Overview
PSL Rating and AI or Not are two distinct AI-powered tools that serve different purposes. PSL Rating focuses on facial aesthetics, providing a score on a 1-8 PSL scale based on harmony, dimorphism, angularity, and presentation. It processes photos entirely in the browser, ensuring privacy. AI or Not is a multimodal content detection tool that identifies AI-generated text, images, video, and audio, with a strong emphasis on text analysis for detecting content from models like ChatGPT and Claude.
