WHAT IT IS

What are PRISMA Charts?

PRISMA Charts is a PRISMA flow diagram generator: it builds a PRISMA 2020 flow diagram and the full 27-item reporting checklist as editable artifacts, with the identification counts auto-filled from your search. You make the screening and inclusion decisions. CoChat draws the diagram, tracks the checklist, and keeps the counts consistent.

PRISMA is the reporting standard for systematic reviews, and the flow diagram is the figure every reviewer looks for first. Building it by hand is the part nobody enjoys: a maze of boxes and arrows redrawn in PowerPoint every time a screening number changes, plus a 27-item checklist tracked in a separate document.

CoChat turns both into live artifacts. The diagram covers all four PRISMA 2020 template variants, renders from your counts, updates when the numbers change, and exports as SVG, PNG, or print-ready PDF. The checklist sits alongside it, pre-seeded with all 27 items (42 rows), ready for you to mark each one reported, not reported, or not applicable, and exports as CSV or Markdown.

HOW IT WORKS

From counts to publication-ready figure

Bring your search, screen and triage, generate the diagram, edit it in form or split view, track the 27-item checklist, export.

THE WORKFLOW IT UNLOCKS

The diagram is not the end of the review.
It travels with it.

A PRISMA figure is not a one-time export. It is a living record of how the review was built, and it changes as the review does.

Your screening decisions become the counts in the diagram. Those same counts feed the checklist, so the figure and the reporting stay consistent instead of drifting apart in two documents. When a reviewer asks you to re-run a search or re-screen, you change the number once and the diagram redraws itself. And because the flow lives in the same workspace as your paper search, your literature review table, and your citation checks, the whole review stays in one place from first search to final figure.

SEE THE RESULT

One search, one standards-compliant figure

The figure a reviewer looks for first, generated from your counts and laid out to the PRISMA 2020 standard, with the checklist tracking alongside it.

WHY COCHAT

Built to the actual PRISMA 2020 standard, and it lives where your review does.

PRISMA is not a loose convention. It is a published reporting standard, and journals hold submissions to it: the flow diagram with its identification, screening, and included arms, and the 27-item checklist that documents how the review was conducted. Get the figure wrong and a reviewer notices immediately.

The bar is real, and most reviews still fall short of it.

60,000+

citations, and endorsed by nearly 200 journals

80+ a day

systematic reviews published as of 2019, a 20-fold rise since 2000

30% / 42.64%

of post-2020 reviews cited PRISMA 2020; average adherence 42.64%, none fully compliant (2024 study)

CoChat generates both to the PRISMA 2020 standard, as editable artifacts rather than static images. That matters because the numbers change: a reviewer asks you to re-run a search, screening shifts, and a hand-drawn diagram means starting the figure over. Here you change the count and the diagram redraws itself. And because PRISMA Charts live in the same workspace as your paper search, your literature review table, and your citation verification, the whole review stays in one place from search to reporting.

FAQ

Frequently asked questions

1. Can CoChat generate a PRISMA flow diagram?
Yes. CoChat generates a PRISMA 2020 flow diagram as an editable artifact, laid out to the standard with identification, screening, and included arms. Your counts populate the boxes, and the diagram updates when the numbers change. Export it as a publication-ready figure.
2. Does it include the PRISMA checklist too?
Yes. The full 27-item PRISMA 2020 checklist comes pre-seeded. You mark each item as reported, not reported, or not applicable, and note where it appears in your manuscript.
3. Does CoChat do the screening for me?
No, and that is by design. You make every inclusion and exclusion decision. CoChat draws the diagram, holds the checklist, and keeps the counts consistent. The methodological judgment stays with you.
4. What happens when my screening numbers change?
You update the count and the diagram redraws itself. No rebuilding boxes and arrows by hand. This is the main reason to generate the figure rather than draw it in PowerPoint.
5. Can I export the diagram for publication?
Yes. Export the flow diagram as SVG, PNG, or print-ready PDF, and the checklist as CSV or Markdown, ready for journal submission.
6. Does it work with CoChat's paper search?
Yes. PRISMA Charts live in the same workspace as paper search across CrossRef, OpenAlex, PubMed, arXiv, Semantic Scholar, CORE, and DOAJ, plus citation verification, so your whole review stays in one place from search to reporting.
