PaperMirror tutorial: scan, one-click rewrite, retest

TL;DR Sign up for 1,000 credits → upload or paste → read the overall rate and red paragraphs → one-click rewrite on high-risk bands → retest → read it yourself. Detection is 1 credit/character; rewrite is 2 credits/character.

Domestic “lower AI” sites all ship a long “from signup to success” guide. PaperMirror’s path is shorter because scan and rewrite live on the same report. You do not pick “CNKI mode / VIP mode.”

0. Prepare

  • Latest .docx or plain text. Save PDFs to Word first.
  • 20,000 characters per run; skip scans under 200 characters.
  • Sign up for 1,000 credits, or try 1,000 characters on the homepage without an account.

1. Scan

  1. Open Start a scan.
  2. Paste or upload, confirm the estimated credit use.
  3. Wait for MirrorEngine to score paragraphs.
  4. Read the dashboard overall rate plus high / medium / low colour.

2. One-click rewrite

Only touch red paragraphs. Rewrite is 2 credits/character. Compare with the original: terms, numbers, citations still there? Locally rewrite any sentence you cannot read.

3. Retest

Score again on the same engine. Aim: overall rate in the low-risk band, continuous red gone. Do not declare victory on ZeroGPT.

4. Before you submit to school

  • Read it aloud. The argument still holds.
  • Follow school policy on disclosing AI-assisted polish.
  • Official submit still goes through Turnitin or CNKI (China’s academic database / AIGC checker).

The tutorial takes a few minutes

If credits run out, buy the ¥30 pack. You only pay for what you use.

Detection and rewrite are for pre-submit self-checks. Follow your school's integrity policy. PaperMirror is not Turnitin or CNKI. The school system is the source of truth.
