Sketch the plan. Fieldnote draws the rest.

A diagram notebook for product teams. Draw a rough line between two boxes and it becomes a real connection: it follows when you move things, carries a note and still reads in six months.

Free for 3 editors. Readers are always free.

1. Rough is the input

Draw with a mouse, a pen or a finger. Wobbly boxes stay wobbly. Fieldnote only straightens a line when you ask it to.

Pen, mouse or touch, with pressure kept on iPad

2. Every arrow knows both ends

Arrows attach where you let go. Move a box and its arrows follow, redrawn in your own stroke, never snapped to a grid.

Up to 400 boxes on one page

3. One highlighter per page

Mark the decision that matters. Each page gets a single yellow pen, so the important thing is never one of twelve.

How a page grows

Three moves, in the order people make them on paper. Every drawing on this page inks itself in the way it does in the app.

Start with a circle

Open a page and draw. No template picker, no shape library to search. A circle is a circle, a box is a box, and both are already things you can connect.

Join them with a dotted path

Dotted means maybe. Drag a dotted line for the routes nobody has decided, then ink it solid when the team agrees. The history keeps both.

Write in the margin

Notes live beside the drawing, never on top of it. Point at anything with a hand-drawn arrow and the note stays pinned when the diagram moves.

Scribble on the real thing

Drop a screenshot onto a page and mark it up like a printout. Rings, arrows and margin notes stay attached to the part of the screen they point at.

Leave the page half finished.

Someone else will pick up the pen. Fieldnote keeps every line, every maybe and the one yellow mark, so the next person starts exactly where you stopped.
