What Catchii is
Catchii is a web-based systematic review screening tool for working with large scientific literature datasets. It covers review stages from duplicate detection through PRISMA flowchart creation. References can be imported from PubMed, Scopus, Web of Science, OVID databases, CSV files and reference management software. Its duplicate detector flags records with highly similar titles or abstracts for review. Teams can screen titles and abstracts, move to full-text analysis, resolve disagreements and extract data from included articles. Multiple users can have reviewer, conflict-resolution reviewer or manager roles, and screening is available offline on a computer, tablet or smartphone. Grouped, color-coded keywords can highlight inclusion, exclusion or topic terms. The Auto Reviewer uses AI to assist first-phase screening with inclusion or exclusion decisions and justifications; uploaded records are sent to OpenAI for processing. Selected records can be exported in formats compatible with EndNote, Zotero or Mendeley, along with PDF attachments and a PRISMA flowchart. Catchii is free, with no subscription fees, trial periods, paid upgrades or advertisements.
