Axelium vs Catchii

Axelium is an AI-assisted platform for systematic reviews and meta-analyses, spanning evidence search, screening, analysis, reporting, and living reviews. Its 11 stages include protocol, search, screening, full-text review, extraction, RoB 2.0, GRADE, statistics, network meta-analysis, reporting, and living reviews. The maker says AI extracts structured values while deterministic code calculates statistics, and data points link to snippets in original PDFs. Listed methods include pairwise and network synthesis, Cochrane RoB 2.0, GRADE certainty ratings, CERQual, and PRISMA-style reporting. It imports references from tools and databases including EndNote, Zotero, PubMed, ClinicalTrials.gov, and Web of Science; exports include DOCX, XLSX, RIS, BibTeX, and RevMan. Team controls include roles, comments, dual-person sign-off, conflict adjudication, and versioned audit snapshots. A free plan includes one lifetime review and one seat; Researcher costs $29 a month. Human validation is needed for screening suggestions, extracted values, risk-of-bias assessments, and draft reports. Recurring statistical refresh for living-review network meta-analysis is paused, though scheduled cycles can import, screen, and extract new evidence.

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.
