How this article rewriter works
This runs a synonym-substitution engine across a full multi-paragraph article at once, keeping every paragraph break exactly where it was. It swaps eligible words for close synonyms from a built-in dictionary at the strength you choose, and reports what share of words actually changed.
Why full-article processing matters here
Running the substitution across an entire multi-paragraph article in one pass, rather than one paragraph at a time, means word-choice variety stays natural across the whole piece - the same word appearing in different paragraphs can land on a different synonym each time, rather than every instance in a shorter single-paragraph tool getting the identical treatment independently.
Why it only touches word choice, never structure
It preserves your structure because it only touches word choice, never sentence order or paragraph layout. This is a deliberate, narrow scope - a tool that also reordered sentences or restructured paragraphs would risk changing meaning or flow in ways a word-level swap can't, so this stays limited to the one transformation it can do reliably and predictably.
Reading the changed-words percentage
The reported percentage reflects how many words in your text actually had an eligible synonym in the built-in dictionary and were swapped at the chosen strength - it's a direct, literal count, not an estimate of how "different" the piece reads overall, since a handful of well-chosen substitutions can change the feel of a passage more than a larger number of minor ones scattered throughout.
