A digital garden for your thoughts

Plant a note.
Grow a mind.

Most apps store notes like boxes in an attic. Cortex tends them like a garden — seedlings caught in passing, grafted and pruned, until a few become evergreen.

Growth stages

The three ages of a note

Plate I — fleeting note

Seedling

“idea: what if meetings had trailers?”

Caught in passing. Five seconds, one keystroke, no pressure to finish it. Most seedlings stay small — and that is fine.

Plate II — developing note

Budding

“attention residue — linked to thesis ch. 3, deep work”

Grafted to its neighbors. Links form, sources attach, the idea thickens. Cortex shows you every connection.

Plate III — permanent note

Evergreen

“essay: why I quit the feed — 14 sources, revised 9 times”

Dense and permanent. Evergreen notes are the ones you build on — and the ones Cortex never lets you lose.

Tending

A garden keeps itself, with a little help.

Grafting

Links, not folders

Graft one note onto another with a link, and both grow new branches. Backlinks show every graft ever made.

Seasons

A weekly tending pass

Cortex surfaces what needs water — or pruning — on a gentle schedule. You review; the garden stays young.

Native soil

Local-first roots

Your garden grows on your ground: plain Markdown files, encrypted when they sync, readable anywhere.

Harvest

Pick anything, any season

Export a single note or whole beds whenever you like. Your words travel — no lock-in, no frost damage.

“My notes used to be where ideas went to die. Now they're where they go to grow.”
