Sapling AI Content Detector

Categories: Productivity, Research, Education | Pricing: Freemium | Official Website ↗

Detects whether text is AI-generated by models like ChatGPT or Gemini, providing a probability score and highlighting suspicious sections.

Sapling AI Content Detector is a tool that identifies machine-generated text, often referred to as "AI slop," from various AI models including GPT-5, Claude, Gemini, Qwen, and DeepSeek. It uses a machine learning system (a Transformer) to generate the probability that each word or token in the input text is AI-generated. The tool provides an overall score and highlights portions of the text and individual sentences that appear to be AI-generated due to low perplexity measures. The detector is designed to assist educators, SEO practitioners, and reviewers of user-generated content in screening for synthetic content. It supports text input, as well as PDF and DOCX file uploads, and offers a Chrome extension for detecting AI content anywhere on the internet. Sapling regularly retrains and finetunes its detector to stay current with the latest AI models.
