On-device AI text and image detector for iPhone/Mac that flags AI-generated writing and photos without uploading data.
What it does
Slop or Not is an on-device AI detector for iPhone and Mac that checks whether text or photos were AI-generated. It runs locally on Apple Neural Engine using models trained on human and AI samples, so nothing is uploaded to a server. It also flags outputs from specific tools like ChatGPT, Gemini, DALL-E, and Midjourney, and includes readability scoring and CLI/MCP tooling for developers.
