Custom Ink Engine
Tapered, pressure-sensitive strokes. Pen, pencil, marker, dotted & dashed — each with its own feel.
A handwriting-first workspace. Custom ink, PDF annotation, lasso & laser tools, side-by-side panes — on a canvas that never runs out of space.
Built for iPad with PencilKit, PDFKit, and a custom ink engine. Every tool, exactly where you'd expect it.
Tapered, pressure-sensitive strokes. Pen, pencil, marker, dotted & dashed — each with its own feel.
Capture and reposition any strokes on the canvas.
A soft laser beam for presenting and annotating live.
Import any PDF and ink, highlight, and annotate directly on the page.
Browse your library while keeping notes open — or view two notes at once.
Folders, favorites, smart sections, full-text search, and thumbnail previews of every note.
Start any note on the right paper — ruled, dot-grid, blank, or loose density.
Your notes never leave your iPad.
System-matched, or switch anytime in Settings.
Shake or two-finger tap to undo any stroke or action.
Every stroke runs through a custom-built ink engine. Velocity shapes each line — slow down for weight, speed up for delicacy — just like a real fountain pen.
Pen, pencil, marker, dotted, and dashed styles all use the same engine. The result is handwriting that looks and feels exactly the way you'd expect.
Tap your note's title to split the screen. The other pane becomes a live library browser — find a reference, tap to open it, and keep your current note where it is.
Two notes, side-by-side. No app switching. No losing your place.
No account required. No cloud. No subscription.
Marginless stores everything locally on your iPad — and only your iPad.
Built with SwiftUI, PencilKit, and PDFKit. Every gesture, every scroll, every stroke — exactly as Apple intended.
We're building toward a complete creative workspace. Here's what's coming.
Record audio while you write. Replay anchored to the exact stroke where it was captured.
Automatic summaries, flashcards, quizzes, and progress tracking built from your own handwritten notes.
On-canvas typed text that lives alongside your ink — resize, reposition, and restyle freely.
Diagrams, flowcharts, and drawings made precise — polygons, curves, and custom outlines.
Render beautifully typeset equations inline in your notes, from simple formulas to full proofs.
