OmniDetect

OmniDetect checks writing for signs of AI generation and marks which passages read as machine-written, how strongly, and what to change before re-checking. It is aimed at students, writers and marketers who want to review a draft before submitting it.

You can paste text, upload PDF, DOCX or TXT files, or scan a URL, and optionally tell it whether the writer is a native speaker or used a grammar tool, and what kind of text it is. Scores run from likely human to likely AI, with the evidence shown alongside.

The company publishes its measured accuracy, including misses, and says the result never decides authorship or misconduct. The interface is available in nine languages, and paid access is sold as a 7-day pass with no auto-renewal.
