PRISMA Flow Diagram Generator

All four official PRISMA 2020 templates, live preview, and export to SVG or PNG. Free, no account.

It also checks your arithmetic. Most generators draw whatever you type, including a funnel that cannot be true. This one reconciles every stage against the ones around it and tells you which number is wrong — including whether your exclusion reasons add up to your exclusions, which is the check a reviewer does by hand.

Unsure what a method term means? The research terminology defines the vocabulary these tools use, in plain language. Or see the tools used end to end on a real question.

This diagram is drawn from numbers you typed.

That is fine, and it is what every free generator does — but nobody, including you, can check a typed number later. In the research workspace the same figure is COUNTED from your actual screening decisions, each one logged with a reason in a record that cannot be edited afterwards. Same diagram, except you can answer for every box in it.
