通过可配置写作环境记录全过程，区分真人打字与AI生成
Humanly: A Configurable and Traceable Environment for Human-AI Collaborative Writing
- 构建可定制写作环境，全程记录操作与AI辅助行为
- 生成带配置信息的防篡改写作证书，支持异常行为分析
- 适用于作业提交、审稿和自我认证，能有效识别真人打字
教师、会议主席和公众读者都只能基于最终文档判断写作质量，无法了解其生成过程。仅凭终稿无法判断文档是人工输入、AI生成还是人机协作完成。现有过程追踪工具多依赖文档历史，记录粗糙，且对写作环境控制有限。Humanly 是一个以写作过程本身为证据的平台：用户可为个人文档或任务配置写作环境，在记录操作与平台内AI辅助的环境中进行撰写。完成会话后，系统可打包生成带配置感知的防篡改写作证书，并支持异常行为审查。该平台适用于课程作业、同行评审和个人认证等场景。用户研究表明，Humanly 在各类角色中均有实用价值；红队测试表明，Humanly Typing Detector 能有效区分真人打字与自动化输入。
原文摘要 · Abstract (English)
Teachers, conference chairs, and public readers all judge writing from limited evidence, seeing only a finished document and not the process that produced it. Final text alone cannot reveal whether a document was produced through human typing, AI generation, or mixed human-AI collaboration. Existing process-tracking tools help, but many are tied to host-document histories, provide coarse activity records, and offer limited control over the writing environment. Humanly is a writing platform that makes the writing process itself the evidence. Users configure writing environments for personal documents or assigned tasks and draft in a workspace that records writing activity and in-platform AI assistance. Humanly can package a completed session into a sealed writing certificate with configuration-aware anomaly behavior review. It can support writing scenarios such as course assignments, peer review, and personal certification. Our user study shows that Humanly is helpful across roles, and a red-teaming study shows that the Humanly Typing Detector distinguishes human hand typing from automated typing.
