手写笔记、PDF 批注与 AI 学习工具,都在同一块画布上
低延迟墨迹、防误触手掌识别、划掉即擦除以及手写转文字,让书写接近纸笔手感。
导入合同、论文或教材,用手直接标注,批注可搜索并可干净导出。
同时检索键入文本、手写与速写,并把笔记转成摘要、思维导图或结构化计划。
在共享笔记本、文档和白板上同时协作,不再有版本冲突或反复传文件。
替你打理业务的智能体商业操作系统
用自然语言描述目标——催收欠款、跑薪资、策划促销——AI 智能体直接在已连接的模块中执行,而不是等你点击。
通过 WhatsApp 或邮件发送发票、礼貌催收、款项到账即自动入账,并让会计与利润现金报告保持最新且易读。
覆盖从招聘到发薪的全流程,并以可读摘要而非表格的形式呈现经营数据。
描述你的业务即可生成带商品与价格的站点,随后由智能体按计划撰写并发布社媒内容,发布前可设审批关。
