Paperly is paper reader designed for researchers. Its goal is to improve the whole experience of reading, reviewing and thinking in a reader.

Three key features are provided correspondingly:
1. WYSIWYG Citation;
Scrolling PDF document to the end for checking the reference information is a time-wasting and distracting operation. What’s worse, most of us can not quickly go back to or even lose the citation place where we have just read.
(1) Citation Tooltip: show the reference information when the mouse moves to a citation in text.
(2) Reference sidebar: lists all the references in a sidebar for quick searching.
Below features are also provided:
(3) Local citation frequency?—?the number one reference has been cited in this paper.
(4) Metadata?—?DOI, abstract, keywords and etc. of each reference.
(5) Mark?—?meet any important reference, mark it down.

2. Contextual Notebook;
The biggest problem of taking notes on traditional PDF readers is: all notes are stored in the PDF files and can not be extracted to a notebook.
With Paperly, all notes you took on PDF are collected automatically into a notebook which can also go back to the context of any note. The tag system is embedded so you can use tags to manage your note neatly.


3. Scholar Mind Graph
Link your papers & notes& keywords & tags.
Three types of graph are provided to help you organize your knowledge:
(1) keyword graph:
If two papers share the same keywords, they would be linked by the keywords.
(2) tag graph:
If two notes share the same tags, they would be linked by the tags.
(3) link graph:
(The ‘#’ function is just like the one on Twitter to mention some topics.)
“this idea is much the same as #paper1”
“for further data analysis, check #paper2”.
