AI Thinks With You, Never For You

AI 只辅助思考,从不替你下结论

AI 只輔助思考,從不替你下結論

Every AI feature in Jotaid stops short of a conclusion. It handles the groundwork — surfacing nodes, structuring, connecting — but the real thinking is yours.

Jotaid 的每一个 AI 功能都止步于结论之前,只负责挖掘节点、梳理结构、串联关联等基本操作,真正判断来自你的思考

Jotaid 的每一個 AI 功能都止步於結論之前,只負責挖掘節點、梳理結構、串聯關聯等基本操作,真正的判斷來自你的思考

  • Node Suggestions: AI picks out concepts worth turning into nodes, with the notes that link them — you decide whether to make it official.

    节点建议:AI 在笔记中挑出值得成为节点的概念,连同关联笔记,你判断决定是否建立相关关联

    節點建議:AI 從筆記中找出值得成為節點的概念,並列出相關筆記,由你決定是否建立連結

  • Potential Relations: AI doesn't just explain notes that already overlap — it finds concept pairs you've never linked, and reasons out why they might matter.

    潜在关系:AI 不止解读已共现的笔记,还会找出从未关联过的概念对,推理出它们为何可能相关

    潛在關係:AI 不止解讀已共現的筆記,還會找出從未關聯過的概念對,推理出它們為何可能相關

  • Theme Summaries: AI reads every note in a Theme — not just the highlights, but a spark you might not have put into words yourself.

    主题总结:AI 读取主题下所有笔记,不止总结要点,还会收敛成一句你可能都未必说得出的启发

    主題摘要:AI 讀取主題下所有筆記,不止總結要點,還會收斂成一句你可能都未必說得出的啟發

See the Connections, Not Just the Notes

捕捉概念关联,而不只是笔记本身

捕捉概念關聯,而不只是筆記本身

A Jotaid node is a concept, not a whole note — finer-grained than a typical note graph. A co-occurrence matrix quantifies and clusters those relationships, often more revealing than the notes themselves.

Jotaid 节点是有独立含义的概念,而非整篇笔记。颗粒度比常见笔记图谱更细。关系量化、聚类的共现矩阵格外有启发性

Jotaid 節點是有獨立含義的概念,而非整篇筆記。粒度比常見筆記圖譜更細。關係量化、分群的共現矩陣格外有啟發性

  • Scored Connections: Every link is scored by similarity, every node sorted into one of three roles by how it clusters — no more guessing what matters.

    连接分级:连接以相似度打分,节点按聚类特征分为三类,再也不用依靠直觉猜测哪个关联重要

    連結分級:依相似度為連結評分,節點按分群特徵分為三類,再也不用依靠直覺猜測哪個關聯重要

  • Co-occurrence Matrix: Maps how often concept nodes appear together, then clusters them into groups you never tagged by hand.

    共现矩阵:呈现概念节点同时出现的频率,通过层次聚类自动归组,这些分组你从未手动标记过

    共現矩陣:呈現概念節點同時出現的頻率,透過階層式分群自動分組,這些分組你從未手動標記過

  • Card Relations: Every note is a card on an infinite canvas — drag them around and the relationships between them get sharper, more concrete.

    卡片关系:每篇笔记都是无限画布上的卡片,笔记之间的主题关系在拖拽操控中会更加具象清晰

    卡片關係:每篇筆記都是無限畫布上的卡片,筆記之間的主題關係在拖曳操控中會更加具象清晰

Flexes to the Method You Already Use

灵活实现你熟悉偏好的笔记方法论

靈活運用你熟悉的筆記方法

Jotaid doesn't impose a system. Slip-box, PARA, design thinking — whatever you use, the structure is native here, no workarounds needed.

Jotaid 不强加任何方法论,无论卡片记录法、PARA,还是设计思维,都能在这里找到原生的组织结构,不必绕弯路迁就

Jotaid 不強加任何方法論,無論卡片記錄法、PARA,還是設計思維,都能在這裡找到原生的組織結構,不必繞彎路遷就

  • Zettelkasten: Fleeting and literature notes default into the Inbox — turn any note into a Project and it becomes a permanent Zettelkasten slip-box.

    卡片盒笔记:闪念与文献笔记默认存入 Inbox 卡片盒;新建一个项目可作为永久笔记卡片盒

    卡片盒筆記:閃念與文獻筆記預設存入 Inbox 卡片盒;新增一個專案可作為永久筆記卡片盒

  • Second Brain: Structure Projects however PARA calls for, and run CODE's full workflow — capture straight through to expression.

    第二大脑:按 PARA 思路任意创建项目结构,实现 CODE 的笔记从捕捉到表达的知识管理流程

    第二大腦:按 PARA 思路任意建立專案結構,實現 CODE 的筆記從捕捉到表達的知識管理流程

  • Design Thinking: Capture freely on an infinite canvas, then organize into Themes — the Double Diamond's diverge-then-converge process, built in.

    设计思维:无限画布上自由记录,组织笔记创建主题;实现从发散到收敛的双钻问题思考与创新

    設計思維:無限畫布上自由記錄,組織筆記建立主題;實現從發散到收斂的雙鑽問題思考與創新

Pain: Hundreds of papers, endless highlights — still no thread connects them.

痛点:读了上百篇,划了上百段,却没有一条线索能把它们串起来

痛點:讀了上百篇,劃了上百段,卻沒有一條線索能把它們串起來

Fix: Concept nodes turn your notes into a living graph. See which ideas cluster and which stand alone — connections buried across sources surface instantly.

解决:概念节点串联笔记,构成知识图谱的具象关系网,一眼看清哪些主题关系紧密、哪些还是孤岛,让淹没在数百篇里的关系脉络浮现

解決:概念節點串聯筆記,構成知識圖譜的具象關係網,一眼看清哪些主題關係緊密、哪些還是孤島,讓淹沒在數百篇裡的關係脈絡浮現

Pain: Information isn't the problem — a clear, actionable read on it is.

痛点:从不缺信息,缺的是从散落碎片看出那个能据以行动的判断

痛點:從不缺資訊,缺的是從零散線索中形成能付諸行動的判斷

Fix: The co-occurrence matrix tracks how often concepts appear together, surfacing links search can't find and you never drew. Patterns emerge on their own.

解决:共现矩阵统计概念节点在笔记里同时出现的频次,把搜索找不到、你从没主动链接的关联呈现出来,让信息里散落的模式清晰可见

解決:共現矩陣統計概念節點在筆記裡同時出現的頻次,把搜尋找不到、你從沒主動連結的關聯呈現出來,讓散落在資訊中的規律清晰可見

Pain: Plugins, configs, constant upkeep — the writing always comes last.

痛点:插件、配置、维护,还没写就折腾一番,写字反倒成了其次

痛點:外掛、設定、維護,還沒開始寫,就得先忙著調整,寫作反而成了次要的事

Fix: A native Markdown editor with live highlighting, split preview, and three built-in themes. No plugins, no setup — just open it and write.

解决:原生Markdown编辑器,实时语法高亮、分离式预览、三款设计主题(浅色、暖纸、深色)全内置,不折腾插件或配置,打开就写

Pain: You read, you highlight, notes pile up — more clutter, never a system.

痛点:边读边划,高亮和笔记越攒越多,认知越来越乱,难成体系

痛點:邊讀邊劃,畫線和筆記越積越多,想法卻越來越亂,難以整理成系統

Fix: Every note is a card on an infinite canvas. Drag fragments into place and watch them settle into themes — until it becomes a knowledge system that's yours alone.

解决:笔记真的可以是卡片,无限画布任意拖拽,碎片组织提炼成主题,再零散想法也可以瞬间激发灵感,长成一套只属于你的知识体系

解決:筆記真的可以是卡片,無限畫布任意拖曳,碎片組織提煉成主題,再零散想法也可以瞬間激發靈感,長成一套只屬於你的知識體系
