Micro-lesson video maker
Turn one lesson into a micro-lesson video
Micro-Lesson Maker turns one lesson's slide deck, or a single topic, into a 5-to-10-minute micro-lesson video, and drafts an editable deck in lead-in, explanation, worked example, and summary when there are no slides yet. Every slide then gets a spoken script, narration, and subtitles, with the teacher's photo or a digital-human teacher opening the lesson, delivered as one MP4 with an SRT subtitle file. Micro-Lesson Maker works in Claude Code, Codex, Cursor, and other agents that run Skills.

One lesson, one finished micro-lesson video
Slides or just a topic
Use this lesson's slides as they are, or start from a topic and a grade with an editable 6-to-10-slide deck.
A script for every slide
Speaker notes become the script, and every other slide gets one written for the grade, ready for the teacher to adjust.
The teacher on screen
Place the teacher's photo in a corner, or open the lesson with a digital-human teacher.
How it is made
Use the lesson's slides, or start with a fresh deck
Bring this lesson's slides as they are. With only a topic and a grade, 6 to 10 slides are drafted in lead-in, explanation, worked example, and summary for the teacher to edit.
Use the lesson's own slides · Draft a deck from a topic · Edit it in PowerPoint or WPS
Every slide gets its spoken explanation
Speaker notes become the script; a slide without notes gets one written from what it shows, for the grade and in the teacher's register.
Use speaker notes as the script · Settle readings of names and terms · Subtitles on the video
A corner photo or a digital-human opening
Place the teacher's photo in a corner, open the lesson with a digital-human teacher made from one photo, and explain every slide in the teacher's own voice.
Add a corner photo · Open with a digital-human teacher · Explain in the teacher's own voice

Micro-lesson contests

Questions
Can I start without slides?
Yes. The topic and the grade are enough: you get an editable deck in lead-in, explanation, worked example, and summary, and the micro-lesson video made from it.
Can it use my own voice?
Yes. Your voice is cloned once, and the cloned voice explains every slide.
What will I receive?
A 5-to-10-minute micro-lesson video with its subtitle file and the script for every slide; when you started from a topic, the editable deck too.
