SlopProx is a Windows desktop app plus Chrome and Firefox extensions that detect and hide AI-generated text, images, and YouTube videos while browsing. Text analysis combines more than 76 curated phrases and structural signals with an on-device ONNX transformer. Image checks use three ONNX vision models and inspect C2PA manifests, EXIF data, and PNG metadata. The YouTube filter checks an AI disclosure before the player renders, then can overlay videos or dim feed and search cards. Optional Enhanced Mode uses a local HTTPS proxy to block 29 listed ad networks and installs a local certificate without administrator rights. The maker says all processing stays on the device, with no cloud calls, telemetry, or data leaving the machine. Integrations include email, Google Docs, and CMS workflows through the extension. The project is GPL-3.0 open source. Open Source costs nothing. Individual Pro is listed at £49 a year, and Teams at £10 a month, billed annually per seat with a five-seat minimum. Pro is marked coming soon.
