How kagaj works.

Open kagaj on your iPad and tap the floating + button at the bottom-right. A small popover opens with New note, New folder, and Import file. That's it. There's no account to make, nothing to sign in to, no settings to flip. Pick up your Apple Pencil and start drawing.

Everything you create stays on your iPad. You can use kagaj offline, on the bus, on a plane, anywhere.

The Library is where every note lives. It's a grid of cards. Notes look like little ruled pages. Folders look like cardstock tabs.

• Tap a note to open it. Tap a folder to look inside.
• Folders can hold notes and other folders, as deep as you want.
• Search finds folders and note titles.
• Pin the notes and folders you come back to most.
• Long-press any card to enter Select mode. Pick several at once to move or delete them together.
• You can bring in plain text and PDFs from Files. PDF pages are kept as backgrounds so you can write and draw on top of them.

A note is a stack of pages. Each page is the size of a letter sheet, and you can pick whether it's ruled or plain. Pages flow top to bottom, the way a real notebook does.

• Tap above or below a page to add a new one.
• Pinch with two fingers to zoom in. Double-tap to snap back.
• Each page shows where it sits in the note (page 2 of 5, for example) and has a small button to remove it.
• Tap Share to send the whole note as a PDF. Your ink comes along.

Want to focus? Tap the fullscreen button to hide everything but the page.

The tools palette is a small floating bar at the bottom of a note. It's where you pick what your Pencil does. kagaj is a hand-written notebook, so there's no text tool. Typed text already lives in plenty of other apps. This one is for ink.

Six colours to pick from: black, red, blue, mango green, amber, plum. The pen, pencil, highlighter, and eraser each have a size slider so you can dial the stroke up or down. The palette gives a tiny haptic tap when you switch.

To open the palette quickly: squeeze your Apple Pencil Pro, or double-tap the side of a Pencil 2. Or just tap the tools chip in the toolbar.

kagaj is designed around the Pencil. Your Pencil is for writing and drawing. Your finger is for everything else: scrolling the page, pinching to zoom, tapping buttons. The two never get confused.

Your notes live on your iPad. Nothing leaves your device unless you choose to share a PDF. There's no account, no cloud sync, no servers in the middle.

kagaj saves as you write. You don't need to think about it. If you close the app or your iPad runs out of battery, everything is already there when you come back.
