Stop the Slop: AI Script Detector for YouTube

• Real-time AI Detection: Analyzes YouTube video transcripts in real-time to identify AI-generated content, robotic narration, and recycled scripts.

• Privacy-First: A free, open-source browser extension with zero tracking, no login required, and no tracking cookies. Video transcripts are processed locally for analysis.

• Intuitive Interface: Features AI probability gauges and sentence-by-sentence linguistic heatmaps displayed directly on the YouTube page.

• Thumbnail & Feed Badges: Receive instant AI probability badges on video thumbnails in your Home feed, Search, and Recommendations.

• Sentence-Level Heatmap: Inspect a detailed breakdown to pinpoint specific robotic sentences and repetitive formulas that triggered the AI detector.

• Performance Optimized: Utilizes Cloudflare Edge Caching for sub-100ms instant verdicts on analyzed videos.

• Adaptive Design: Seamlessly matches YouTube's dark and light aesthetics with automatic OS system preference detection.

• Multi-Browser Compatibility: Built on modern Manifest V3 standards, compatible with Google Chrome, Brave, Microsoft Edge, Opera, and Mozilla Firefox.

How it Works:

1. Extract Transcript: The extension non-intrusively extracts official or auto-generated subtitle tracks directly from the YouTube page.

2. Edge AI Evaluation: The transcript is analyzed via a fast Cloudflare Worker API to detect typical LLM stylistic markers, sentence perplexity, and repetitive filler formulas.

3. Instant In-Page Score: Receive an intuitive probability gauge and an itemized breakdown of flagged sentences in the extension popup and on-screen badge.

Stop the Slop is 100% free, open-source under the MIT license, and contains no ads or paywalls. It requires a transcript to analyze and works with both manual creator subtitles and YouTube's auto-generated captions.
