Exsto: Concept Art Sketching

Exsto is an experimental drawing and concept-sketching tool built for artists. Explore characters, creatures, environments, compositions, and unexpected forms with expressive strokes, mirror drawing, symmetry, and three-point perspective.

Exsto is designed for the beginning of the creative process—the fast, loose stage where you test shapes, develop variations, and follow unexpected directions. Natural variation in every movement becomes part of the result, helping you find forms you might never have planned.

DRAW IN PERSPECTIVE

Position three vanishing points, select a ground or wall plane, and draw directly onto it. Exsto maps your strokes and their expressive variation into the selected plane, while an adaptive grid helps you understand the space as you pan and zoom.

EXPLORE WITH MIRROR AND SYMMETRY

Mirror your strokes in real time around an adjustable axis. Use symmetry to develop balanced characters, creatures, props, vehicles, architecture, and unexpected abstract forms.

EXPLORE SHAPE AND FORM

Exsto’s organic stroke behaviour responds to subtle variations in your movement. Work loosely, push shapes in different directions, and develop the strongest results further.

MADE FOR APPLE PENCIL

On iPad, Exsto responds to Apple Pencil pressure, tilt, speed, and movement. Subtle variations in your input influence each stroke, giving you direct control without removing the unexpected qualities that make exploration productive.

WORK ACROSS IPAD, IPHONE, AND MAC

Every Exsto canvas is an editable document. Save your work in iCloud Drive or your preferred Files-compatible cloud service, begin a concept with Apple Pencil on iPad, continue working on Mac, and keep ideas close on iPhone. You can also share the original Exsto document without flattening your artwork.

Built natively for Apple platforms using Metal and SwiftUI, Exsto delivers fluid, responsive drawing across your devices.

CONTINUE CREATING FROM THE HOME SCREEN

The interactive Creation of the Day widget lets you add strokes directly from your Home Screen. Build an image gradually throughout the day and return to Exsto when an idea begins to take shape.

MOVE IDEAS INTO YOUR WORKFLOW

Export your work as PNG, JPEG, TIFF, or SVG. Continue developing your concepts in another art tool, share exported artwork with collaborators, include it in a presentation, or use it as the foundation for a finished piece.
