Notes that find each other.
Cairn is a local-first second brain for people who capture thoughts and need them back.
Works with
Link a note. The other side links back.
Bidirectional links turn a pile of files into a map. Follow a thread from a meeting into last winter's research without hunting folders.
Inbox in one keystroke
Dump a thought before it evaporates. Sort later. Cairn never asks you to file first.
Search that forgives
Half a phrase, a date, a person. Recalled notes surface even when the title was terrible.
Files on your machine
Plain Markdown in a folder you already back up. Leave whenever you want. Nothing is trapped.

Capture, then keep going
Capture
A daily page is waiting. Type, paste, or drop a file. No schema, no board to groom.
Recall
Links, backlinks, and search sit behind the writing. The graph is there when you want it, not before.
