What they do

Beyond basic spell-check, these tools flag awkward phrasing, inconsistent tone, and passive-voice overuse, then suggest edits that preserve the author's intent.

How they differ from grammar checkers

Modern versions use an LLM to understand meaning, not just pattern-match grammar rules, which lets them catch issues classic rule-based checkers miss — like a sentence that's grammatically fine but confusingly structured.

Where they fit

Ideal as a final polish pass on drafts already substantively complete, catching the kind of small inconsistencies that are easy to miss after multiple rounds of editing.
