Zettly

Local-first desktop workspace

One vault for notes, canvas, decks, tasks, and AI.

Zettly keeps notes, boards, decks, calendar, and tasks in one folder on your machine — write in Markdown once; wikilinks and AI stay tied to what you linked.

Zettly comes from Zettelkasten — Luhmann’s linked-note method: atomic notes, woven together. Why the name

The fracture

Five apps. Zero connection.

Notes, tasks, calendar, slides, and AI each live in their own app — nothing shares the same files.

The fracture

Every switch rebuilds context.

You copy links, re-open tabs, and re-explain the same idea — because nothing stays in sync.

The fracture

Your work is scattered across landlords.

Every app owns a slice of your thinking — and none of them share the same files on your machine.

The fracture

Productivity became a wall of tabs .

Notes, tasks, calendar, slides, and AI each live in their own app — every switch rebuilds context, and nothing stays in sync.

Liberation meadow at dawn — chains falling away, a laptop and vault folder glowing in the corner, symbolic keys and sail-pages in the sky, a chain-fortress dissolving on the horizon

The alternative

Think freely. Build on your machine.

Not another cloud landlord. A private vault folder where notes, boards, graph, and AI stay connected — because they share the same files.

  1. Write

    Markdown in a folder you control — plain text, yours forever.

  2. Open anywhere

    Notes, graph, boards, decks, tasks — one vault, edit once.

Proof

One vault, five surfaces.

A sword-laptop on your desk parries a surreal landlord symbol in a symbolic sky while your files glow inside — you hold the brass key, your data stays local
