Drawing canvas

Draw the part words cannot carry.

Some thinking is spatial. Grape has an infinite canvas that lives inside a note, so the sketch and the writing about it never end up in two different apps.
Freehand drawing, shapes, arrows and boxes
The canvas sits in the note as a block, with text above and below it
Follows dark mode, so a canvas drawn at night still reads in the morning
Drawings sync with everything else on a Pro plan
Diagrams without a second app
Boxes and arrows are two clicks away instead of a context switch.
Sketch, then explain underneath
The caption you write is what makes the drawing findable later.
Draw with a pencil in hand
Rough it out on the phone, tidy it up at the desk.

Your Notes Are Worth More Than You Are Getting Out of Them

Download Grape, point it at a folder, and see what one week of notes looks like when you can ask them questions.
