Everything you've gathered, in one library

PERRLA keeps your sources, files, and notes together, and connected to the papers you write.

Bring your Zotero library

Connect Zotero once and PERRLA brings across your references, attached files, notes, PDF highlights, tags, and collections. Working from .bib files? Import those too.

Read and annotate your PDFs

Open a PDF right in PERRLA with the Reference Annotator, highlight what matters, and pin notes to the exact passage. Every note stays attached to its reference.

Organize by chapter

Collections hold the papers, references, and files for each chapter or project, nested however your dissertation is built. One item can live in more than one Collection.

Write with it anywhere

Your library follows you into Microsoft Word, Google Docs, and PERRLA Online. PERRLA formats the paper, the citations, and the reference list in APA, MLA, or Turabian as you write.

Already paying for storage somewhere else?

Connect Zotero and your whole library comes across in one step. Zotero's plans are storage alone; PERRLA's include the whole writing tool. (Prices from zotero.org, September 2026.)
