Aetherboard · local whiteboard
A private, offline whiteboard your AI can draw on.

Designed like a real tool
Less software between you and the thought.
The canvas glides under the hand. Marker strokes borrow their softness from Japanese calligraphy. Polaroids land with a quiet shutter, the laser pointer fades elegantly while you share your screen, and useful hotkeys keep the interface nearly invisible.
There are fewer features on purpose. No multiplayer dashboard. No account needed to open your own boards. No subscription keeping your thinking behind a renewal.
Fast enough for the moment
Open a board, put the thought somewhere, move the work forward. Search is there when you return.
Private by default
Your board content stays on your computer unless you decide to move or share it.
Own the whole thing
Pay once for Mac and Windows. Keep the app, the files and the readable source bundle.
Four thinking spaces
Work. Life. Learning. Scratch.
Four familiar homes are enough to give ideas a place without turning them into administration. Start a board for what matters now. Finish the project. Leave it behind or return when it becomes useful again.

A board with an open door
Point a compatible AI agent at the folder.
Aetherboard does not trap the board inside an opaque database. Its readable files let a folder-aware agent inspect the same material and, when you choose, propose validated changes through the board inbox.
