Start with the messy version
Write with Apple Pencil, draw shapes, type a line, or paste a photo. Nothing has to be tidy first.

ROUGH INPUTANCHORED QUESTIONEDITABLE OUTPUT
The canvas and the AI
look at the same thing.
Every conversation stays attached to the place that started it. Answers land on the canvas—not in a separate chat you have to copy from.
Point to what matters
Select a region in Board mode, or tap and drag with Ask in Write mode. The question stays anchored there.
Build the next version
Get a structured board, plan table, or image directly on the canvas. Follow up to revise it in place.
A working surface for
thinking in motion.
WRITE MODE
Paper when you want paper.
Pen, highlighter, eraser, and a page that stays out of the way. In Pencil-only mode, your palm won’t leave marks. Use two fingers to move and zoom, or enable finger drawing. Apple Pencil double-tap switches tools.
Ask
Questions for the first draftWhat does the reader need to understand first?Context keeps its place.
A highlight marks the source region while the full conversation remains available in the side panel.
Talk about any detail.
Capture a selection and drag it into the conversation for focused visual context.
Revise, don’t duplicate.
AI lays out boards and plan tables on the canvas, then updates the same artifact when you follow up.
Share when it is ready.
Send a note by link with viewer or editor access. Your canvas autosaves while you work.
A little less guesswork.
Do I need an Apple Pencil?
No. Use a mouse and keyboard on the web, or draw with touch. On iPad, Pencil-only mode helps prevent palm marks; the hand control in the Write toolbar enables finger drawing.
Will my notes sync between devices?
Sign in with the same account on iPhone, iPad, and the web to access your saved notes. An internet connection is needed to sync and use AI.
Can I edit or share what AI creates?
Boards and plan tables stay editable on the canvas. Share a note by link with viewer or editor access, and keep refining it with anchored follow-up questions.
Your idea does not
have to be finished.
Roughline helps with the rest.
