Build a second brain you can still find your way around
SpacebarX turns notes, projects, ideas and resources into one private tree. Capture quickly, organise when it matters, and find what you need without rebuilding your system every year.
The dotted markers are one item, shown twice. Not a copy in each place.
Keep ideas connected by structure, not maintenance
Use one inbox for capture, then move items into projects, areas, resources and archive branches. The hierarchy remains visible, search stays fast, and mirrors let one idea appear in more than one place.
Capture without deciding
Get the thought down, then put it where it belongs later.
Find it again
Search across the whole outline or save the searches you return to.
Keep it private
The original workspace stays on your device, with optional sync through your own cloud.
Start with four branches
Create an Inbox, then Projects, Areas, Resources and Archive
Five headings hold everything. The Inbox is the front door; the other four are where things live once you know what they are.
Put every new note in Inbox first
Deciding where something belongs is a different job from writing it down, and doing both at once is why capture stops happening.
Move it when its context is clear, archive it when it is not active
An idea that belongs in two places becomes a mirror rather than a second copy, so the two can never disagree.
