ASReview vs Catchii

ASReview is a free, open-source tool that uses AI-aided active learning to prioritize records for systematic review screening, with a human making screening decisions. Its site says the approach can reduce screening workload by up to 95%. Users can simulate AI-aided review to compare models, while Crowdscreen supports parallel screening with access managed by administrators through a private login system. The described model families are ELAS-Ultra, ELAS-Heavy, and language-agnostic ELAS-L; ELAS-Heavy and ELAS-L require the Dory package. ASReview works with reference managers including EndNote and PubMed, and imports and exports CSV, RIS, and XLSX files. Documentation includes a Python API, while the institutional workflow also describes a REST API and CLI for automation. In a local setup, data stays on the user's computer; server deployments keep it in the organization's environment and follow its policies. Support includes documentation, tutorials, videos, community discussion, and organizational workshops and consultancy. ASReview LAB costs nothing with no licensing fees or subscriptions, though running hardware or a server may incur costs.

Catchii is a web tool for screening large scientific-literature datasets in systematic reviews. It covers duplicate detection, title-and-abstract screening, full-text analysis, disagreement resolution, data extraction and PRISMA flowchart generation. References can be imported from PubMed, Scopus, Web of Science, OVID databases, CSV files and reference-management software. The duplicate detector identifies records with highly similar titles or abstracts for review. Multiple reviewers can be assigned roles such as reviewer, conflict-resolution reviewer or manager, and screening works offline on computers, tablets and smartphones. Customizable grouped, color-coded keywords mark inclusion, exclusion or topic terms. The Auto Reviewer uses AI to assist first-phase decisions with inclusion or exclusion explanations; uploaded records are sent to OpenAI for processing. Exports work with EndNote, Zotero or Mendeley and can include PDFs and a PRISMA flowchart. Catchii has a free plan with no subscription fees, trial periods, paid upgrades or advertisements.
