Two tools, two release questions.

Practical comparison / PMC and JATS

PMC Style Checker and JATS Verify solve different problems.

Use the official PMC checker for PMC-specific style rules. Use JATS Verify before delivery when you need to inspect the complete package, repeat journal rules, compare releases, and retain evidence.

Do not replace the destination's own checker.

The PMC Style Checker is free and authoritative for its stated PMC checks. JATS Verify does not certify or guarantee PMC acceptance.

A sensible release sequence

  1. 01
    Build the package

    Create the JATS XML and collect every locally referenced figure, media file, supplement, and related asset.

  2. 02
    Run package QA

    Use JATS Verify for structure, assets, internal links, identifiers, journal rules, changes, and retained evidence.

  3. 03
    Run the destination checker

    Use the current checker supplied by PMC, SciELO, your archive, or the receiving journal.

  4. 04
    Keep both results

    Retain the destination response and the package evidence with the exact release delivered.

Why pay for another check?

JATS Verify is useful when production teams repeat the same package review across suppliers, journals, and releases. The paid value is complete findings, reusable journal rules, release-to-release comparison, evidence downloads, and API execution. If the free PMC checker fully answers your release question, keep using it.
