The narration can use a clone of the teacher's own voice, made once for the whole course, and a digital-human teacher made from one photo can open and close each lesson. Lecture Video Maker works in Claude Code, Codex, Cursor, and other agents that run Skills. ```text Install Lecture Video Maker and tell me when I need to sign in: https://beatra.ai/skills/lecture-video-maker/install.md ``` Send it to WorkBuddy, Codex, Claude Code, or another agent to install.
