Abstrackr
What it is
Abstrackr is a web-based citation-screening tool for systematic reviews, intended for researchers, librarians, and review teams. It supports solo screening and team workflows with blinding, pilot rounds, and conflict resolution. After roughly 100 labels, its machine-learning model orders remaining citations by predicted relevance. A live PRISMA flow table tracks screening thresholds, resolved conflicts, exclusion reasons by tag, and model stop-point analysis. Citations can be imported from PubMed, Scopus, and Embase, or through RIS and CSV files. The tool removes duplicates using DOI and PMID, with an option to combine near-duplicates that remain. Exports include CSV, RIS, and JSONL. Blinding starts enabled, and changes are logged with user, reason, time, and project snapshots. Projects use Member and Leader roles without a team-size limit; assignment reminders arrive 7, 4, and 1 day before deadlines. Abstrackr is free, has no seat limits or usage caps, and requires no installation. Methodology and workflow discussions are directed to its community forum.
