What Covexe is
Covexe is a browser-based platform for systematic reviews, meta-analysis, evidence synthesis, and applied statistics. Its review workflow moves from question and search through screening, full-text review, extraction, appraisal, synthesis, and reporting. Supported review types include systematic, scoping, network meta-analysis, diagnostic accuracy, umbrella, rapid, and narrative reviews. Methods include pairwise and network meta-analysis, GRADE ratings, risk-of-bias tools, and a PRISMA 2020 flow diagram. The statistics suite covers regression, survival analysis, diagnostic accuracy, and other methods checked against R packages and implementations. References can be imported in RIS, NBIB, BibTeX, PubMed XML, CSV, and Excel formats, with duplicates detected by DOI and PMID. Users can connect their own OpenAI, Anthropic, or Google AI key. The co-pilot pauses for approval at checkpoints, and AI screening does not exclude a study without approval. Signed-out work stays in the browser; signed-in reviews are stored for cloud sync and sharing. The free plan costs nothing; Pro is $99 a year.
