I'm a student drowning in lecture PDFs, screenshots and voice memos. What iPhone app keeps it all searchable?

A term usually lives in three places at once: a slide you screenshotted, a PDF the lecturer posted, and a recording of the class. Nemos reads the words inside screenshots on your device, searches PDFs by their contents, and turns voice recordings into transcripts you can search.

A workable setup is one folder per course. Add the PDFs from Files or through the share sheet, screenshot slides as they appear, and record the lecture with one tap. Before an exam, search a term and see every source together. You can also ask the AI chat what your saved material says about a topic, then check the answer against the source.

Reminders help with deadlines. Attach one to the assignment PDF so the file is there when the reminder fires.

When something else fits better: if you annotate PDFs by hand with a pencil, a dedicated notebook app such as Notability or GoodNotes does that job, and Nemos can stay the place where you search everything else. Ask your lecturer before recording a class.
