GPTZero — Preserve what's human
GPTZero is a commercial AI-detection platform designed to identify AI-generated text (from models such as ChatGPT, GPT-4/5, Gemini, Claude, LLaMA and others) and provide interpretable, sentence-level analysis, writing feedback, and plagiarism detection. It combines a multi-component detection model with integrations and tooling suited for educators, enterprises, publishers, and recruiters.
Key technical features
- Multi-component detection model: a 7-part pipeline analyzing hundreds of features (perplexity, burstiness, style, sentence-level signals) to minimize false positives and improve cross-model generalization.
- Sentence-level and phrase highlights: color-coded identification of likely AI-generated spans for precise review and interpretability.
- Advanced AI Scan: high-accuracy, model-aware classification tuned on modern LLM outputs (GPT4.x, Gemini variants, Claude, etc.).
- Plagiarism & source-finding: integrated online-source scanning to surface unattributed matches and verify citations.
- Writing feedback & grammar: automated grammar corrections and writing improvement suggestions to help users refine text and reduce AI-like artifacts.
- Multilingual support: full support for English, German, Portuguese, French, and Spanish with industry-leading accuracy; model also used internationally across 100+ countries.
- Integrations & deployment: Chrome extension, Google Docs add-on, LMS integrations (Canvas, Moodle, Google Classroom), Zapier, and an API for enterprise embedding.
- Enterprise features: bulk scanning, file uploads, page-by-page scanning, enhanced security, and reporting suitable for institutions and corporations.
Primary use cases
- Educators & institutions: detect AI use in essays and assignments, monitor AI adoption across classes, and support academic integrity programs.
- Students & writers: verify originality, get grammar/writing feedback, and avoid misattribution or false accusations through transparency tools.
- Recruiters & hiring teams: screen writing samples to ensure candidate authenticity during evaluation.
- Publishers & legal teams: verify authorship, check for unattributed content, and support editorial due diligence.
- Developers & enterprises: integrate detection into products and workflows via API, Chrome extension, and LMS connectors.
Unique selling points
- High reported accuracy (claims of ~99% on certain datasets) and strong performance on mixed human/AI documents.
- Interpretability: clear sentence-level explanations of why text was flagged as AI-generated.
- Broad integrations and enterprise-ready features (security, bulk scanning, reporting).
Recommended technical workflow
- Ingest text or upload documents (supports large documents; longer inputs yield stronger accuracy).
- Run Advanced Scan for model-aware analysis and sentence-level highlights.
- Use plagiarism/source finder to verify citations and check for unattributed matches.
- Optionally run grammar/writing feedback to improve authenticity and reduce AI-like patterns.
- Export reports or integrate via API for automated pipelines and institutional monitoring.
