An undetectable AI humanizer with a built-in multi-detector checker
Paste AI-written text and uPass rewrites it with vocabulary and sentence structures that read like a person wrote it, rather than simple synonym swapping.
Check a passage against several popular detectors in a single run instead of submitting it to each service separately, and see where your text stands.
Select Basic, Advanced or Aggressive depending on how much restructuring the text needs while keeping the meaning intact.
The rewriter generates varied phrasing designed to keep output free of matches flagged by plagiarism checkers as well as AI detectors.
AI content detection and a full writing toolkit in one place
Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
