FAQ

Frequently Asked Questions

Is Stop the Slop 100% free? +
Yes! Stop the Slop is 100% free, open-source under the MIT license, and contains no ads or paywalls.
How accurate is the AI detection score? +
Detection is powered by advanced AI linguistic analysis via Sapling AI and heuristic pattern detectors. While it provides strong indicative probabilities of LLM-generated phrasing, results are advisory rather than 100% conclusive.
What data does the extension collect? +
Zero personal data is collected. The extension only reads the video ID and transcript on the YouTube watch page you are currently viewing to perform the analysis. See our Privacy Policy for full details.
Does it work on videos without subtitles? +
The extension requires a transcript to analyze. It works seamlessly with both manual creator subtitles and YouTube's auto-generated captions. If a video has all captions disabled, analysis cannot be performed.
