Clipper

Open-source alternative to OpusClip, Descript & Submagic. Turn long recordings into viral shorts for TikTok, Reels & YouTube Shorts — runs fully local, bring your own API key, no subscription, no watermark.

Mac only for now. Windows support planned.

What it does

• Transcribes video locally via Whisper (no data leaves your machine)
• AI detects the best clips with scores and reasons
• Review, trim, and approve clips in a visual editor
• Export clips as 9:16 vertical video with burned-in subtitles
• Export full episode with filler words and silences removed

Prerequisites

• macOS
• Homebrew
• Groq API key (free — used for AI clip suggestions)

Setup

git clone https://github.com/PriyeshPandey2000/ai-video-clipper.git
cd ai-video-clipper
bash scripts/setup.sh

The script installs Node.js, pnpm, dependencies, and the bundled FFmpeg. It also creates a .env template.

Add your Groq key to .env:

GROQ_API_KEY=your_key_here

Run

pnpm dev

How it works

1. Drop a video file into the app
2. Pick a Whisper model and click Transcribe
3. AI suggests the best clips — review and approve
4. Toggle 9:16 reframe if needed, drag to set crop position
5. Click Export Clips or Export Episode
