Crossplag
Crossplag checks whether pasted text was written by a human or generated by an AI chatbot, returning a confidence percentage after you paste copy into the detector at app.crossplag.com. The same company also runs plagiarism scans against more than 100 billion texts for students, academics, and bloggers.
Turnitin-style plagiarism tools flag copied sources; Crossplag pairs that similarity checking with a separate AI detector trained on over 1.5 billion parameters to score chatbot-written assignments, resumes, and blog drafts. The AI detector is free and does not consume plagiarism credits, which matters when you only need a quick originality check on marketing copy.
Inspera acquired Crossplag and now sells the education stack under Inspera Assessment, but the consumer AI detector and individual plagiarism plans still live on crossplag.com. It fits teachers screening student essays, bloggers verifying SEO drafts, and recruiters checking whether cover letters were chatbot-written. English is the only supported language for AI detection today.
