CNKI AIGC pass line: how to prepare for 20% / 15% / 10% on a 2026 master’s thesis
TL;DR Ask your adviser for the faculty file. Do not trust a nationwide 20%. In practice prepare against 20 / 15 / 10. Passing similarity is not passing AIGC. PaperMirror’s Chinese engine is for labelling, editing, and retesting red paragraphs before CNKI. The school CNKI report is still the source of truth.
Search “CNKI AIGC pass line” and you get stacks of 20% / 15% / 10% roundups. The structure is the same: a three-tier table, how to read the report, then a lower-AI tool. We follow that path with PaperMirror: in-house MirrorEngine, three-colour paragraphs, one-click rewrite then immediate retest. CNKI here means China’s academic database and its AIGC checker — keep the Chinese product name.
Three pass lines (faculty file first, blogs second)
| Band | Common rule | Who uses it | How to leave margin in a self-check |
|---|---|---|---|
| Looser | Overall suspected-AI < 20% | Most ordinary master’s programmes | Get PaperMirror into the low-risk band, then submit to school |
| Tighter | < 15% | Some 985/211 or strict faculties | Clear the red band. Do not gamble at 18% |
| Strictest | < 10% | A few faculties in writing | Put your own operations in methods / discussion; fewer template review sentences |
When there is no faculty memo, prepare at under 15% plus no continuously highlighted chapters. That is safer than sitting on 19%. Undergraduate coursework is often looser; still self-check first.
AIGC and similarity are two different numbers
- Similarity: match against published literature and student corpora.
- AIGC: whether sentences look model-written. Similarity 8% and AIGC 45% can coexist.
- References, formulae, and code blocks are handled differently across systems. Do not read an AI rate off a similarity report.
How to read the report
- Overall suspected-AI rate first.
- Then chapters: literature review and conclusion go red most often.
- 0–10% usually clears; 10–20% depends on the school; 20–40% almost always needs edits; 40%+ must be treated.
If you are over the line (actionable)
- If the school only gives 1–2 official scans, finish the red band in PaperMirror first.
- Hit high-risk paragraphs only. Do not wash terms and data across the whole file.
- One-click rewrite, then retest in place.
- Read it yourself, then submit to school CNKI.

Chinese and English auto-detected. Detection billed per character; rewrite is double. Not an official CNKI report.

- No. The value is locating filler paragraphs you can rewrite and retest. The final reading is school CNKI.
- Do undergraduates have to pass AIGC too?
- More courses require it. With no memo, prepare under 20%.
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.
