面向学校与编辑的 AI 检测与写作验证
粘贴文本或上传文档，即可获得整体 AI 概率评分，并逐句标出哪些段落看起来由机器撰写。
可识别 ChatGPT、Gemini、Claude、Llama 等主流模型家族生成的文本，而非只针对单一模型。
Chrome 扩展与 Google Docs 插件把检测带入 Gmail、Docs、Classroom 等你已在使用的界面。
检查内容是否包含来自外部来源的照搬段落，把「是否 AI 生成」与「是否原创」两类问题分开。
面向学术与 SEO 内容的 AI 写作助手
直接在 Google Docs、Office 365 与 LaTeX／Overleaf 中生成和编辑内容，而非另开聊天窗口。
在考虑周围输入的前提下修正语法、拼写、词汇、标点、风格与措辞。
可选 fast、balanced、strong 或 expert 模型，在响应速度与输出深度之间取舍。
产出质量高、结构清晰的文本，力求流畅且具原创性，适合科研与 SEO 场景。
