In their own words
Covexe
Covexe is a browser-based platform for systematic reviews, meta-analysis, evidence synthesis, and applied statistics. Its review workflow spans question and search, screening, full-text review, extraction, appraisal, synthesis, and reporting. It supports 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 will not exclude a study without user approval. Signed-out work stays in the browser; signed-in reviews are stored for cloud sync and sharing. The free plan costs nothing, while Pro costs $99 a year. Team costs $150 a year per seat with a three-seat minimum.
ReviewAid
ReviewAid is a free, open-source AI tool for full-text screening and data extraction in systematic reviews. Researchers can provide PICO inclusion and exclusion criteria for classifying papers, then define which fields they want extracted. The tool reports confidence scores and marks low-confidence results for manual review. Downloads are available as CSV, XLSX, or DOCX. ReviewAid supports OpenAI, Anthropic, DeepSeek, Cohere, Z.ai, and local Ollama. When a cloud provider is selected, paper text is sent to that provider for the run; with Ollama, inference takes place on the local machine and the text remains there. The maker says API keys are not stored. Users can work in a browser-based Streamlit app or install locally with Python 3.12 or later and Streamlit on Windows, macOS, or Linux. Hosted sessions may take about 30 seconds to initialize. Submission guidance caps full-text screening at 10 articles and extraction at 20 per submission. ReviewAid is licensed under Apache 2.0 and is described as a supplementary reviewer, not a substitute for manual screening or extraction.
