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。
把零散资料变成可建构世界观的视觉化知识库
把 PDF、网页、YouTube 视频、播客以及 Readwise、Zotero 条目拆成卡片，并顺着每条引文深入阅读。
把任意目标转化为个性化课程，并借助 AI 处理阅读材料，再在白板上组织想法。
用嵌套标签与属性为知识建立可随学习演化而重构的结构，而不是扁平的文件夹。
通过插件、MCP 服务器与 CLI，从 Claude Code、ChatGPT、Codex 或 Grok Bot 查询你的知识库。
