AI-rate reduction and natural-language polishing
This tool changes how a passage reads — sentence shape, word choice, rhythm. It does not rewrite your argument or add anything you did not write; the meaning and structure stay as they were.
An advanced mode runs as a background job, so long documents can be submitted and collected later from your history.
What it changes, and what it leaves alone
This feature changes how the writing reads — sentence shapes, word choice, rhythm. It does not rewrite your content or add anything you didn't write; the meaning and structure stay as they are.
Two ways to hand over the text
Paste the text directly and the result appears on the right, ready to copy or export as txt or docx. Or upload a file — txt, md, docx or pdf, up to 10MB each — and the text is extracted first, then rewritten. Advanced mode lets you pick several files at once, each becoming its own queued job.
About passing AI detectors
We can't promise this one, so here it is straight:
- Against detectors that read statistical signals — perplexity, sentence regularity — such as VIP and Chaoxing, it usually works.
- Against the strictest ones such as Tencent Zhuque and CNKI, and against Turnitin for English, results vary by text and we can't guarantee a pass.
- The rewrite only touches the surface of the language. Whether the content rests on real material is something people still read for.
- To be safer, go over the rewritten text yourself and add your own examples, data and judgement.
How the two modes differ
| Standard | Advanced |
|---|
| Rewrite method | One pass over the whole text | Paragraph by paragraph, two passes |
| Time to result | Seconds | About 2.8 minutes per 1,000 characters |
| Credits | 10 per 1,000 characters | From 250 per 1,000 characters |
| Per-run limit | 12,000 characters | 20,000 characters |
| Suits | Taking the AI edge off a draft, long texts, or hearing what the rewrite sounds like | A final draft you're handing in, or a text that still reads stiff after Standard |
Frequently asked questions
Is there a discount for members?
Members get their first article free; after that, and for free users from the first, standard mode is 10 credits per 1,000 characters.
Do I have to keep the page open for a long text?
No. After submitting on Advanced you can close the page — the job keeps running, and the result waits for you under History.
What is the cheapest way to use it?
Don't start a long text on Advanced. Run a section through Standard first, check the tone is right, then decide whether Advanced is worth it. Advanced takes up to 20,000 characters per run, so splitting by chapter goes through more reliably than forcing a whole book at once.
Does it work on English?
Yes, on both Chinese and English.
