Metal Brush Engine

Brushes that feel like pens

The writing feel comes from a custom Metal brush engine with seven pens built specifically for Apple Pencil.

Fountain Pen

Responds to pressure so your strokes taper naturally, giving distinct character to your handwriting.

Gel Pen & Highlighter

Smooth, consistent lines for rapid note taking, paired with semi-transparent highlighting for key takeaways.

Pencil

Shades smoothly with tilt and pressure, giving you the natural texture of graphite on paper.

Brush Pen

Features expressive dry-brush streaks as speed increases, ideal for expressive calligraphic strokes.

Watercolour

Blooms with wet edges, layering translucent washes that build depth as colours overlap.

Oil Paint

Builds up thick impasto strokes and picks colour back up from the canvas as you blend.

Stroke styles & responsiveness: Dotted, dashed, wavy, or hollow lines. Touch coalescing and prediction keep latency low, and you can zoom to any level without ink turning blurry.

Study & Research

A workspace for studying from

Most of the time you are writing from something. The reference workspace opens a second item right next to your notes without switching away.

PDF & Markdown Files

Open local PDFs up to 512 MB, remote HTTPS PDFs, or Markdown documents alongside your notebook.

Local & Online Video

Play local lecture videos up to 2 GB or direct HTTPS video streams while you jot down notes.

Split, Overlay & Cornell

Split left-right, top-bottom, stack two layers with transparency adjustments, or use dedicated Cornell regions.

Flexibility

Mixed pages, real paper

Handwriting and typed text share the same book, arranged however you like.

6 Paper Backgrounds

Blank & Ruled

5 Standard Page Sizes

Multimedia & Sharing

Voice, attachments, and PDF export

When you cannot write fast enough, record it. Audio recordings attach directly to the page and can be automatically transcribed into text using system speech recognition.

Photos drop right into your page alongside your handwriting. When you are done, export a single page or the entire notebook as a high-fidelity PDF that prints and shares crisply.

Voice Recording & Transcription

Audio stays with the page; automatic speech-to-text via iPadOS Speech framework.

Photo Attachments

Insert reference photos and diagrams directly into your note pages.

Full-Fidelity PDF Export

Export single pages or complete books with crystal clear vector rendering.

Local-First Architecture

Your data, kept safe in your hands

Your notes are saved locally first. A custom checksummed, versioned binary format saves page by page, so a sudden close won't lose what you wrote.

To sync across devices or back up, place the entire library in iCloud Drive, Google Drive, Dropbox, or a local NAS through the system Files app. Deleted items stay deleted via tombstones, and sync conflicts automatically retain an extra copy.

There are no accounts to create, no servers tracking your habits, and zero advertisements.
