About OpenMontage

OpenMontage turns an AI coding assistant into a video studio. Describe the video you want in plain language and the agent does the rest. It handles research, scripting, asset generation, editing and the final render. Better image, video and voice models need paid API keys.

Best for: People who already use an AI coding assistant and want narrated explainers, trailers or animated shorts.

• Runs 12 production pipelines, from explainers to documentary montages
• Turns a pasted YouTube, Short, Reel, TikTok or local clip into a plan
• Shows a live storyboard: stages, scene cards and spend as the run goes
• Pauses asset generation so you approve each scene before the render
• Runs free with Piper TTS, open archives and Remotion or HyperFrames
• Checks the file before delivery: ffprobe, frames, audio levels, subtitles
