In their own words
HAWC
HAWC is a free web application for storing, displaying, and synthesizing data used in human health and environmental risk assessments. Its modules support study-quality evaluation, data extraction from human epidemiology, animal bioassay, and in vitro studies, evidence synthesis, and dose-response analysis. Assessment teams can assign managers, members, and reviewers role-based permissions for viewing, editing, and administration. Published material is viewable without an account, while collaboration on an ongoing assessment with EPA scientists requires a Login.gov account and approved EPA HAWC group access. Interactive visualizations connect studies, experiments, endpoints, and dose information. Users can download available datasets as Microsoft Excel files and export figures to PDF or other formats. Benchmark dose modeling is performed endpoint by endpoint at the EPA HAWC chemical manager’s discretion. HAWC supports most modern browsers, with Google Chrome preferred, and reports functionality errors with Internet Explorer.
Parsifal
Parsifal is a web tool for planning, conducting and reporting systematic literature reviews. Its planning process 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, or use API imports. The platform supports article screening against inclusion and exclusion criteria, duplicate detection, quality assessment and snowballing 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 can create PRISMA diagrams and export review data to Excel or CSV, with papers in Word, LaTeX or PDF. It lists more than 45 community templates across 12 domains and 6 languages, and connections to services including ASReview, OpenAlex and Semantic Scholar. Its optional AI assistant can help with screening, assessment, extraction and paper sections, but requires the user's Anthropic or OpenAI API key; AI usage is billed directly by the AI provider. Imported articles, screening decisions and extraction data are stored in the user's account database.
