AI Explainer Video Generator for History, Science and Psychology

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.

How an explainer is made in Korpi

1. 1Pick 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. 2Review the scenes. Korpi generates one image per scene in the creator's locked style. Regenerate any scene that does not match the narration.
3. 3Add 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). 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 for a sourced comparison. For channel planning, see 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.

FAQ

What is the best AI explainer video style for history?

It depends on the angle. Vox Explainer suits evidence-led history with maps and charts, Stickman History and Origami History suit one story told from the inside, and Documentary 3D suits mysteries and true crime.

Can Korpi make science explainer videos?

Yes. Claymotion covers deep-time science and prehistory in clay stop-motion, and Paper Stop-Motion covers science, history and mystery stories in layered cardstock.

Both exist. Vox Explainer, Stickman History, Origami History, Paper Stop-Motion and Sticker Explainer start vertical for Shorts, TikTok and Reels. Claymotion, Documentary 3D, Education Explainer, Cartoon Explainer, Whiteboard Animation and Stickman Finance start in 16:9 widescreen.

No. Watching example videos is free, but generating and exporting your own explainer requires a paid Korpi plan, and AI generation uses credits.
