Elsevier, Springer, Nature, IEEE and Wiley all require AI disclosure, but they do not agree on where the statement goes or what counts as exempt. Here is what each publisher's own policy actually says, quoted directly, publisher by publisher.
An abstract is the most-read and least-carefully-drafted paragraph in academic writing. Here is the skeleton editors and reviewers actually expect: one sentence for context, one for the gap, one for method, result and implication, plus a before-and-after rewrite.
