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. ```text Install Micro-Lesson Maker and tell me when I need to sign in: https://beatra.ai/skills/micro-lesson-maker/install.md ``` Send it to WorkBuddy, Codex, Claude Code, or another agent to install.

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 ### Script per slide · 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 ### The teacher's presence · 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 ## Contests, demo lessons, and everyday teaching ### Micro-lesson contests Turn a contest topic into a 5-to-10-minute micro-lesson video with slides, narration, and subtitles. ### Open and demo lessons Record an open lesson or a demo lesson as a video to rehearse with and to share with colleagues. ### Preview and review lessons Give students one short video per topic to watch before class or to review after it. ## Inputs and outputs | Input or output | Type | Formats | Specifications | | --- | --- | --- | --- | | Input | Document — Slide deck as a PowerPoint file or a PDF | PPTX, PDF | — | | Input | Image — Or a folder of slide images exported from PowerPoint or WPS | — | — | | Input | Text — Or one lesson topic, when there are no slides yet | — | — | | Input | Image — Teacher's photo for a corner portrait or an on-camera opening (optional) | JPG, PNG | 1 image per request | | Input | Audio — Voice sample for a cloned voice (optional) | — | 10–300 s; up to 20 MB each | | Output | Text — Spoken script for every slide | — | editable | | Output | Document — Editable deck drafted from the lesson outline, when there were no slides | PPTX | editable | | Output | Video — Micro-lesson video with slides, narration, and on-screen subtitles | MP4 | — | | Output | Text — Subtitle file beside the video | SRT | — | | Output | Audio — Narration only, one file per slide in slide order, on request | MP3 | — | Specifications last checked 2026-11-09 · Sources: [Model catalog](https://docs.beatra.cn/en/docs/models) · [Documentation](https://docs.beatra.cn/en/docs/mcp-tools) · [Terms of Service](https://www.beatra.cn/en/terms) ## 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. ## Related Skills - [Lesson Plan to Micro-Lesson Video](https://www.beatra.cn/en/skills/micro-lesson-teacher): Get the lesson plan, every slide, and the script written first, then the courseware and a narrated micro-lesson video. - [MiniMax H3 AI Video Creator](https://www.beatra.cn/en/skills/minimax-h3-ai-video): Bring ads, products, brands, dynamic posters, game moments, and social stories to life with cinematic movement and native stereo sound. - [MOOC Video Producer](https://www.beatra.cn/en/skills/mooc-producer): Get the chapter plan and lesson 1 scripted first, then every lesson narrated over your slides in your own voice, with subtitles. - [Music Video Director](https://www.beatra.cn/en/skills/music-video-director): Get the shot list, key visual, and titles first, then the frames and clips set to your song, or a photo that sings.
