Desk lamp, index cards, and a teal cup in a dark study

Every note knows its neighbors.

Backlinks, a daily page, and a graph you can read at the end of the night.

Start writingSee a sample

A link is a sentence, not a tag.

Point at the line that matters. Halden keeps that line attached when the source moves.

12 March

Salt and the night train

The dock master said the salt smell arrives before the engine. Keep this next to the line about attention.

Four stops on the map.

Backlink

The page that mentioned this one is one click away.

Daily page

Today starts empty. Loose ends from yesterday sit at the top.

Index cards connected by teal thread on a black table

Source

A clipped paragraph stays attached to the claim you wrote.

Graph

See which notes share a source, without a second window.

“I can see which interview a paragraph came from without opening a second app.”
