How to organize research papers and PDFs so you can find what's inside them
Keep every paper in one place, name files the same way, and use a reference manager such as Zotero for citations. Then add what folders can't give you: a way to search what papers say, not just their titles. Screen new papers on summaries, group live projects into collections, and ask across your PDFs when you need a half-remembered passage.

Step by step
- 1Give papers one homeNot Downloads, not the desktop, not email attachments. One place where every paper goes, on the day you get it.
- 2Use one naming ruleAuthor–year–short title, for example “Smith-2021-sleep-and-memory.pdf”. It sorts sensibly and tells you what a file is without opening it.
- 3Let a reference manager handle citationsZotero (free) or similar tools store metadata and format bibliographies. That's their job; don't do it by hand.
- 4Screen before you readDecide in two minutes whether a paper deserves an hour. A summary, the key findings and the method are usually enough to make that call.
- 5Make the contents searchableTitles and file names only get you so far. Use a tool that reads the papers, so you can search for a method, a finding or a term, and get back the paper and the passage.
Why research PDFs pile up
Papers arrive from everywhere: database searches, citation trails, a supervisor's email, a link in a talk. Each one lands wherever that app puts files, with whatever name the publisher gave it. After a semester you have hundreds of PDFs and no idea which one had the result you need.
Two jobs, two tools
Organising papers is really two jobs. One is bibliographic: authors, years, journals, formatted citations. Reference managers such as Zotero do that well. The other is remembering what papers say and finding the passage again, which reference managers mostly leave to you.
Kajr covers the second job. Share a PDF or paper link into it and it arrives with a summary, key takeaways and tags. Later you can ask which papers used a particular method, which ones disagree, or where you read a claim, and Kajr answers with the papers it drew on.
A setup that works on your phone too
A lot of screening happens away from a desk: on a commute, between meetings. With papers in Kajr you can triage from summaries on your phone, put the ones worth a full read into a collection, and do the deep reading later. Your library stays on your device and can sync to your own Google Drive.
Always check a claim against the paper itself before you cite it. A summary tells you where to look, not what to write.
Questions you can ask Kajr
- Which of my saved papers used a randomized controlled design?
- Where did I read that sleep affects memory consolidation?
- Which papers in my library disagree about sample size?
Frequently asked questions
What is the best way to organize research papers?
One storage location, a consistent file naming rule, and a reference manager for citations. Add a tool that can search the contents of papers, so you can find a finding or method, not just a title.
Is Zotero enough on its own?
For citations and bibliographies, yes. It's less suited to asking questions across what papers say. Many researchers pair a reference manager with a tool that reads and summarizes their PDFs.
Can Kajr read PDFs?
Yes. Share a PDF into Kajr from Files, Mail, a browser or any app that can show it. It's added to your library with a summary, key takeaways, action items and tags.
