To use progressive summarization with PDFs, here’s what I do:
1. I highlight and comment passages in PDF Expert (which is my layer 1):
/quality(80).jpeg)
2. I export my highlights and annotations in text format:
/quality(80).jpeg)
Which results in:
/quality(80).jpeg)
3. I copy and paste my highlights and annotations into Microsoft OneNote:
/quality(80).jpeg)
4. And then I’m ready to go to layer 2, layer 3, and layer 4:
/quality(80).jpeg)
Tips and tricks
When doing Layer 3 (highlighted passages), I use gray color instead of yellow because the searching tool in OneNote already uses yellow, which can get confusing when looking for a keyword. So I get:

instead of:

When I annotate or comment, I make sure to use asterisks. Otherwise, it’s hard to distinguish the highlights from the annotations once the text is exported:
/quality(80).jpeg)
I do the same when I summarize a passage: I add ((( resume ))) to make it easier to distinguish later on.
