A reading note is more useful when the thing you read sits next to it.
On desktop
Type / and choose PDF, or drag a PDF file straight into the editor. The PDF renders inside the note with a page preview, so you can check the source without leaving your notes.
On mobile
Open the attachments group on the toolbar above the keyboard and choose PDF, then pick the file. On the phone a PDF shows as a compact card with its page count and size.
A working pattern
Drop the paper or contract into the note, then write your summary above it with page references. Later, search finds your summary and the words inside the PDF, and the source is one scroll away for checking.
Ask the AI about it
Grape reads the text of a PDF once, on your device, so the chat, the study tools and search all work from what it says. You can ask the AI about a PDF without attaching it again, or make flashcards straight from a note that is mostly a PDF. How Grape reads the PDFs in your notes explains what reads it and what stays on the device.
Where PDFs live
Attachments belong to the note, in your local library. With sync on, they follow the note to your other devices.
