What Parsifal is
Parsifal is a free web tool for planning, conducting, and reporting systematic literature reviews. Its planning covers objectives, PICOC, research questions, keywords, search strings, selection criteria, quality questions, and data extraction forms. Researchers can import BibTeX records from Scopus, Web of Science, IEEE, ACM, and PubMed, as well as use API imports. The platform supports accept-or-reject screening, duplicate detection, quality assessment, and snowballing through references and citations. Review owners can add co-authors to edit protocols, screen articles, and generate content, or share a public read-only link. Parsifal can create PRISMA diagrams and export review data to Excel or CSV, with papers available in Word, LaTeX, and PDF. It lists more than 45 community templates across 12 domains and six languages. Its optional AI assistant can suggest protocol material, assist with article screening, quality assessment and data extraction, and generate paper sections. Using it requires your own Anthropic or OpenAI API key, and you pay the AI provider directly for usage. Imported articles, screening decisions, and extraction data are stored in the user's account database.
