Studying and research

Search the whole reading list at once

Before an exam the question is never "where is this in chapter 4". It is "where did I see this", across a textbook, two sets of lecture slides, a scanned chapter from the library and a dozen papers. Crossleaf searches all of them at once.

What it does

• One search, every file. Type a term and see every place it appears, grouped by document and chapter, with the sentence around it.
• Scanned chapters too. Photocopies and scans without a text layer are read with on-device text recognition, then searched like everything else.
• Straight to the page. Tap a result and the page opens at the match, highlighted. Your results stay put while you check the next one.
• Pencil notes in the file. Annotate with Apple Pencil; the notes are saved into the PDF, so they are there when you open it on your Mac.
• Search history. The terms you keep coming back to are one tap away.

For a thesis literature review

Add every paper you have collected and search a method, a dataset or an author's name across all of them. Results show which paper, which section and which page, so you can find the sentence you half remember without opening forty files.
