English Version Introduction

• 纯本地、Markdown 格式的思维导图，AI 可直接读写，修改。
• 设计理念源自「28 笔记法」，可一键聚焦重点 / 隐藏非重点。
• 简洁，优雅，易用。

🧤 如何安装

1. 打开 Obsidian 桌面端，进入设置 → 第三方插件 → 社区插件
2. 搜索 28 Notes MindMap，安装并启用

🪴 Key Features

❶ 简洁易用

• 简洁易用：没有复杂的功能，繁复的界面，如同白纸一般简单；操作方式对齐常规思维导图软件，让你没有任何切换成本，轻松即可上手，思维飞扬。
• Obsidian 编辑器：在 Obsidian 中央编辑器直接编辑，无需另开渲染窗口，所见即所得。

图注：简单、干净的使用体验

❷ AI 友好

大多数思维导图软件，把数据存在私有格式里， 导致 AI Agent 工具难以直接阅读和更改。

而 28 Notes MindMap 从设计之初，就为了 AI 易用：

• 纯 Markdown 存储：你的导图就是一个普通 .md 本地文件，内容是纯粹的大纲形式。关掉插件、甚至不用 Obsidian，用任何文本编辑器都能读写。
• 为 Agent 编辑设计：支持 Agent 定位到指定节点树编辑；支持在思维导图内添加 AI 编辑规则，约束 AI 更改；AI 更改后会自动添加 AI 标记，便于区分。
• 预埋 AI 指令：内置 AI 编辑规则，AI 编辑时会自动遵循。你只需专注需求，而无需关心格式。

❸ 聚焦重点

思维导图最大的痛点就是节点变多后， 一打开密密麻麻，难以使用。

28 Notes MindMap 设计了大量的创新模式，以解决这个问题：

• 关注点分离功能：支持将节点标记为当前关注 / 次要节点，并一键只显示当前关注节点 / 隐藏次要节点，瞬间聚焦重点。
• 下钻与捷径功能：支持一键下钻进某个节点树，聚焦单树。并能将此下钻视图存为捷径，下次打开直接进入。上次思维漫游到哪里，这次直接看哪里。
• 按层级折叠功能：支持一键折叠 / 打开至某一层级。瞬间从迷失到清晰。

❹ 为知识管理设计

思维导图通常用于学习和思维扩展， 而 28 Notes Mind Map 在此之上，专门针对知识管理做了焕然一新的创新。

• 基础功能：高度集成 Obsidian；性能专门优化，20 万字超大型思维导图加载仅需 2S；支持创新的文档管理功能，让思维导图嵌入传统文档管理流程中。
• 基于知识管理的结构设计：基于知识从混乱到结构化的过程，设计严格树状层级结构；不含连线、概要等功能，有利于知识压缩，也避免结构交织混乱，使得思维导图可以扩展到数十万量级。
• 支持 inl 结构：你可以将一个领域的笔记 / 文件全部存到一个思维导图里，并生成临时使用捷径。使用上，形成 Library 和 Now 注意力分离机制；管理上，让知识的存放和使用归为一处，形成最佳管理状态。

28 Notes MindMap — 极简，无混乱，AI 友好

English Documentation

28 Notes MindMap

• Markdown-based mind maps that AI can read, write, and edit directly.
• Design inspired by the "28 Notes Method", with one-click focus on key points / hiding of non-essentials.
• Simple, elegant, and easy to use.

🧤 Installation

1. Open Obsidian desktop, go to Settings → Third-party plugins → Community plugins.
2. Search for 28 Notes MindMap, install and enable it.

🪴 Key Features

❶ Simple & Easy to Use

• Simple & easy to use: No complex features or cluttered UI — as plain as a blank sheet of paper. The interaction aligns with conventional mind-map software, so you can pick it up with zero switching cost and let your thoughts flow.
• Obsidian editor: Edit directly in Obsidian's central editor, no separate render window needed — what you see is what you get.

Caption: A simple and clean user experience

❷ AI-Friendly

Most mind-map software stores data in proprietary formats, making it hard for AI Agent tools to read or modify directly.

28 Notes MindMap was designed from the ground up to be AI-friendly:

• Pure Markdown storage: Your map is just a plain local .md file in outline form. Close the plugin, or even skip Obsidian entirely — any text editor can read it.
• Built for Agent editing: An Agent can target a specific node tree and edit just that one; you can add AI editing rules inside the map to constrain the AI; AI-made changes are marked automatically, so you can tell them apart at a glance.
• AI instructions built in: The built-in AI editing rules are followed automatically whenever an AI edits. You only focus on your needs, never on the format.

❸ Focus on What Matters

The biggest pain point of mind maps is that once nodes grow, opening one feels overwhelming and unusable.

28 Notes MindMap introduces many innovative modes to solve this:

• Focus separation: Mark the node you're focused on as Now and secondary nodes as Minor, then show only Now / hide Minor with one click — instantly zero in on what matters.
• Drill in & shortcuts: Drill into a node tree with one click to focus on that single tree, and save that view as a shortcut to reopen it directly next time — pick up exactly where your mind left off.
• Fold by level: Fold / unfold to any level with one click — instantly go from lost to clear.

❹ Optimized for Knowledge Management

Mind maps are usually used for learning and expanding thoughts. On top of that, 28 Notes Mind Map brings a fresh set of innovations built specifically for knowledge management.

• Core features: Deeply integrated with Obsidian; performance specifically optimized — a 200,000-character map loads in about 2 seconds; innovative document management lets mind maps fit into a conventional document workflow.
• A structure designed for knowledge management: Built around the path from messy to structured knowledge — a strict tree hierarchy, with no connectors or summary frames. That keeps knowledge compressed and avoids structural entanglement, so a map can scale to hundreds of thousands of nodes.
• Supports the "inl" structure: Store all the notes / files of one domain in a single mind map, and spin off a temporary shortcut for daily use. In use, this gives you a Library / Now separation of attention; in management, knowledge is stored and used in one place — the best possible state.

🚀 Quick Start

Create your first map

• Click the "28 Notes" icon in the left ribbon.
• Or open the command palette, search "28", and use the command / hotkey to create one quickly.

Basic shortcuts

Note: Cmd is Ctrl on Windows, Option is Alt; keys marked * are not customizable, all others are; \ means no default shortcut, but you can set one.

💰 Trial & Pricing

14-day free trial

A full-feature 14-day trial starts automatically after install, with no limitations.

After the trial

We use a special pricing model:

• Most features found in mainstream mind-map software: unlimited
  • e.g. unlimited map generation, images, notes, Obsidian links, local file links, node links, etc.
• 28 Notes' original innovations: require activation after the trial
  • e.g. Now, Minor, shortcuts, AI location path, multi-level folding, etc.

Details:

Pricing

• Early-bird price ¥48 (original ¥96 → -50%)
• One-time purchase: buy once, use local features forever
• Supports activation on 3 devices
• Payment & activation: after installing the plugin, see Obsidian → Settings → 28 Notes → License

Note: The one-time purchase covers all local features, but excludes possible future online AI-generation services / server-dependent features (noted for clarity only; such features are unlikely, since current AI Agents are already simple and easy to use).

❓ FAQ

Will my data be uploaded?

No. 28 Notes runs fully locally — no data collection, no external API calls.

How is it different from other mind-map software / plugins?

• Other mind-map software / plugins: proprietary formats that AI cannot edit directly; features converge.
• 28 Notes: Markdown format, suited for AI Agents; packed with original features.

Mobile support?

Desktop only for now. Mobile may come, but there is no fixed timeline.

Can the activation code move to another computer?

Yes. One code activates up to 3 devices at the same time. Deactivate on the old device to use it on the new one.

Can I let AI edit the map file directly?

Yes! That's exactly the design goal. Select a node, right-click "Copy AI location path", hand it to the Agent, and it can pinpoint and edit precisely. You don't even need to tell the AI what format to follow or add any Skill wrapper — 28 Notes has already taken care of it.
