Final recommendation

Compare Avellio, InDesign Preflight, GREP Find/Change, and human proofreading by task.

The most mature workflow is not “Avellio versus Preflight versus GREP versus people.” It is a sequence in which:

  • Preflight protects the output contract;
  • Avellio protects typography and style-system attention;
  • GREP executes known repeatable rules;
  • humans decide what the publication means and whether it is ready.

That division makes each tool more useful and makes the limits of every result visible.
