 "title": "Make an animated explainer with no paid API keys",
 "page_title": "How to make an animated explainer with no paid API keys with Open Montage",
 "summary": "Generate a narrated animated explainer using free Piper narration and Remotion composition.",
 "who": "A teacher or developer who wants a short explainer video and has no budget for paid AI services.",
 "problem": "Most AI video tools need paid accounts before a first video can be made, which blocks quick experiments.",
 "outcome": "A rendered 60-second animated explainer with offline narration, built from the free tools in the default setup.",
 "steps": [
  "Install prerequisites and run `make setup`.",
  "Leave the .env keys empty, since every key is optional.",
  "Open the project in your AI coding assistant.",
  "Send the request: \"Make a 60-second animated explainer about how neural networks learn\".",
  "Watch the render and check that the narration and subtitles are correct."

 "agent_prompt": "In the OpenMontage repo at <repo-path>, produce a 60-second animated explainer about <topic> using only free tools such as Piper TTS and Remotion. Save the final MP4 and verify with ffprobe that the duration is about 60 seconds.",

 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The README describes Piper as free offline narration, but the visual quality of zero-key output depends on the free stock and Remotion scenes the agent can build.",
