One thought, room to grow

Start wide. Go deep.

Notasy keeps the path from source material to handwritten insight visible.

Think beyond the page

Use two fingers to pinch, zoom, and pan while your ideas grow into a full study map.

Read PDFs with context

Import a PDF, then write with your stylus in the note lane beside the material.

Dive into details

Place a flag, tap it to open a focused sub-canvas, then return with context intact.

Keep the thread alive

From your tablet to the bigger picture.

Move between trusted devices

Open Sync, choose a currently available nearby HarmonyOS device, and sync the note locally.

Present on a bigger screen

Start Cast, open the local link in a computer browser, and watch new stylus marks appear live.

Clear by design

What Notasy means by connected.

Local sync requires a selected, currently available nearby HarmonyOS device. OCR search applies only to canvases without an attached PDF. PDF pages remain a read-only background beneath your notes, and casting works only while the note remains open.
