Tool Information

ZeroGPT platform architecture and DeepAnalyse detection engine

ZeroGPT (accessible at zerogpt.com) is a free and accessible artificial intelligence text detector, plagiarism checker, and text analysis platform. Designed to provide fast and open AI detection, ZeroGPT is used by millions of students, teachers, content writers, and editors to evaluate whether text was generated by AI models.

The platform is anchored by proprietary DeepAnalyse Technology, which assesses linguistic predictability and sentence patterns. ZeroGPT features Sentence-Level AI Highlighting (flagging individual sentences as AI-generated with highlighted text overlays), an AI Humanizer, Text Summarizer, Grammar & Spell Checker, and multi-file batch upload support.

Core detection capabilities and ZeroGPT tools

ZeroGPT delivers features for text authentication and document checking:

  • DeepAnalyse text detection: Analyzes text inputs to determine the percentage likelihood of AI versus human authorship.
  • Highlighted sentence breakdown: Color-codes detected AI sentences to pinpoint where synthetic text appears in a document.
  • Batch file processing: Upload multiple files simultaneously in PDF, DOCX, and TXT formats for bulk scanning.
  • Integrated plagiarism scanner: Checks scanned text against public web pages and online databases for duplicate content.
  • AI text humanizer tool: Rephrases AI-detected sentences to improve natural reading cadence.
  • Summary & grammar utilities: Built-in text tools for summarizing lengthy articles and checking grammatical errors.
