How it works

You bring the brief. ClipNova makes the explainer.

Here is one project followed from the input to the export: a 90-second explainer on how a heat pump warms a home.

  1. Picture of AI Explainer Video Generator — a short written brief next to an uploaded PDF, the two ways to start

    Your input

    Start from a brief, a script or a document

    Type what the explainer should cover and who it is for, paste the script you already have, or upload a PDF, Word document or text file. ClipNova reads it and builds the video around the points that matter.

  2. Picture of AI Explainer Video Generator — the explainer planned as six numbered scenes, each with its line of narration

    Narration

    The narration is written and timed for you

    The brief becomes a spoken narration, one clear point per scene, and the video length is sized to it. Already have a script? Paste it and the voiceover follows your words.

    Visuals

    Every point gets its own scene

    Choose Moving AI Images, illustrated scenes with motion that cost a fraction of video, or AI Video for filmed-looking shots. Pick a style once and it holds across the whole explainer; at the higher image quality, recurring characters stay the same from scene to scene.

    Voice & captions

    A natural voiceover with synced captions

    Pick a voice and the narration is recorded for you, then captions are added in the style you choose. Voiceover and captions are on by default, so the explainer still lands with the sound off in a feed or a muted sales deck.

    Final video

    Export it, embed it, update it

    Download 16:9 for your website, YouTube or a deck, or 9:16 for social, with optional background music, up to 5 minutes. Watermark-free on every paid plan. When the product changes, edit a scene in the Studio instead of starting over.

Why an AI explainer video generator

An explainer used to take a studio and six weeks.

A classic explainer video goes through a scriptwriter, a storyboard artist, an illustrator, an animator and a voice actor, and it costs thousands before the first revision. Most of that work is translating a clear idea into pictures and a voice.

ClipNova does that translation in one generation. The narration is written from your brief or document, every sentence gets a scene that illustrates it, and the voice and captions come from the same script, so they line up without an editor. Changing the explainer means changing the text.

That makes it practical to have more than one: a homepage explainer, a version per customer segment, an onboarding video per feature. If you are still comparing tools, our roundup of the best AI explainer video generators covers the alternatives side by side.

AI explainer video generator questions.

What is an AI explainer video generator?+

A tool that turns a script, a brief or a document into a narrated video that explains a product, a process or an idea. In ClipNova it writes the narration, generates a scene for each point, records the voiceover and adds captions.

Can I upload a document instead of writing a prompt?+

Yes. Prompt to Video accepts PDF, Word (.docx) and text files up to 20 MB. Text-based PDFs work best; a scanned PDF has no text to read.

Do I need to write the script?+

No. The narration is written from your brief and the video is sized to it. If you already have a script, paste it and the voiceover follows it.

Illustrated scenes or video clips?+

Moving AI Images, illustrated scenes with motion, suit most explainers and cost far less per second. AI Video gives filmed-looking shots for product and lifestyle explainers, and is available on paid plans.

How long can an explainer be?+

Up to 5 minutes per video. Most product explainers work best at 60 to 90 seconds.

Can I edit it afterwards?+

Yes. Open the video in the Studio to change a scene or its narration line and re-render, without regenerating the whole explainer.

How much does it cost?+

New accounts get 70 free credits to try it, with no card required. Paid plans start at $19 a month for 1,000 credits and include watermark-free downloads and commercial rights.
