Parsifal is a web tool for planning, running, and reporting systematic literature reviews. Its planning covers objectives, PICOC, research questions, keywords, search strings, selection criteria, quality questions, and extraction forms. Researchers can import BibTeX records from Scopus, Web of Science, IEEE, ACM, and PubMed, or use API imports. During a review, they can screen studies against inclusion and exclusion criteria, track progress, assess rigor and relevance with weighted criteria, identify duplicates, and expand results through references and citations. Review owners can invite co-authors to edit protocols, screen articles, and generate content, or share a public read-only link. Parsifal creates PRISMA diagrams and exports review data to Excel or CSV and papers to Word, LaTeX, or PDF. More than 45 community templates are listed across 12 domains and six languages. Its optional AI can assist with screening, assessment, extraction, protocol suggestions, and paper sections; it requires the user's Anthropic or OpenAI API key, with usage billed directly by that provider. The free plan costs 0.00 USD per free.
Who it is for
Parsifal suits researchers conducting systematic literature reviews, including teams that need shared protocol and screening work. Its free plan may suit users who want review tools without the optional AI assistant.
