手寫筆記、PDF 註記與 AI 學習工具,都在同一塊畫布上

匯入合約、論文或教材,用手直接標註,註記可搜尋並可乾淨匯出。
同時檢索鍵入文字、手寫與速寫,並把筆記轉成摘要、心智圖或結構化計畫。
在共享筆記本、文件和白板上同時協作,不再有版本衝突或反覆傳檔案。
GPTZero is an AI detection platform for identifying machine-generated text. It combines a text detector with a Chrome extension, a plagiarism checker, writing-process verification, and educator-focused classroom tools.
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.
