## Quick answer

An AI explainer video generator turns a topic into a narrated video: a script, one illustration per scene, a voiceover and captions. Korpi has a separate creator for each explainer style. Choose the style that fits the topic, enter the subject, review the script and scenes, then render. Use the list below to choose.

## Choose a style by topic

The default format is where each creator starts. Check the format setting in the creator before you render.

## How an explainer is made in Korpi

1. **Pick the creator and topic.** Generate a script from a subject or paste your own. Scripted explainers keep one idea per scene so each illustration can carry it.
2. **Review the scenes.** Korpi generates one image per scene in the creator's locked style. Regenerate any scene that does not match the narration.
3. **Add narration and render.** Choose a voice, keep captions on for phone viewers, add music if you want it, and render.

## What makes an explainer worth watching

- **One concrete number or fact early.** It gives the viewer a reason to keep watching.
- **One idea per scene.** Viewers drop off when a picture and a sentence say different things.
- **Facts you can source.** The Vox Explainer creator tags every scene as sourced, estimate or framing ([step-by-step guide](/blog/how-to-make-vox-style-explainer-videos)). Check sourced claims before you publish.
- **A consistent look.** Switching styles mid-series makes a channel harder to recognise. Pick one creator per series.

## Other tools

If you mainly need standalone images, cinematic clips or ads, a general creative suite may fit better; see [Korpi vs Higgsfield](/blog/korpi-ai-vs-higgsfield) for a sourced comparison. For channel planning, see [faceless YouTube channel ideas](/blog/faceless-youtube-channel-ideas).

Watching examples is free. Generating and exporting your own explainer requires a paid plan, and AI generation uses credits. [Compare plans](/#pricing).

## FAQ
