 "title": "Make a narrated explainer video from one topic",
 "page_title": "How to make a narrated explainer video from one topic with Explainroo",
 "summary": "Give a coding agent a topic and get a narrated MP4 with drawn scenes and subtitles.",
 "who": "A teacher, founder or content creator who needs a short explainer on one topic and does not want to edit video by hand.",
 "problem": "Making an explainer video usually means writing a script, recording a voice, drawing scenes and syncing them by hand.",
 "outcome": "An MP4 where a local voice narrates the script and drawings appear on the words they match, plus subtitle files and a cover image.",
 "steps": [
  "Clone the repo with `git clone https://github.com/vincentsch/explainroo.git`",
  "Enter the folder with `cd explainroo` and install dependencies with `npm install`",
  "Download the voice and timing models with `node bin/explainroo.js doctor --fetch`",
  "Start your coding agent in the Explainroo folder and give it the topic prompt below",
  "Open the MP4 the agent saves under videos/ and watch it to confirm the narration matches the drawings"
 ],
 "agent_prompt": "Use the explainroo repo at <repo folder> to make a short explainer video about <topic>. Read AGENTS.md and follow its steps so the agent writes script.md and scenes.js and renders an MP4. Expected output: one MP4 under videos/. Verify that the voice reads the script without wrong words before you report the file path.",
