Wordtune and QuillBot are the two leading paraphrasing tools. Wordtune leans on tone-shifting at the sentence level; QuillBot bundles more modes (formal, simple, fluency, etc.) plus grammar, summarizer, and citation. Neither ships AI detection. SynthQuery is included for users who need detection-aware rewriting in the same flow.
Wordtune for users who want a clean, fast sentence-level rewriter with tone control. QuillBot for users who want more modes plus grammar/summarizer/citation in one product. SynthQuery for users who also need AI detection on output (clients running detector checks).
