Mycelium
FeaturesPhilosophy

Second brain, naturally

Thoughts that branch, connect, and grow.

Mycelium is note-taking modeled on how minds actually work — networked, associative, alive. Capture once. Rediscover forever.

Bi-directional links

Ideas find each other. Every note becomes a node in a living map of thought.

Emergent structure

No folders required. Patterns surface from how you actually think.

Recall by context

Surface the right memory at the right moment — not by search alone.

“The best second brain doesn't organize your thoughts — it remembers how they connect.”

— The Mycelium Manifesto
