Educational videos

Paste your lesson notes, a textbook section, or a concept you want explained. The agent breaks it into one idea per scene, draws each one on screen, and narrates it with word-timed subtitles, so students can watch, pause, and replay the explanation.

Good things to paste

  • Lesson notes or a lesson plan
  • A textbook section or study guide
  • A concept list for exam revision
  • A lecture outline for a flipped classroom
One idea per scene
Each scene gets a single drawing and a short stretch of narration, which keeps the cognitive load low.
Subtitles burned in
Word-timed subtitles help students who watch without sound or are still learning the language. You also get an SRT file.
Narration in the class language
The narration follows the language of your notes, or ask for another one, such as a Spanish version of an English lesson.
Faithful to your material
The agent works from the text you paste and is told not to invent facts, so the video teaches what your lesson says.

    Download the MP4 and SRT for your LMS, YouTube channel, or slides.

Questions, answered

How do I get the level right for my students?

Say who the video is for in your message, for example "for a 5th-grade class" or "for first-year university students". The narration and examples are pitched at that level.

Can I make the same lesson in another language?

Yes. Ask for the narration language you need. The video is re-created in that language and charged as a new video.

How long can a lesson video be?

Up to 5 minutes. For longer topics, split the lesson into several short videos, which also works better for students.

Can I upload a PDF of my slides?

Yes. Attach a PDF, PPTX, or DOCX with the paperclip. The text is extracted in your browser and only that text is sent; the file itself never leaves your computer. Slides keep their order, and speaker notes become the narration.
