PPTDetector is an online AI content detector specifically built for PowerPoint presentations. Users upload PPT or PPTX files and the service performs multi-layered analysis—examining text patterns, image traces and slide structure—to identify content likely produced by AI models such as ChatGPT, GPT, Gemini or Claude. The platform generates fast, actionable reports with visualization, detection scores and highlights. It’s credit-based with trial and subscription plans, supports secure uploads via Google OAuth, and focuses on privacy and continuous model updates to improve detection accuracy over time.
