EduBrain's AI Detector lets you paste in a piece of writing and see how much of it may have come from AI tools such as ChatGPT or Gemini. You get a percentage score and an estimate of the risk that your work will be flagged.
It supports several AI models and also links to a humanizing tool and expert help for revising content. It suits students, teachers and writers who want to check text before submitting it. Basic checks are free.
