AI Video Commentator That Narrates Your Videos

An AI video commentator is a tool that uses artificial intelligence to watch your video, understand what's happening in each scene, and automatically generate narration or commentary. It then voices the narration using AI text-to-speech and mixes it with your original audio to produce a fully narrated video.

Our AI uses advanced video understanding models to analyze your footage frame by frame. It identifies objects, actions, people, scenes, and context to write commentary that accurately describes the on-screen events. It picks up on key moments, dramatic changes, and important details.

We offer 9 distinct OpenAI voices with different characteristics — varying in gender, pitch, tone, and style. You can preview each voice before generating and pick the one that best fits your content, whether it's a deep authoritative narrator or a casual conversational commentator.

Yes! After the AI generates the narration text, you can review and edit every line before the final video is rendered. You can tweak wording, add your own jokes or observations, adjust timing, or rewrite sections entirely while keeping the rest.

The four tones are: Documentary (serious, factual, educational style like a nature documentary), Funny (witty, playful, reaction-style humor), Dramatic (intense, suspenseful, building tension), and Engaging (energetic, upbeat, keeping viewers hooked). Each completely changes the feel of the narration.

Yes. The AI intelligently mixes the commentary with your original video audio. Background sounds, music, and dialogue are preserved at a balanced level so the narration enhances your video without drowning out important audio elements.

The AI video commentator supports all common video formats including MP4, MOV, and WebM. You can upload clips from a few seconds to several minutes long. The AI adapts the commentary density based on the video length and content.

AI video commentary with StoryShort costs a fraction of hiring a voiceover artist. While professional voiceover work typically costs $50-300+ per video, AI commentary can be generated for under $1, making it possible to narrate content at scale.
