Heynotai vs SlopProx

Heynotai detects whether text, images, audio, video, essays, headshots, voice notes, and deepfakes are likely AI-generated. Users can paste text, drag in images, attach a voice memo, or link a YouTube video. Results are labeled likely human, likely AI, or uncertain with a probability rather than a binary answer. Reports can show model breakdowns, flagged regions, confidence intervals, PDF export, and an audit trail. One API lists detectors for text, image, audio, video, deepfake, voice clone, watermark, and paraphrase. The extension supports Chrome MV3, Edge, and Brave, and can add a colored trust border to YouTube players. The Check plan costs nothing with 100 tokens per month for text and image detection. Verify costs $8 a month billed annually, and Certify costs $25 a month billed annually. Text and image checks can run locally; audio and video use the opt-in API.

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.
