CRediT author contribution statement generator
Add each author, tick what they did from the 14 CRediT roles, and get the author contribution statement in the format Elsevier, Wiley, Springer Nature and many other publishers ask for. Copy it into your manuscript. No account needed.
CRediT (Contributor Roles Taxonomy) is a NISO standard (ANSI/NISO Z39.104-2022). Each author’s roles should be agreed by all authors before submission.

Add each author’s name and tick their roles to see the statement.
How the statement is built
The generator lists each author followed by their roles, in the taxonomy’s order, one sentence per author. That is the format on Elsevier’s sample statement. It does not use an AI model, and nothing you type leaves this page.
The 14 CRediT roles (checked 22 October 2026)
Conceptualization, Data curation, Formal analysis, Funding acquisition, Investigation, Methodology, Project administration, Resources, Software, Supervision, Validation, Visualization, Writing – original draft, and Writing – review & editing. The definitions are on the NISO CRediT site. Elsevier’s CRediT author statement page has the sample format this tool follows.
Frequently asked questions
Which journals require a CRediT statement?
Most Elsevier and Cell Press journals, PLOS, Wiley, Springer Nature, and many society journals either require it or accept it as the author contribution statement. Check the author guidelines; some journals collect roles in the submission system instead of the manuscript.
Can two authors share a role?
Yes. A role can be assigned to as many authors as it applies to, and an author can have several roles. Some journals also let you add “lead”, “equal” or “supporting” to each role; add that by hand if yours does.
Where does the statement go?
Usually after the acknowledgements or just before the references, under a heading such as “CRediT authorship contribution statement” or “Author contributions”. Follow your journal’s template.
What is the difference between Investigation and Formal analysis?
Investigation is doing the research: running experiments, collecting data or evidence. Formal analysis is applying statistical, mathematical or computational techniques to analyse that data.
Does writing the code count as Software?
Yes. Software covers programming, developing and testing code and algorithms, including reusable components used in the study.
