Perquira — Evidence organizer for researchers

Free evidence organizer for researchers. Highlight evidence anywhere, file it by manuscript section, export a cited Word draft.

Perquira is a free evidence organizer for people writing real papers: theses, systematic reviews, empirical studies. THE PROBLEM You read 80 papers. The perfect supporting sentence for your Method section is in one of them. Which one? Highlighters, folders and reference managers store papers — none of them store the evidence itself where it will be written. HOW PERQUIRA WORKS 1. Highlight — on any journal page, publisher site, or PDF (Perquira has its own PDF reader). Select the sentence worth keeping and click "Add to Perquira." 2. File by section — choose where it belongs in YOUR paper: Introduction, Method → Participants, Discussion. Sections adapt to the paper type: a systematic review gets PRISMA-shaped Methods; a thesis gets its literature-review chapter. 3. Export — one click produces a manuscript-formatted Word draft: every quote in place, cited, references deduplicated. CITATIONS DONE PROPERLY - Captured at the moment you save — DOI-resolved metadata from Crossref - Five styles: APA 7, MLA 9, Chicago author-date, Harvard, Vancouver — switch anytime, everything reformats - Weak sources are flagged for checking instead of silently polluting your reference list - If a saved sentence itself cites another study, Perquira marks it as possibly secondary — read the primary source before a reviewer tells you to RESEARCH MEMORY Reopen any paper already in your library and Perquira recognizes it by DOI — showing what you saved from it, in which projects, and the verdict you left yourself. Never ask "have I read this before?" again. BUILT FOR EVERY PAPER TYPE Empirical (quantitative and qualitative), literature review, systematic review, scoping review, methodological review, theoretical papers, theses and dissertations. PRIVACY Your evidence is stored locally in your browser. Nothing is uploaded. Citation lookups send only the DOI to Crossref. No account. No payment. Free.
