Explainer Video Script Builder

Write a 60-90 second explainer video script for any product or service

Generates an explainer video script with a problem hook, solution reveal, how it works in three steps, a social proof line, and a CTA — complete with per-scene timing notes.

Why 60–90 seconds?

Explainer videos peak in retention between 60 and 90 seconds — long enough to show value, short enough to hold attention. At a natural narration pace of about 150 words per minute, that is roughly 150–225 words, which this tool targets.

A timed explainer script that holds attention

The best explainer videos follow a tight emotional arc: name a problem the viewer feels, reveal the solution, show it working, prove it, and ask for one action. Doing that in 60–90 seconds takes discipline because every second counts. This builder turns your product details into a scene-by-scene voiceover script and estimates the runtime of each scene so you know the whole thing fits before you ever hit record.

How it works

The tool assembles five scenes in the proven explainer order and times each one. The hook opens by dramatising the problem so the viewer recognises themselves. The solution reveal introduces your product as the turning point. The how it works section breaks the experience into three simple steps, because three is the number a viewer can hold in memory. The proof scene adds a single credibility line — a customer count, a result, or a rating. The CTA closes with one clear instruction. Each scene’s duration is estimated from its word count at roughly 150 words per minute, and the tool sums them so you can keep the total inside the 60–90 second sweet spot.

Tips and example

  • Make the hook visceral: “It’s 9pm and you’re still chasing an unpaid invoice” lands harder than “Invoicing is hard.”
  • Keep each of the three steps to one short sentence so the matching visual is easy to storyboard.
  • Use exactly one proof point — a number beats a paragraph.
  • End with a single action (“Start your free trial at example.com”), not a list of options.

If the total runs over 90 seconds, cut adjectives and merge steps; if it runs under 60, add a sharper proof line or a second benefit. Aim to land squarely in the middle for the strongest retention.
