What Is an AI Clip Maker?
A 3-hour stream or 90-minute podcast contains moments worth sharing. Finding them manually means scrubbing through hours of timeline. Drop a video, pick your content style, and the app surfaces the most engaging segments in seconds.
How Highlight Detection Works
The engine scans audio for volume spikes, energy shifts, and pace changes. It measures three signals: overall loudness (RMS), zero-crossing rate (separates speech from noise), and peak amplitude. Loud moments in quiet sections score highest.
Each content style adjusts detection. Gaming mode hunts for loud peaks and fast transitions. Podcast mode tracks steady vocal energy. Comedy mode watches for sharp audio spikes after punchlines. The system returns the top three non-overlapping segments.

What is an AI Highlight Finder?▼
Scans any video file and pinpoints the most interesting moments. Drop a file, pick a content style, and receive three curated clips with precise timestamps ready for editing or publishing.
How does AI find the best moments in a video?▼
The system measures three audio signals across the entire video: RMS energy (overall loudness), zero-crossing rate (separates speech from noise), and peak amplitude. High-energy moments score higher. Different style modes adjust which signals carry the most weight.
Does my video get uploaded to a server?▼
No. Your video stays on your device. All processing runs locally in your browser using the Web Audio API and Web Workers. There is no upload step, no server-side processing, and no cloud storage.
Is there a file size limit?▼
No server-imposed limits because nothing is uploaded. Desktop browsers typically handle up to 2 GB depending on available RAM. Mobile browsers work best with files under 500 MB.
Can I create YouTube Shorts from long videos?▼
Yes. The tool identifies 30 to 90 second segments that work as starting points for YouTube Shorts, Instagram Reels, and TikTok posts. Each clip comes with accurate timestamps you can paste directly into any video editor.
