为 AI 训练、评估与研究提供高质量人类数据
按详细的人口统计、职业和行为条件筛选参与者，触达小众或具代表性的样本，而非泛泛的人群。
采集用于模型微调的人类偏好数据，开展安全性评估与红队测试，并通过反馈 API 把人工环节接入自动化流水线。
注意力检验、诚实度筛查和审批流程，帮助你在分析结果前剔除敷衍或欺诈性回答。
发布研究后能迅速开始收集回答，工具支持筛选条件、配额设定和纵向研究设计。
集学术校对、查重与 AI 写作工具于一体
由认证学术编辑在数小时内审阅论文，返回修订痕迹、批注与说明信。
将文档与大型网页及出版物数据库比对，提交前标出可能缺乏原创性的段落。
识别疑似由大语言模型生成的文本，并提供让 AI 辅助草稿读起来更自然的改写模式。
通过 URL、DOI 或标题检索，生成并核验 APA、MLA、Chicago、AMA、IEEE、ACS 格式的参考文献。
能在网页应用程序中提供更广泛的即时文法与语气修正，但缺乏 Scribbr 深厚的学术专注度与引用格式编排。
提供强大的文句改写与引用工具，但较不着重于全面的学术校对与真人编修。
