Relation Sync is a powerful Obsidian plugin that automates the management of bidirectional relationships within your vault's YAML frontmatter. Stop manually updating back-references; define your logic once and let the plugin handle the rest.
- 🔄 Automatic Bidirectional Syncing: Add a relation in one note, and the inverse is instantly added to the target note.
- 📚 Extensive Default Library: Over 50+ pre-configured relation pairs covering Family, Romantic, Professional, and Creative relationships.
- 🌍 Multi-Language Support: Fully localized in 8 languages (English, Italian, German, Spanish, French, Japanese, Portuguese, and Chinese).
- 🛠️ Fully Customizable: Define your own custom relation pairs (e.g.,
Villain↔Hero,Master↔Apprentice). - 📂 Multi-Value Aware: Handles both single links and arrays of links seamlessly.
- ⚡ Bulk Sync Tool: A specialized tool to scan and synchronize your entire vault in one click.
- 🎨 Modern Settings UI: Grouped, searchable, and filterable interface for effortless configuration.
Imagine you are writing about your family. You add a link to your father in your note:
John Doe.md:
---
father: [[David Doe]]
---Relation Sync will immediately detect this and update David's note:
David Doe.md:
---
child: [[John Doe]]
---If you later change or remove the link, the plugin updates the corresponding inverse relation automatically, ensuring your graph remains perfectly consistent.
