- 60 seconds ≈ 140–160 words
- 90 seconds ≈ 210–240 words
- Always write slightly short. Pauses, b-roll, and on-screen text eat real time, and an overlong script forces rushed delivery.
Mistakes that kill retention
- A slow intro. If the first line is throat-clearing, the video is already losing viewers.
- Too many ideas. One Short = one idea. Save the rest for the next video (and the algorithm rewards consistency anyway).
- Writing for readers, not listeners. Long clauses and jargon do not survive being spoken at speed.
- No reason to stay. Every line should pull toward the next; the moment it flattens, viewers swipe.
- A weak or missing CTA. The last frame is prime real estate — use it for exactly one ask.
From script to finished video
A script is step one. To publish, you still need a voiceover, visuals that match each line, captions, and a vertical render. You can do that manually across several tools — or paste the script straight into AutoShort.org and get an AI voiceover, on-prompt visuals, word-by-word captions, and a ready-to-post video in about a minute.
AutoShort charges per video (about $0.80–$2) instead of a monthly subscription, and starts with 100 free credits — so you can turn this script into a real video without committing to a plan.
Frequently asked questions
Is this AI video script generator free?
Yes. The script generator is 100% free with no login or credit card required. Generate as many short-form scripts as you need.
How many words is a 60-second video script?
About 140–160 words, based on a natural short-form speaking pace of 130–160 words per minute. Write slightly short to leave room for pauses, b-roll, and on-screen text.
Can I use these scripts for TikTok and Instagram Reels?
Yes. The hook-body-close structure works across YouTube Shorts, TikTok, and Instagram Reels — they all reward strong openings and high watch-time.
How do I make the script go viral?
Spend most of your effort on the first line (the hook), keep to one idea, write short spoken sentences, and end with a single clear call to action. Then post consistently — volume plus a strong hook beats a single perfect video.
How do I turn the script into an actual video?
Paste it into AutoShort.org to auto-generate the voiceover, visuals, and captions and render a vertical video, or record it yourself. AutoShort is pay-per-video with 100 free credits to start.
