How to Choose the Right Tool
Consider these factors when selecting a PRISMA flow diagram tool:
-
Do you need just the diagram or a full review platform? If you only need the flow diagram, a focused tool like our PRISMA 2020 compliant diagram generator is the fastest option. If you need screening, extraction, and collaboration, consider Covidence or Rayyan.
-
Budget constraints? For free options, our tool and the PRISMA2020 R Shiny app are the best choices with full PRISMA 2020 compliance.
-
Template enforcement: Tools that enforce the correct PRISMA 2020 structure reduce the risk of the common PRISMA diagram mistakes that lead to revision requests.
-
Export requirements: Most journals accept PNG or PDF. All tools listed above support at least one of these formats.
Frequently Asked Questions
Which PRISMA diagram tool is best for beginners?
Our free online PRISMA diagram generator is the most beginner-friendly option. It requires no installation, no signup, and provides a real-time preview with template enforcement that prevents structural errors. The AI Load Example feature helps you understand the expected data format.
Can I create a PRISMA diagram in Microsoft Word?
Yes, but it's not recommended. Manually drawing diagrams in Word is time-consuming, error-prone, and difficult to update. Dedicated tools produce better-quality diagrams in a fraction of the time.
Do any tools support PRISMA 2020 and PRISMA-ScR?
Most tools focus on standard PRISMA 2020 templates. Scoping reviews using PRISMA-ScR may require adapting the standard templates. See our guide on PRISMA-ScR for scoping reviews.
Is the official PRISMA2020 R Shiny app still maintained?
Yes, the PRISMA2020 R package is maintained by the Evidence Synthesis Hackathon team on GitHub. It receives periodic updates and supports all PRISMA 2020 template types.
