These are the questions we get asked the most about us.
GPTZero is one of the most widely used AI content detection tools, specifically designed to identify whether a piece of text was written by a human or generated by AI models like ChatGPT, GPT-4, Google Gemini, Claude, and others. It was originally developed to help educators detect AI-written assignments but has expanded its use to publishers, businesses, and government institutions. GPTZero sets the standard for responsible AI use by promoting transparency and content authenticity.
AI Content Detection: Accurately identifies AI-generated text, including content from major LLMs like GPT-4, Gemini, and Claude.
Origin Scoring System: Assigns a “Human Likelihood” score to evaluate how likely the text was written by a human.
Sentence-Level Highlighting: Highlights AI-written portions within the text, helping users understand which parts are likely machine-generated.
Batch File Scanning: Upload multiple files (PDFs, DOCX, TXT) to check for AI usage across large datasets.
API Access: Provides API integration for educational institutions, businesses, and LMS platforms.
Enterprise Dashboard: Centralized analytics and user management tools for large organizations and teams.
Educators & Schools (to detect AI in student work)
Publishers & Editors (to verify authenticity of content)
Businesses & Legal Teams (for content compliance and IP protection)
Government & Research Bodies (to prevent misuse of generative AI)
Freelance Clients (to validate writer submissions)
1. Academic Integrity Checks: Detecting AI-generated essays and research submissions in educational settings. 2. Content Authenticity Verification: Verifying if submitted content for publication or SEO is written by a human. 3. Enterprise Content Review: Ensuring company documentation, proposals, or policies are authentically human-written. 4. Freelance Quality Control: Confirming originality in articles, reports, and blogs received from freelancers. 5. Government or Legal Content Auditing: Screening public-facing materials or legal documents for AI involvement.
Free Plan: Basic detection with limited daily usage and file size.
Pro Plan: Starting at $10/month, includes higher daily limits, detailed reports, and sentence-level analysis.
Educator Plan: Tailored pricing for schools, includes classroom dashboard, batch uploads, and student management tools.
Enterprise/Custom API: Custom pricing for publishers, legal teams, and institutions needing bulk scanning and integrations.
GPTZero is known for its transparency, sentence-level analysis, and educational focus, making it more suitable for schools and institutions than tools like ZeroGPT. Winston AI may be more accurate in some enterprise use cases, but GPTZero is more user-friendly and widely adopted.
