Catchii vs Elicit

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.

Elicit is an AI research assistant for researchers gathering and assessing evidence. Its Research Agent draws on scientific databases, academic journals, public data sources, uploaded documents, a corpus of 138 million academic papers, and the wider web. A session can use up to 20 uploaded resources, including PDF, DOCX, XLSX, PPTX, and JPG files. Elicit offers Research Agent sessions, Research Reports, and Systematic Reviews, and supports AI-generated claims with sentence-level citations to underlying sources. It can find up to 1,000 relevant papers and analyze up to 20,000 data points at once. Research Reports export as PDF or Word, tables as CSV or Excel, and references as RIS or BIB. Elicit runs on the web and provides an API, but API access requires Pro or above. Its MCP server connects to Claude Desktop, Claude Code, and other compatible clients using OAuth 2.0. Basic is free with limited usage for Research Agent and Research Reports; Plus costs $11 a month. Pro is $39 a month and Scale is $89 a month. Elicit states that it has achieved SOC 2 Type II compliance.
