本地优先的无限画布视觉笔记，集思维导图与知识库 AI 于一体
在画布上任意摆放卡片，再切换思维导图或数据库视图查看结构，无需重排笔记。
在画布上高亮、批注 PDF，并对视频做时间戳笔记；高亮会自动变成参考卡片。
语义搜索、知识库问答与内容检索帮你找到对的笔记；聊天可使用你自己的模型 API 密钥。
文件默认保存在设备上，可通过 WebDAV、S3、OneDrive 或百度网盘跨设备同步，凭据由你掌握。
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。
