Helicon
Open a paper as a PDF. Hold a finger in the margin, and a pin drops beside the line you want to argue with. The pin opens a note that holds typing, Apple Pencil ink, a checklist or your voice.

An older paper is often a scan. Helicon reads its words on your device with Apple's Vision, so you can select, highlight and speed read a scanned page like any other.
Search finds the author's words and your own notes, and shows your notes first. Review brings back the questions you wrote, so a paper you read last month still has its point.
