TL;DR
OpenMontage is an open-source, agentic video production system that turns any AI coding assistant — Claude Code, Cursor, Copilot, Windsurf, or Codex — into a full video production studio. You describe what you want in plain language ("Make a 60-second animated explainer about how neural networks learn"), and the agent handles research, scripting, asset generation, voice direction, editing, subtitles, music, and final composition.
