Rabbithole

Does Your Second Brain Feel Like a Digital Attic?

You’ve spent years capturing ideas, insights, and research. Your knowledge base is a testament to your curiosity, but now it feels… crowded. You know the answer you’re looking for is in there somewhere, but finding it means wading through a sea of unrelated notes. A search for “market analysis” brings up your current project, a startup idea from five years ago, and a book you read in college. The context is lost.

What if you could temporarily silence the noise? What if you could apply a lens to your knowledge base, instantly bringing everything related to a single project into sharp focus and pushing the rest into the background?

That is a Rabbithole.

A Rabbithole is not another folder. It’s a focused, contextual workspace that lets you group related notes without moving them from your central knowledge base. It’s a powerful lens that helps you—and the Spyglass AI—understand your knowledge in a specific context.

The Superpowers You’ll Gain

Using Rabbitholes fundamentally changes how you interact with your knowledge. It moves you from being a digital archivist to a focused thinker.

Find What You Mean, Instantly

When you use the Spyglass search from within a Rabbithole, it operates with laser focus, searching only the notes within that context. This resolves the biggest challenge of a large knowledge base: ambiguity.

End Search Frustration

Imagine you are researching a new computer. You create a “New Computer 2024” Rabbithole and fill it with notes on CPUs, reviews, and budget calculations.

When you search for “performance benchmarks” inside this Rabbithole, Spyglass gives you insights only about your computer research. It won’t be confused by “performance” notes related to your career, a software project, or your fitness goals. Your search becomes instantly more powerful because the context is clear.

Organize Like You Think, Not Like a Filing Cabinet

Traditional folders force you into rigid, permanent decisions. A note can only be in one place, but your ideas are interconnected and multifaceted. Rabbitholes embrace this reality.

Your knowledge can finally be organized based on the context of other similar notes, not a predetermined hierarchy. This is a more natural, fluid way to structure information, especially for complex, long-term projects.

The “Aha!” Moment: A Layer, Not a Box

To truly unlock the power of Rabbitholes, you must understand one crucial concept: a Rabbithole is an organizational layer, not a container.

The Freedom of a Single Knowledge Pool

When you add a note to a Rabbithole, you aren’t moving it or duplicating it. The note still exists in your one-and-only central knowledge base. This means:

• A single note can appear in multiple Rabbitholes.
• You never have to ask “Where should I save this?” again. Just create the note. You can decide how to view it later.
• Your knowledge remains a single, interconnected graph, allowing for unexpected connections to surface outside of any specific context.

This system provides the ultimate flexibility. You get the focused, distraction-free environment of a dedicated workspace, without ever fracturing your knowledge base.

Building Your Focused Workspace

Curating a Rabbithole is effortless:

• Create on the Fly: While inside a Rabbithole, any new note you create is automatically associated with it (while still living in your main knowledge base).
• Add from Anywhere: Search your entire knowledge base from within a Rabbithole and add any existing note with a single click.
• Drag-and-Drop Discovery: The sidebar intelligently suggests other notes from your knowledge base that are related to your current Rabbithole. Simply drag them in.

By removing the friction of organization, Rabbitholes empower you to spend more time thinking and less time managing files. This is a fundamental shift in personal knowledge management, transforming your second brain from a passive repository into an active partner in your thinking process.
