Helicon
Write in the margin of your PDFs with Apple Pencil.
Press and hold the margin, and a pin drops beside the line. The pin opens a note. Type in it, or write in it with Apple Pencil.
No account. For iPhone and iPad with iOS 26 or later.
A pin, right where you read.
The pin sits in the margin beside its line, so the page stays clean. Your text and highlights stay as they were. Tap the pin to open the note again.
Search finds what you wrote.
Helicon reads the words in your handwriting. It also turns a voice note into text, on your device. Search finds a margin note by those words, as it finds words you typed.
