OmniDetect

OmniDetect is an AI content detection tool that analyzes text to identify which passages were likely written by AI, how strongly, and what to change. It provides transparent evidence behind every verdict, showing the analyzed scope, method status, and known limits rather than just a mysterious percentage. Users can paste up to 50,000 characters, upload files (.pdf, .docx, .txt), or scan a URL. The tool supports multiple writer profiles (ESL, native speaker, professional, grammar-edited) and text types (academic essay, blog post, SEO, creative writing, business, technical).

What is OmniDetect?

OmniDetect is a web-based AI detector that reads submitted text and returns a verdict (Likely Human, Uncertain, or Likely AI) along with the specific passages that triggered the result. It uses multiple detection engines chosen by its own benchmark, and it keeps a copy of submitted documents in user history until deleted. The tool is designed for students, writers, and professionals who need to verify the authenticity of their writing before submission.
