Catchii
What it is
Catchii is a web-based tool for screening large collections of scientific literature in systematic reviews. It supports stages from identifying duplicate records through generating a PRISMA flowchart. 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 take reviewer, conflict-resolution reviewer, or manager roles, and screening works offline on a computer, tablet, or smartphone. Grouped, color-coded keywords can mark inclusion, exclusion, or topic terms. The Auto Reviewer uses AI to suggest first-phase inclusion or exclusion decisions and provide justifications; records uploaded for this feature are sent to OpenAI for processing. Selected records can be exported in formats compatible with EndNote, Zotero, or Mendeley, with PDF attachments and a PRISMA flowchart. Catchii is free, with no subscription fees, trial periods, paid upgrades, or advertisements.
