Lesson presentation: slides, handout and narrated video

From Wikipedia articles on the lesson topic and from Wikimedia Commons. They are freely licensed images; the author and licence are printed under the photo and gathered on a credits slide — exactly what CC-BY and CC-BY-SA require. Images are deliberately not generated by a neural network: a lesson needs factual accuracy, and generators draw plausible but invented maps and diagrams and mangle lettering.

The length shown is measured from the finished narration. If it differs from your request by more than 8 %, a fit button appears: the narration is extended or tightened by the required number of words and the lesson is re-narrated. The tool will not pad the clip with silence — a five-minute lesson containing a minute of silence is worse than an honest three-minute one.

Headings, lists and captions are exported as native shapes rather than as a picture of the slide, so text stays text in PowerPoint and LibreOffice and can be edited. The font is Arial: school computers have it, so nothing gets substituted.

Yes, there is a separate mode for it. Pasted notes are laid out as slides without calling a language model: the key points go on screen, the full paragraph becomes the narration. In this mode the length is not ordered — it follows from your text.

The slide stays textual. That happens with abstract topics — school mathematics, for instance, where diagrams replace photographs. Check the image query in the plan: a concrete subject (“reindeer”) is found far better than a concept (“animals”).

No. A language model gets dates, numbers and names wrong, and a whole class watches the lesson. The tool prepares a draft and lets you edit every word — checking the facts before the lesson is the teacher’s job.
