claude might be the best general-purpose ai for writing. the prose is cleaner than chatgpt. the tone is more natural. it follows instructions better and produces less formulaic output.

it still gets flagged by every ai detector.

why claude is good at writing

anthropic trained claude with a focus on helpfulness and nuance. the result is an ai that writes with more variation than chatgpt. it uses fewer filler phrases. the paragraph structure is less rigid. it's genuinely better at matching requested tones.

if you had to pick one ai model for raw writing quality, claude is probably the answer.

why it still gets caught

better writing isn't the same as human writing. claude's output has lower perplexity than chatgpt — slightly more varied word choices — but the overall statistical signature is still ai.

detectors don't just look for chatgpt patterns. they look for any text where the word distributions and sentence patterns match machine generation. claude's generation process is different from chatgpt's but it's still a language model predicting tokens. the fundamental pattern is there.

we've tested it. raw claude output scores 75-90% ai on most detectors. better than chatgpt's 90-99%, but still clearly flagged. originality.ai catches it reliably.

the gap paraai fills

claude is a great starting point. better raw material means less work for the rewriter.

take a claude draft, run it through paraai's paraphrase. the fine-tuned models restructure the already-decent prose into genuinely human-sounding text. because claude's starting quality is higher, the paraphrased output is often excellent — natural, well-written, and completely undetectable.

the best combo?

honestly, claude + paraai might be the best workflow for pure output quality. claude produces the highest-quality ai drafts. paraai transforms them into the highest-quality human-sounding text.

cowrite is faster for getting started. but if you have claude access and want to maximize quality, drafting in claude and finishing in paraai's paraphrase is hard to beat.

either way, the untraceable ai output at the end is what matters. the draft source matters less than the final rewriting step.
