wordtune was one of the first ai rewriting tools. it launched before chatgpt blew up, back when "ai writing assistant" meant sentence-level suggestions. it's a good tool for what it does.

the problem is what it doesn't do.

how wordtune works

you highlight a sentence. wordtune gives you alternatives. pick one, move on to the next sentence. repeat.

it's like having someone look over your shoulder and say "hey, you could also phrase that like this." useful when you're polishing a paragraph or trying to find a better way to say something specific.

the rewrites are decent. often more concise or clear than the original. for regular editing, it works.

the sentence-level problem

ai detectors don't look at individual sentences. they look at patterns across the whole text. the rhythm of your writing. how sentence lengths vary. how vocabulary is distributed across paragraphs.

rewriting one sentence at a time doesn't fix these patterns. you might improve each sentence individually but the overall texture stays the same. it's like repainting each room in a house a slightly different shade of beige — step back and it still looks beige.

wordtune also can't see context beyond the sentence it's rewriting. it doesn't know that the previous three sentences all started the same way or that your last five paragraphs are all the same length. those are the patterns that get you flagged.

how paraai handles full-text rewriting

paraai's paraphrase tool works on the whole passage at once. it's built on fine-tuned sota models trained on human-text corpora, so it understands how real writing flows across paragraphs — not just within a single sentence.

when you run a block of text through paraphrase, it restructures the whole thing. long sentences get broken up. short sentences get combined. the overall rhythm changes. word patterns shift. the result reads like a different person wrote it, not like the same person used a thesaurus.

that's the difference between sentence-level and passage-level rewriting. one fixes words. the other fixes patterns.

the workflow gap

wordtune is an editing overlay. you still need to write the initial draft somewhere else, and you still need to go sentence by sentence to rewrite.

paraai gives you the whole workflow. cowrite for first drafts. quill for real-time editing. paraphrase for full-text rewriting. you go from idea to untraceable ai output without switching tools or working sentence by sentence.

when wordtune makes sense

if you're editing your own human-written text and want suggestions for individual sentences, wordtune is solid. it's a good editing companion.

if you're working with ai-generated content and need the whole thing to pass detectors and sound natural, you need passage-level rewriting. that's paraai.
