AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.

Monthly, reproducible rankings of AI humanizers tested against six AI detectors
Leading AI humanizers are scored against GPTZero, ZeroGPT, Copyleaks, Winston AI, Originality.ai and Pangram using identical prompts every cycle.
The overall figure blends bypass rate, meaning preservation, readability and consistency, with explicit deductions for failures like unchanged output or meaning drift.
Prompts span academic essays, application essays, blog posts, business email, marketing copy, discussion boards and news articles to expose uneven performance.
Every prompt, raw output and detector verdict is published with the scoring script, a JSON endpoint and a GitHub repo.
