这不是一款事项待办和时间管理的工具，也不是一个日记甚至带有双向链接的笔记类应用，虽然内置了记忆力训练的功能，但是还不敢比肩强大的 Anki 卡组…… 这是一个可以安静跟自己对话的 App 、可以反复打磨自己想法的空间，按照大纲式对话的样子把跨时间的思维组织在一起的瞬间。 那我可以用这个应用做什么？ - 记录、采摘、拍照、留音、写作…… - 导入微信读书、Kindle 上的读书笔记； - 观察自己的碎碎念头； - 甚至记录自己的财务规划； - 思考最好的工具之一是写作 - 使用一种大纲对话体进行记录和写作 - 在意犹未尽之处留下记忆的面包屑，我们不妨叫他 [[兔子洞]] - 假想着跟头脑中的另一个小人喃喃对话 - 或者在大语言模型的加持下，跟AI进行对话 - 在灯火阑珊的街尾，完成自我陪伴、自我进化、自我构建！
