Explainer Shorts Generator: How Things Work in Under a Minute

Start from a question, not a subject

“Satellites” is a subject; “How does GPS know where you are?” is a question, and a question gives the writer a finish line. Good explainer topics usually start with how or why and can be answered in three to six steps.

Looks that suit explaining

Chalkboard draws each beat as chalk doodles on a green board and asks the narrator to sound like a patient teacher. Low Poly builds clean, faceted 3D scenes with a friendly tech-explainer delivery, which suits machines, space and maps. Documentary keeps things grounded in real-looking places when the topic is about the physical world. Vaporwave works surprisingly well for anything about old computers or the early internet.

One beat per step

A Quick short has five beats and an Extended one has eight, and each beat is one picture on screen. When you plan an explanation, think of it as that many slides: a hook, the steps, and a final line that ties the answer together. If you write your own script, put each step on its own line so the pictures change with the steps.

Keep it checkable

Drafts come from an AI model and general knowledge, so numbers and dates are worth a second look. Every short’s page lists the narration beat by beat, which makes it easy to check against a source before you post it.

From a sentence to a short in three moves

Step 1

Start with words

Type a topic in a line, or paste a script you have already written. A topic is drafted into narration sized to the length you pick; a script is read word for word.

Step 2

Choose how it looks and sounds

Pick one of ten looks, from film noir to chalkboard, and one of ten narrator voices. The look sets the pictures, the caption colour and the way the narrator delivers the lines.

Step 3

Get a finished vertical video

Each beat gets its own picture, the voiceover is recorded, captions are timed to every spoken word, and it all lands as a 1080×1920 MP4 in your library.

Explainer shorts: questions

Can the pictures include labels or written steps?

Not reliably. Picture prompts ask for no lettering, and the words are carried by the captions instead. If you need a labelled diagram, add it in an editor afterwards.

What length suits an explainer?

Standard, at about forty-five seconds, fits most how-it-works questions. Use Quick for a single fact with a reason, and Extended when there is a sequence of four or more steps.

Can I use an explanation I already wrote?

Yes. Switch to script mode and paste it. It is read word for word, and the counter tells you whether it fits the length.
