1. Note-Taking Approach
容量： You create notes as objects, such as people, books, and meetings. This object model builds structured content and links notes without folders. It feels less rigid and more organic.
黑曜石： You write atomic notes in markdown, then join them with links. Internal linking connects vault notes into a web of relevant information. It rewards users who like plain files and full control.
2. AI Assistant & AI Tools
容量： The ai assistant is built in and ready on day one. It can brainstorm ideas, draft text, and answer ai questions from your knowledge base. No API key or config is needed.
黑曜石： Obsidian AI comes from ai powered plugins like Copilot and a text generator. These use language models such as ChatGPT, or you can run a local llm. This gives context aware answers with retrieval augmented generation across the entire vault.
⚠️ 警告： Obsidian’s AI is more flexible but needs setup. You must install plug ins and, in some cases, pay for a language model.
3. Hidden Connections
容量： Contextual backlinking shows how objects relate as you write. This surfaces hidden connections and helps new ideas appear on their own.
黑曜石： The visual graph maps every link as a living mind map. Smart connections uses semantic similarity, not keywords, to link ideas across different vaults.
4. Powerful Search
容量： A powerful search find bar scans every page, tag, and object type. Results appear fast, which keeps quick capture and review smooth.
黑曜石： Search covers your whole vault and pairs with a canvas workspace for visual planning. AI plugins add semantic search over obsidian notes for deeper research.

容量： Custom object types let you model tasks, projects, and people your way. Templates and tags keep structured content tidy without heavy config.
黑曜石： Custom themes, dark mode, and powered templates reshape the app. Global settings profiles and various global settings profiles suit users who love to tinker.
7. Offline Access & Devices
容量： A desktop app, web app, and mobile app keep notes in sync across devices. Templating and offline edits keep you working with no internet.
黑曜石： Obsidian runs offline by default since files live on your device. Sync is a paid add-on when you want notes on android and other devices.
8. 定价与成本
让我们来并排比较一下这些定价方案。
| 计划 | 容量 | 黑曜石 |
|---|---|---|

| 入场费 | Pro $9.99/month | Sync $4/month |
| 更高层级 | Believer $12.49/month | Publish $8/month |

容量： One monthly price unlocks AI features, daily notes, and full sync. It is simple to plan around for a single month or a year.
