CanvasPrism
Graphics & DesignYour Private, Offline Whiteboard
An infinite canvas for sketches, diagrams, and mind maps that works fully offline. No account, no uploads — draw with Apple Pencil, style with 100+ fonts, and export to PNG, PDF, or SVG.
Board, Diagrams, and Design
Sketch freehand, snap to shapes, and build visual designs on an infinite canvas. Smart connectors keep flowcharts tidy as you rearrange, so ideas stay legible from first stroke to final polish.
All Your Diagrams in One Place
Pick up any board you've drawn — system architecture, database schema, mind map, wireframe — from a searchable gallery grouped by folder, with previews you can spot at a glance.
Precise Drawing Tools
Pick pen colors from vibrant, soft, earthy, and neon palettes — or dial in an exact hex code. Custom swatches and shape defaults keep every board on brand.
Reusable Shapes and Components
Star your go-to shapes and drop them into any board with a tap. Import .excalidrawlib component libraries and keep a personal palette of arrows, blocks, and icons ready to go.
From Flowcharts to Schemas
Model whatever you're thinking about — user flows, service maps, database schemas — with drag-to-connect arrows that follow shapes as you move them.
60+ Beautiful Backgrounds
Pick from images, patterns, or solid colors to set the mood — sunsets for kickoff decks, dot grids for wireframes, clean whites for print. Every board can look and feel unique.
Total Color Customization
Pick a background color from vibrant, soft, or earthy palettes, or drop in a custom shade to match a brand. Toggle the dot grid, and watch the whole board respect your choice.
100+ Beautiful Fonts
Search fonts by feeling — Active, Business, Calm, Futuristic, Loud, Rugged — with previews on your own text. Pin favorites and pair a display font with a system default in one tap.
Export to PNG, PDF, and SVG
Ship the board wherever it needs to go — pixel-perfect PNG, vector SVG, or print-ready PDF, with transparent backgrounds when you need them. Save straight to Photos or Files.
Present to Your Team
Switch into a distraction-free presentation view — no tools, no menus, just your board on the big screen. Perfect for design reviews, standups, and walking through architectures.
