Your thoughts are not folders. They are a living neural constellation.
Break out of rigid file hierarchies. Synapse connects your ideas the way your mind naturally works—through bi-directional links, dynamic knowledge graphs, and local-first encrypted markdown.
Zettelkasten Method
Atomized note units connected by strict bi-directional references.
"Each slip-note contains one idea. Knowledge accumulates organically as cross-references multiply over decades."
Direct Synaptic Links (4)
Built on First Principles of Cognition
Most note apps force you into nesting folders that collapse under their own weight. Synapse lets knowledge weave together like real biological memory.
Bi-Directional Backlinks
Type [[Idea]] anywhere. Synapse establishes two-way synaptic references with unlinked mention detection, ensuring no thought is ever lost in isolation.
100% Local-First Markdown
Your notes are plain text files on your own filesystem. No proprietary databases, no vendor lock-in. If Synapse disappeared tomorrow, your life's thoughts remain readable in any text editor.
SQL & Dataview Query Blocks
Query your vault like an analytical database. Run real-time queries inside any note to dynamically aggregate projects, pending decisions, or reading backlogs.
Write freely. Let the graph weave connections in the background.
As you type, Synapse parses semantic references, suggests existing nodes, and flags serendipitous links to notes you wrote months ago.

# The Convexity of Note Architecture
Most knowledge repositories suffer from [[Hierarchical Rot]]. When you categorize by rigid topic directories, your notes become fragile.
Instead, through [[Associative Indexing]] and [[Zettelkasten Method]], every additional note increases the value of the network exponentially.
