Most short-form video fails in the first three seconds, and almost always for the same reason: the script starts with throat-clearing. “Hey guys, in today’s video…” is three seconds spent saying nothing, and three seconds is the whole budget.
This generator returns a voiceover-ready script — spoken narration plus a matching scene description for each line — so you can hear the pacing and see the visuals at the same time.
Open on the payoff, not the preamble
Start with the most interesting sentence you have. Not the introduction to it — the sentence itself. If your video explains why a format works, open with the claim, then justify it. The explanation earns attention only after the claim has bought it.
A reliable trick: write the script, then delete the first two sentences. They are almost always warm-up.
Write for the ear, not the page
Spoken narration follows different rules from prose. Sentences run shorter. Subordinate clauses get cut. Numbers are spoken as words. The reliable test is to read a draft aloud at normal speed — anywhere you stumble is a line a voice model will stumble on too.
Roughly 150 words per minute is a natural pace, so a 45-second video is about 110 words. Writing 200 and hoping to speed up produces narration that sounds panicked.
One idea per scene
Each line of narration should map to one thing the viewer sees. When a single shot has to carry three sentences, attention drifts; when the visual changes on every idea, the video feels faster than it is. That is why the script comes with scene descriptions attached rather than as a wall of narration.
End with one instruction
A closing line that asks for a follow, a like, a comment and a subscribe gets none of them. Pick the single action that matters for this video and ask for it plainly. Better still, make the last line a reason to watch the next one — retention across videos beats any call to action inside one.
Frequently asked questions
Is this AI script generator free?
Yes — no signup, no email, no credits. Generate as many scripts as you want.
How long should a short-form video script be?
About 150 spoken words per minute. That is roughly 75 words for 30 seconds, 110 for 45 seconds and 150 for a minute. Write to the duration rather than trimming afterwards.
Can I use the script commercially?
Yes. What you generate is yours to use, edit and monetise, including in client work.
Does it write the scene descriptions too?
Yes. Each narration line comes with a matching visual direction, so the script can be handed straight to an editor or fed into a video generator.
Can I turn the script into an actual video?
Yes — that is what Shortlify does. Paste the script into the editor and it generates the scenes, voiceover and cuts. The free tool is the writing half of that workflow.
