What it does

Manuscript submission portals demand CRediT contributor role assignments under tight deadlines—usually as an unformatted, single-use checkbox grid per author with no reusable draft, no journal-specific styling, and no shareable proof for co-authors. Spreadsheets and static text snippets quickly break when author order shifts, ORCID iDs are added, or target journals expect distinct formatting styles.

CRediT Matrix Builder is a free browser workspace that unifies author metadata management, visual role matrix building, and journal-ready statement generation on one page. The Matrix tab pairs an Author List panel—supporting bulk line-separated input, ORCID iDs, institutional affiliations, equal contribution (#), and corresponding author (*) tags—with an interactive matrix covering all 14 NISO CRediT contributor roles. Article-type filters hide non-applicable columns for review manuscripts, while an optional degree-of-contribution toggle replaces standard checkboxes with Lead, Equal, and Supporting selectors.

The Export tab previews auto-generated CRediT statements in real time across six journal presets: Plain text, Markdown, PLOS ONE, Elsevier, Frontiers, and machine-readable JATS XML. Researchers copy formatted paragraphs to the clipboard, download structured CSV or JATS XML files, or generate a stateless permalink containing a UTC audit timestamp to share contribution records with co-authors before final manuscript submission.

Why researchers use it

  • Build a reusable contribution record early instead of scrambling at manuscript submission
  • Export journal-ready statements without reformatting for PLOS, Elsevier, or Frontiers
  • Share exact matrix states with co-authors via URL without creating user accounts
  • Download machine-readable JATS XML with ORCID and role tags for journal portals
  • Document equal-contribution (#) and corresponding-author (*) footnotes automatically
  • Embed UTC lastModified audit timestamps in exports to resolve potential authorship disputes

Best for

  • Corresponding authors preparing CRediT statements for manuscript submission
  • Lab leads assigning contributor roles at project kickoff rather than paper submission
  • Review articles requiring specialized CRediT role column subsets
  • Research teams needing structured CSV matrix exports for institutional CRIS platforms
  • Co-author review rounds where shareable permalinks replace static spreadsheet attachments

When to use this vs alternatives

Choose CRediT Matrix Builder when you need an interactive visual matrix with per-journal statement formatting, JATS XML export, and stateless permalinks. Use Safe Table Bio to clean author roster spreadsheets and normalize metadata before building your matrix.

What makes it different

Journal submission portals restrict CRediT role entry to single-use web forms with no export capability, visualization, or pre-submission sharing. Spreadsheet templates like Tenzing require template literacy and lack real-time sentence formatting or instant JATS XML generation.

CRediT Matrix Builder combines a visual author × 14-role grid, article-type column filters, 3-way contribution degree selectors, real-time journal statement rendering, and stateless URL hash state in a free browser app. Researchers switch when portal checkboxes create last-minute submission stress, co-authors disagree on unrecorded role contributions, or journals demand structured JATS XML files.

How to get started

  1. Open the workspace on the Matrix tab.
  2. Enter author names into the text area or click Add Author to build the list line by line.
  3. Expand author details to add ORCID iDs, institutional affiliations, or toggle Equal (#) and Corresponding (*) markers.
  4. Select an Article type filter (All 14 Roles, Review Article, or Empirical Study) and toggle Degree of contribution if needed.
  5. Click matrix checkboxes to assign roles; hover over column headers to view official NISO definitions.
  6. Switch to the Export tab, choose a Journal format, toggle the timestamped audit header, and click Copy Statement, Download XML, or Share Link.

Frequently asked questions

What are the 14 NISO CRediT contributor roles?
The tool implements the full NISO CRediT taxonomy: Conceptualization, Data Curation, Formal Analysis, Funding Acquisition, Investigation, Methodology, Project Administration, Resources, Software, Supervision, Validation, Visualization, Writing – Original Draft, and Writing – Review & Editing. Column headers display abbreviations (such as Concept. or Method.); hovering over any header shows the official NISO role definition.
How does the Review Article filter reduce matrix clutter?
Selecting Review Article hides laboratory- and software-specific columns (Data Curation, Funding Acquisition, Project Administration, Resources, Software, Supervision, and Validation) to show only the seven roles relevant to review manuscripts. Empirical Study and All 14 Roles display the full 14-role taxonomy. Column filtering simplifies matrix navigation without altering underlying author assignments.
What journal export formats are supported?
The tool generates statements for Plain text (standard sentences), Markdown (bold role titles), PLOS ONE (Author Contributions prefix), Elsevier (CRediT authorship contribution statement header), Frontiers (Author Contributions block), and JATS XML (<contrib-group> with <role> tags). Download CSV exports the full matrix, while Download XML generates valid JATS XML for direct publisher portal ingestion.
How does the shareable URL preserve matrix state without an account?
The entire workspace state—including author names, ORCID iDs, affiliations, contribution markers, cell assignments, degree levels, and a UTC lastModified timestamp—is serialized as JSON and base64-encoded into the URL hash (#state=...). Clicking Share Link copies a stateless permalink that co-authors can open in any browser to inspect or edit the exact matrix state.
Can I import an existing author list or CRediT file?
Yes. Click Import CSV/XML on the Matrix tab to upload existing files. CSV imports parse author names, ORCID iDs, affiliations, and role columns matching NISO terminology. JATS XML imports extract <contrib> elements, ORCID identifiers, and <role> tags into the visual matrix automatically.
Can I use an AI agent with CRediT Matrix Builder?
Yes. The built-in workspace assistant validates author entries, explains role definitions, and assists with statement formatting. External AI agents can call the tool programmatically via [API & MCP](/tools/developers) using tool ID pepkio_credit-matrix-builder to parse author text, construct matrices, or generate JATS XML within automated publication pipelines.
