In their own words
Abstrackr
Abstrackr is a free web tool for screening citations in systematic reviews. It supports solo work, blinded team screening, pilot rounds, and conflict resolution. After about 100 labels, machine learning ranks remaining citations by predicted relevance. A live PRISMA flow table records screening thresholds, resolved conflicts, exclusion reasons by tag, and analysis of the model’s stop point. Citations can be imported from PubMed, Scopus, or Embase, or uploaded as RIS and CSV files. The service deduplicates records by DOI and PMID and can merge remaining near-duplicates. Results export as CSV or RIS, with a full JSONL download for DuckDB queries. Blinding starts enabled, and changes are logged with user, reason, timestamp, and project snapshots. Member and Leader roles have no stated team-size limit, while reminders arrive 7, 4, and 1 day before deadlines. No installation is needed, and the site directs methodology questions to its community forum.
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.
