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.
Systematicly
Systematicly is a web-based research platform for systematic reviews, primary research, ethics applications and research proposals. It can analyze a topic using PICO, PECO or SPIDER frameworks and produce Boolean searches for databases including PubMed, Scopus, Web of Science, ERIC and PsycINFO. Reviewers can screen titles and abstracts and upload PDFs for structured field extraction. Analysis options include 1,033 statistical functions, plain-English analysis, meta-analysis, plots, sensitivity analysis and GRADE assessment. The platform lists eight review types, plus publishing tools such as AI-assisted manuscripts and proposals, PRISMA diagrams, journal recommendations and reviewer response letters. It retrieves PDFs automatically from PMC, Unpaywall and EuropePMC, and supports ClinicalTrials.gov imports and several reference formats. The free Explorer plan is limited to three active personal drafts, one lifetime feasibility preview and three lifetime Evidence Answers. Paid one-time options include a single Evidence Answer for $19, paid once and literature review packages from $149, paid once. The security page says user data is not used to train AI models; Anthropic’s commercial API may retain inputs and outputs for up to 30 days for trust and safety monitoring.
