Catchii vs Universal SLR Assistant

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.

Universal SLR Assistant supports systematic and scoping reviews with AI-assisted screening, extraction, and reproducible outputs. It provides a desktop interface and a browser-based local Web App, and imports RIS, BibTeX, CSV, and plain-text references, including exports from PubMed, Scopus, and Web of Science. Its workflow covers abstract screening, full-text PDF processing, structured extraction, and export; likely duplicates are identified by DOI and fuzzy title matching. Workspace mode stores references, PDF metadata, review items, decisions, and audit events in a local SQLite workspace, separating AI suggestions from human decisions. Exports can include decision files and logs, exclusion reasons, PRISMA-ready counts, a methods disclosure draft, and a manifest. The project supports a range of cloud and local AI providers. Cloud providers receive submitted paper text, while Ollama or another local endpoint can keep it on the user's computer or local network. AI results are assistance only: people must verify them and make final review and reporting decisions. The software is free under the MIT License; cloud AI provider API fees may apply.
