Your ideas don’t have to be finished

Think in rough lines.
Leave with a real plan.

Sketch it, write it, paste it in. Then ask AI about the exact part you’re working on—and watch the answer take shape right beside it.

Not another empty whiteboard.

The canvas and the AI
look at the same thing.

Roughline keeps every conversation attached to the place that started it. No copying answers out of a chat. No losing the context behind a decision.

01

Start messy

Write with Apple Pencil, draw shapes, type a line, or paste a photo. Roughline is built for the version before the polished version.

02

Point to what matters

Select a region in Board mode, or tap and drag with Ask in Write mode. Your question stays anchored to that exact spot.

03

Build the next version

Get a structured board, plan table, or image directly on the canvas. Ask again and Roughline can revise the artifact in place.

Made for thinking in motion

From first mark
to next move.

Everything stays in one working surface—from the loose thought to the structure you can use.

WRITE MODE

Paper when you want paper.

Pen, highlighter, eraser, and a page that gets out of the way. Apple Pencil writes while your fingers pan; double-tap switches tools.

Ask
Questions for the first draft

What does the reader need to understand first?

Conversations keep their place

A highlight marks the source region, while the full thread stays readable in the side panel.

Talk about any detail

Capture a selection as a snapshot and drag it into the conversation for focused context.

Plans that stay editable

AI can lay out boards and plan tables on the canvas. Follow up to revise the same plan instead of adding another copy.

Share when it’s ready

Send a note by link with viewer or editor access. Your canvas autosaves as you work.
