How It Works

An Open Sandbox

Sketch.Social is built to be open-ended. At its heart the idea is simple: you draw something, you share it, and from there the whole community can build on it.

There's no single "right" way to use it. Make art on your own, jump into a sprawling collaborative comic, run a challenge, or just doodle for fun — the canvas is yours. This guide walks through the drawing tools, how posting and threads work, and some of the things people get up to here.

The Drawing Tools

Everything lives in the toolbar beside the canvas. Click an icon, or tap the number keys 1–8 to switch in a flash.

Circle Brush 1

A smooth round brush for natural strokes, sketching, and clean line work.

Square Brush 2

A flat, chisel-like brush great for bold edges and calligraphic strokes.

Eraser 3

Rub out parts of the layer you're working on.

Fill Bucket 4

Flood-fill an enclosed area with your current color in one click.

Text 5

Drop text onto the canvas — type it, then confirm or cancel before you draw again.

Insert Image 6

Import a PNG, JPG, or WEBP (under 20MB) — bring in photography, digital pieces, or any other kind of art you want to share or build on.

Halftone Brush 7

Comic-style dot shading. Pick a smooth or rough texture and how dense the dots are.

Soft Airbrush 8

A feathered, buildable spray for shading and glows — adjust the flow to layer it up.

• Color picker (eyedropper): sample any color that's already on the canvas.
• Size & Opacity sliders: scale your brush and dial in how transparent it is.
• Color swatches: ten slots you can fill with your favorite colors and reuse.
• Layers (up to 4): stack, reorder, hide, and merge them — think transparent sheets sitting on top of each other.
• Undo / Redo / Clear: step backward and forward, or wipe the canvas to start fresh.
• Pan & Zoom: grab the hand tool to move around, and zoom in to get the details just right.

Posting & Threads

When you're happy with a sketch, hit Post Sketch. Add a caption if you like, choose whether to lock it, and it goes live for the community. (You'll need a free account to post.)

Here's the part that makes Sketch.Social different: every sketch can be remixed. When someone builds on your drawing, their version stays linked back to yours — forming a Thread, an art family tree that shows how a single idea grew into many. You can follow a thread from the very first sketch all the way down its branches and watch the idea evolve.

Beyond drawing, you can explore profiles to see an artist's sketches, followers, and the people they follow, follow creators whose work you love, and report anything that breaks the community rules so moderators can take a look.
