My Multi-Vault Obsidian Workflow: Practical Strategies for Quick Capture and Organization
Background
Obsidian is a powerful tool for building a “second brain,” capturing fleeting thoughts, and managing your knowledge base. In practice, users can create multiple vaults to separate different types of notes—for example, one vault for ideas and personal tasks, another for references or reading materials, and so on. This approach makes it easier to distinguish what belongs to us from what belongs to others, which is crucial in the slip-box method. Additionally, it helps keep each vault at a manageable size and improves overall performance.
However, the real challenge is ensuring these vaults remain functional and convenient whether you’re on your computer or on your mobile device. How do you capture spontaneous ideas on your phone without syncing thousands of notes? How do you keep your main vault tidy while still allowing quick input of new thoughts from anywhere? Below, we’ll discuss strategies for setting up and managing multiple vaults on different devices.
Key Problems
Sluggish Performance
A “master” vault with tens of thousands of notes can slow down significantly on mobile. This can interfere with quickly capturing an idea in the moment.
Need for Quick Capture
On mobile, we often need to jot down ideas rapidly. A large, plugin-heavy vault might launch too slowly, causing you to miss the chance to record a sudden insight.
Organization and Buffering
Even if we capture ideas on our phone, we still need a systematic way to transfer these notes into a main vault for deeper organization and processing.
Strategies
Use a Separate Mobile Vault
Lightweight Focus: Keep your mobile vault minimal, focusing on capturing new ideas rather than storing everything. This ensures quick startup and eliminates the need to sync huge folders.
Buffer Vault: Let the mobile vault act as a buffer. You can capture ideas on the go, and later decide whether they should move to the main vault or remain as less critical items.
Maintain a Dedicated Secondary Vault on Desktop
Direct Sync: Set up your mobile vault to sync to a secondary vault on your computer. This separation helps you keep your workflow clean.
Selective Transfer: From the secondary vault, decide which notes are truly important or urgent before migrating them into your main vault.
Leverage Soft Links (Symbolic Links)
Use symbolic links on macOS, Windows, or Linux to share only specific folders between your main vault and the secondary Vault. For example:
Daily Notes: If you want daily notes available on both devices, link that folder so entries appear in both vaults.
Templates: You might share templates to maintain consistency in note-taking.
Shopping or Travel Lists: Temporarily move them into the shared folder when you want them on your phone. Later, you can remove these notes from the linked folder to restrict them to one vault.
Automate Note Movement
External Tools: On macOS, set up Hazel rules to monitor a specific folder in your secondary vault. After notes are added to that folder, Hazel will automatically move them to your main vault folder. For other platforms, look for similar tools to achieve this functionality.
Third-Party Plugins: Explore plugins like Vault Transfer that facilitate easy note transfers. When you identify a note that needs organization, you can quickly transfer it with a simple command.
Index Multiple Vaults
Global Search: If you rely on DEVONThink, you can index more than one vault. This lets you search across all vaults simultaneously—no need to open each vault separately to find what you need.
Additional Tools: If DEVONThink isn’t your tool of choice, you can explore solutions like Alfred (macOS), Everything (Windows), or other universal search utilities to index multiple vaults.
Conclusions
When using Obsidian to build your second brain, it pays to be strategic about how you manage vaults across devices. Keep these points in mind:
Separate Mobile Vault: Create a lightweight environment for fast idea capture.
Secondary Desktop Vault: Sync only essential notes from mobile and buffer ideas before transferring them to your main vault.
Soft Links: Share folders (like daily notes or templates) without merging entire vaults.
Automations: Use tools like Hazel or third-party plugins to streamline note transfer.
Global Index: Leverage DEVONThink or other search tools to index multiple vaults for a unified view.
By thoughtfully designing your vault architecture and syncing approach, you’ll ensure that your system remains fast, reliable, and ready to capture your best ideas—anytime, anywhere. This approach keeps your main vault focused on important tasks and resources, while still making space for creativity to flourish in day-to-day life.

I have been exploring the PTKM (Project, Task, and Knowledge Management) system since my doctoral studies, using it to manage various aspects of my work and life for over six years now. PTKM is a system centered around task management, as recording notes, organizing them, and building a knowledge base are all tasks in themselves. After all, everything can be viewed as a task. However, our daily work and life involve more than just building a knowledge base (PKM, second brain); we also need to complete numerous projects and tasks and deliver tangible results. This is why it’s essential to manage projects, tasks, and knowledge systematically and cohesively, and PTKM can help you achieve that.
Feel free to follow me here on Medium and on other platforms to learn more about using PTKM for efficient work and life.
