Easily Create Citations and Bibliographies. Research is Hard, Citations Shouldn't be.
Privacy Statement: SourceKeeper is not interested in your data, does not collect your data, does not save any data (everything is on your phone not on our end) and certainly does not share what it has not collected nor saved. We do not advertise to you and do not sell upgrades. Buy Pro for 1.99 and forget it.
Mission
Academic writing demands precision, and citations are no exception. A misplaced comma, a wrong edition format, or an editor's name in the wrong field can mean lost marks or a returned manuscript.
SourceKeeper was built on a simple idea: your phone already knows how to read a barcode. It should be able to hand you a formatted citation on the spot. From there, the vision grew — into a full research companion that handles every source type, every major style guide, and every stage of a project, from the first scan to the final export.
We built SourceKeeper for students writing their first research paper and for academics who have written dozens. It doesn't try to replace your word processor or your library database. It just handles the part that everyone dreads.
How It Works
1. Capture your sources Scan a book's ISBN barcode and SourceKeeper pulls the title, authors, publisher, and date automatically. Photograph a journal article page and it reads the metadata for you. Or enter any source by hand in seconds.
2. Organize by project Group sources into projects — one per paper, chapter, or course. Add notes to any source. Mark which ones belong in your master bibliography.
3. Generate citations Every source produces a correctly formatted footnote and bibliography entry in Chicago 17th, MLA 9th, or APA 7th edition. Switch styles at any time.
4. Export to your word processor Export a bibliography or footnote list for any project — or a master bibliography across all your projects — as an RTF file that opens in Word, Pages, and Google Docs with formatting intact.
