How it works / end to end
From YouTube card to explainable verdict.
01Browser extension
Scan the feed
SlopShield reads video and channel IDs from ordinary YouTube cards and applies cached verdicts immediately.
02Evidence
Fetch only when needed
For an unknown channel, the browser supplies one timestamped transcript through your active YouTube session.
03Analysis engine
Find and verify the signal
Contextual text analysis locates a suspicious segment; synthetic-speech detection checks only that audio slice.
04Feed result
Clean without breaking YouTube
AI-classified cards are hidden. Safe, pending, failed, and unavailable checks stay visible with honest status badges.
Analysis engine / 3 stages
Parse the transcript
The browser supplies a timestamped transcript only when cached evidence is missing.
Select the signal
Four context windows identify the strongest suspicious segment.
Analyze the voice
Only that segment is downloaded and checked for synthetic speech.
Built with restraint / honest by default
Protection without surveillance theatre.
Minimum evidence
Cached channel verdicts avoid repeated transcript collection. New evidence is requested only when needed.
Visible uncertainty
Failed, pending, and unavailable checks remain visible. SlopShield does not turn missing data into confidence.
Open implementation
The extension and inference engine are open source, so the filtering flow can be inspected and challenged.
Take back the feed
Make “No AI detected” the result worth seeing.
Install the browser extension, inspect the implementation, or run the analysis engine yourself. SlopShield is an open Build Week project.
