Abstrackr review
A free web tool for structured citation screening, team review, and PRISMA tracking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Abstrackr is a web-based citation-screening tool for researchers, librarians, and review teams conducting scoping or systematic reviews. It supports solo reviewers and collaborative teams through single, double, and pilot screening modes, blinded independent decisions, tagging, assignments, deadlines, reminders, and Member and Leader roles. The free plan includes citation screening, team collaboration, machine-learning prioritization, PRISMA reporting, and CSV, RIS, and JSONL export.
Its strongest fit is a structured screening workflow. Teams can import citations, use citation deduplication based on DOI and PMID, assign screening sets, and manage conflicts through automatic detection and leader resolution. Machine-learning ranking becomes available after approximately 100 labels, helping prioritize citations during screening. PRISMA numbers and exclusion-reason reporting support review documentation, while filtered citations can be exported as CSV or RIS and complete project data can be downloaded as JSONL.
Abstrackr is also notable for its free access model: the published product description states that it has no subscription, usage cap, or seat limit. That makes it suitable for teams seeking focused screening infrastructure without a paid tier. Its scope is narrower than tools that combine screening with full-text analysis, AI-generated summaries, or broader evidence-synthesis functions. Choose Abstrackr when citation and abstract screening, collaboration, conflict management, and PRISMA tracking are the priority; choose an alternative when full-text analysis or paper summaries are central requirements.
