One toolbar, and nothing else to learn
Select, pen, eraser, text, sticky note, shapes, line and arrow: eight modes in a vertical bar, one active at a time. Each has its own letter — V, P, E, T, N, S, D, L — and every button can also be reached with the Tab key.

Write, stick, sketch
The pen writes in 9 strong colours, white included for writing on the black background, each available in five lighter or darker shades, and a free colour picker steps outside the palette as well. Text drops in at three sizes, sticky notes take the colour you choose, and six shapes are available: rectangle, ellipse, triangle, diamond, hexagon and star. Any object can also turn transparent, from 10 to 100%.

Lines, and arrows that follow what they connect
Line mode draws a straight line in one stroke, or a jointed line vertex by vertex, for a free-form diagram. Arrow mode hooks onto an object at either end, through the “+” points that appear on the object you select: move the note and the arrow follows. The line is solid or dashed, and the head can be single, double or absent.

Room to move, without getting lost
The canvas is 8000 by 6000 units — large, but bounded on purpose. Zoom runs from 10 to 400%, by wheel, by button or by pinching with two fingers, and “See all” reframes on what you drew. The background can be plain, grid, lined, dotted or ruled like handwriting paper, and the canvas itself can be cream, white or black — the ink then switches to white to stay readable.

Step back, wipe, take it with you
Two erasers, whichever suits: “Whole stroke” lifts a stroke in one touch, “Brush” cuts it where you sweep. “Clear all” asks for confirmation, and undo goes back up to a hundred moves. A board can be exported as a PNG or a PDF.

Add a photo, a scanned drawing or a diagram
The “My device” panel poses an image by file picker, drag-and-drop or paste (Ctrl+V), in png, jpeg, webp, gif, bmp, up to 25 MB per file. It is shrunk and kept in this device’s browser, never sent to a server — that is what keeps it private. Once placed, it resizes keeping its proportions and can be cropped.
