AI Image Detector: Spot Deepfakes and AI Photos on iPhone and Mac

Romance scams stole $1.14 billion from consumers in 2023, the highest losses of any impostor fraud, says the FTC. Swindlers now spin up fake dating profiles with AI-generated faces and chatbots. Our AI image detector lives on your iPhone and Mac, so you can check if AI generated that selfie, receipt, or product shot before you swipe or buy. It flags watermarks plus subtle face artifacts the human eye misses.

AI Text Detector With Unlimited Word Count

Nearly 90% of students admitted using ChatGPT for homework in early 2023, and teen usage doubled again by 2025. Students and teachers often need to check long essays and lots of submissions - this is where cloud detectors fall short with word limits, and uploads. Slop Or Not runs locally on your iPhone and Mac, so you can paste any length and check as many documents as you need - no word caps, no usage limits, no cloud snooping. English today; more languages soon.

Two Readability Scores in One Tap

Slop Or Not shows readability scores alongside every text check, on-device in 7 languages, with no upload and no account. English uses Flesch Reading Ease and Flesch-Kincaid Grade Level; German uses Wiener Sachtextformel; Spanish uses Flesch-Szigriszt; Italian uses GULPEASE; Swedish, Danish, and Norwegian use LIX. The scores estimate how hard text is to read; they do not estimate whether AI wrote it. Scores are approximate.

Remove AI Fingerprints on iPhone and Mac

Cloud "AI humanizer" sites often pipe your words into remote LLMs that leave new fingerprints behind. Slop Or Not scrubs zero-width spaces, homoglyphs, and spacing tricks - like the binary pattern Elon Musk used in 2008 to catch a Tesla leaker - without rewriting your style. Apple Intelligence powered unlimited AI humanizer is coming soon to Slop Or Not.

How Slop or Not Catches AI Slop

Three detection layers, all on-device. No upload, no API calls, no waiting.

C2PA · IPTC

Watermark reads from C2PA and IPTC metadata

Many AI image generators stamp provenance signals into the file. Slop or Not reads two open standards: C2PA (used by OpenAI's image generation) and IPTC (used by Google and most major AI image tools). When a watermark is present, the verdict is 100% accurate.

OmniAID · arXiv

State-of-the-art on-device image model

When no watermark is present, OmniAID flags subtle artifacts the eye misses. It is a state-of-the-art on-device AI image detection model that runs entirely on the Apple Neural Engine.

Transformer · CoreML

Custom transformer for AI text detection

A custom-trained transformer model checks every passage for AI fingerprints. It runs on the Apple Neural Engine through CoreML — fully on-device, offline, with no word limit.

Accuracy is based on our internal tests. Results can vary with new AI models and advanced methods designed to trick detectors.

Who Uses an AI Slop Detector

Journalists & Fact-Checkers

Verify images and source quotes without uploading anything. On-device detection keeps investigations private - no OpenAI, Anthropic, or other cloud LLMs - so you can safely fact-check sensitive material before publishing.
