Endless Paper An infinite canvas for thinking, drawing, and storytelling Endless Paper is a creative tool built around a truly infinite canvas. Write handwritten notes, create immersive artworks, explore ideas visually, and connect everything in one continuous space. Deliberately simple yet powerful and incredibly fast, it feels as natural as pen and paper—without the limitations of physical media. Whether you’re a student organizing notes, an artist exploring large-scale compositions, or a team lead mapping out complex ideas, Endless Paper adapts to the way you think and communicate visually. HIGHLIGHTS • A truly infinite canvas • Ultra-crisp, vector-based drawings at any zoom level • Move, resize, and duplicate content using a powerful lasso tool • Convert images into clean, zoomable vectors with vectorization • Create vast canvases with minimal storage usage • Export high-resolution images, PDFs, and videos with automatic zoom • Publish your canvas as an interactive website • Drag and drop images, PDFs, and even websites from other apps • Adaptive bullet grid that responds to zoom level • Bookmarks for fast navigation across large canvases • Organize multiple canvases in a cohesive gallery with versioning • Customizable color themes and dark mode • Broadcast a live view of your canvas to the web • Unlimited undo and redo • Continuous autosave with an integrated archiving system • Designed to minimize errors and cognitive load • Powered by Fractile, a Metal-accelerated 64-bit vector rendering engine DRAW BEYOND THE FRAME Endless Paper enables a new form of long-format visual storytelling.

Verdict

The call

On price, ads and in-app purchases there is nothing between them.
