What Pexo Does

Everything you want from a how it works video generator

Text & image to video

Turn a prompt or a screenshot into an AI how it works video

Start from one line of text, a screenshot, or a full script. Pexo writes the beats, generates every shot, and stitches them into one continuous edited cut. Each shot is routed to the model that renders it best, Seedance 2.5, Kling AI 3.0, MiniMax H3, or Happy Horse 1.0, so screens stay legible and motion stays calm. No timelines, no keyframes, no editor to open.

A how it works video maker that plans the steps for you

Pexo splits your product into a handful of steps, opens on the problem, and shows how each part solves it, which is the same spine a great explainer video runs on. Whether it is a technology explainer video or a two step signup flow, the narration stays in plain language and the pacing stays patient but tight. You go from a feature list nobody reads to a sequence people follow.

Step by stepPlain languageProblem to payoff
Show, do not tell

Show the screen, not just the story

Pexo numbers each step, highlights the control that matters, and holds on screen long enough to read, so viewers follow without scrubbing back. Ask for a plain screen walkthrough or a whiteboard explainer video and the same numbered steps get rebuilt in that style. An infographics explainer video or a 3d animation explainer video works the same way, with every step carried over shot for shot. It teaches by showing instead of narrating at people.

Answer the objection

Answer the question that stalls the signup

Tell Pexo the objection you hear on every call and it places the answer in the shot where the doubt shows up, in plain language, before anyone clicks away. Setup time, data safety, migration effort, whatever stalls the deal gets handled inside the how it works video instead of in a follow up email. Viewers leave with the question already closed.

One how it works video, every aspect ratio

Pexo delivers the same steps as a 16:9 youtube explainer video, a 9:16 cut for TikTok and Reels, and a 1:1 version for feeds, up to 4K and anywhere from 5 to 120 seconds. Each ratio is generated fresh for that screen, framed for it rather than cropped down from one master. Ask for several formats at once and post the right one to every channel.

Teams are getting their products understood with Pexo

Prospects kept telling us they did not get it. Pexo turned our onboarding flow into a numbered walkthrough in an afternoon and demo signups climbed the same week.

I typed six steps and Pexo scripted, narrated, and captioned the whole thing at 4K. That was a week the design team got back.

The 40 second cut lives in our onboarding email now, and tickets asking how the basics work have thinned out every month since.

How it works video questions

What is a how it works video?+

A how it works video is a short explainer that shows the mechanism behind a product, walking viewers through each step from the problem to the result. It runs on real screens rather than descriptions, usually lands between 30 and 90 seconds, and ends where the payoff is obvious. Pexo builds one from a written description of your steps with text to video.

How long should a how it works video be?+

Under 90 seconds. A 30 second explainer video carries one core step, and 60 to 90 seconds is enough for three or four without rushing the narration. Pexo renders anywhere from 5 to 120 seconds up to 4K, so you can cut a short social version and a longer site version from the same how it works video.

Can I use my own screens, narration, and captions?+

Yes. Bring screenshots or screen recordings and Pexo turns them into numbered steps with image to video, keeping the interface crisp instead of swapping in stock visuals. It writes the voiceover, clones a voice when you want a familiar one, burns in captions, and dubs the finished cut into other languages for the same steps.

What is the best AI tool for a how it works video?+

Pexo. It puts Seedance 2.5, Kling AI 3.0, MiniMax H3, and Happy Horse 1.0 behind one prompt box and routes each shot to the model that renders it best, then returns 16:9, 9:16, and 1:1 up to 4K. You describe the steps and the script, voiceover, captions, and edit come back finished.

How is this different from an explainer video?+

Scope. A good explainer video sells the idea, while a how it works video shows the mechanism step by step. Use explainer video when the pitch is the job, product demos for a full feature tour, and this page when the mechanism is the part people keep missing.

How do I write a good prompt for a how it works video?+

Use subject + action + camera movement + setting + style. Example: a hand tapping through a booking app, slow push in on the screen, bright studio desk, clean product walkthrough style. Add how many steps you want and the length, and Pexo builds the script, the shots, and the captions around that.
