Sketchy lines, a hand-written font, marker colours — the feel of a napkin sketch, with the tools of a real editor. In the cloud from the first stroke, and it draws your Mermaid and JSON for you.

What it does
Everything a whiteboard should do, drawn the way you'd draw it.
The look of a sketch, the manners of a native app.
Draw like on paper
Rectangles, diamonds, ellipses, arrows, free-hand strokes and text — all with the same sketchy hand, and a hand-written font to match.
Arrows that stick
Bind an arrow to a shape and it follows the shape around. Snap to the grid or to neighbours, with guides that show the jump.
Frames with names
Gather part of a drawing into a frame, give it a name, and move it as one thing. Double-click any shape to write in it.
In the cloud from the first stroke
No files to manage. Your whiteboards are saved as you draw, with a dashboard of previews, folders, favorites and a 30-day trash.
Tabs, like a browser
Open whiteboards side by side in one window and drag the tabs into the order you like. Home is always the first one.
Mermaid and JSON, drawn
Paste a Mermaid flowchart or sequence diagram and it lands as shapes and arrows you can edit. Paste JSON and it opens up as connected cards, key by key.
A laser for talking
Point at things while you explain. The red trail fades as you go and leaves nothing on the page.
Share and comment
Share a whiteboard with a link — editors or viewers — and pin comments right on the drawing. Part of chalkdraw+.
Made in chalkdraw
Start from a template, or from a blank page.
Every one of these ships with the app and is a copy away. They're also exactly what the app draws — exported by its own engine.

Questions
The things people ask first.
Can I turn text into a diagram?
Yes. Paste Mermaid — a flowchart or a sequence diagram — onto the canvas, or open Insert ▸ Diagram, and it is drawn as real shapes, arrows and frames you can move and restyle. Paste JSON and every object becomes a card of its keys, connected to the cards nested inside it.
Is it native?
Fully. It's written in Swift and SwiftUI with its own Core Graphics engine — no web view. Keyboard shortcuts, menus, drag and drop and tabs all behave the way they do everywhere else on your Mac.
Is there an iPad version?
Not yet — it is next. The iPad app will open the same cloud whiteboards, with the Apple Pencil, and chalkdraw+ is one purchase for both, so it will be yours there too.
Where is my work stored?
In the cloud, from the first stroke, tied to your account — a guest account made on first launch, or your Apple account once you sign in. Nothing lives only on one device; nothing needs saving.
What does the free plan include?
One whiteboard, with every tool and every template, in the cloud on every Mac you sign in on. chalkdraw+ removes the limit and adds sharing by link and comments.
Can I get a refund?
Purchases go through the App Store, so refunds follow Apple's policy — you request them at reportaproblem.apple.com.
Ready when you are.
Open it, draw the first box, and it's already in the cloud.
