Frequently Asked Questions
Common questions about using DocxDetector for Turnitin reports:
Why doesn’t DocxDetector index my papers?
Our Turnitin account is configured to never store submitted papers—no matter how many times you check.
What does % mean in the AI report?
After July 16, 2024, Turnitin displays *% for AI proportions between 1%-19% due to estimation uncertainty. Exact values shown for 0% or ≥20%. A *% result is typically acceptable if your school doesn’t require 0% AI.
Are DocxDetector’s AI results consistent with my school’s Turnitin?
If content matches exactly, results should align. Edits (grammar, wording) after checking may cause discrepancies. Always recheck after revisions.
Is the reference list included in the similarity score?
No. Reference lists are excluded by default—matching most academic standards.
Why is Turnitin’s AI score low but GPTZero’s high?
Turnitin uses strict thresholds to avoid false positives. Schools aim to discourage full AI reliance—not penalize partial use.
Why did my AI report fail to generate?
Possible reasons: non-supported language or word count outside 370–28,000. If not, try resubmitting.
Can I use DocxDetector if my paper is already in my school’s Turnitin?
Yes, but expect a high similarity score. AI detection remains unaffected.
Why am I flagged for AI if I didn’t use ChatGPT?
AI detectors (including Turnitin) aren’t perfect. Tools like Grammarly or Quillbot can trigger flags. Simplify overly formal phrasing to reduce risk.
Why do unflagged sections become AI-flagged after edits?
AI detection analyzes the entire document’s context—not isolated sections. Revisions can shift the AI probability across the text. Example: Sam’s 1,000-word paper had Part C flagged. After editing Part C, Part A (previously clean) became flagged. AI detection is holistic—always recheck after edits.
What languages does DocxDetector support?
Similarity reports: 176+ languages (English, Chinese, Spanish, German, etc.). AI detection: English, Spanish, Japanese only.
What if I miss the 24-hour download window?
Reports auto-delete after 24 hours for privacy. Download promptly—or check your email; we send a copy there.
Will my 0% AI score stay 0% forever?
Turnitin updates its AI model periodically. Past 0% results may change in future scans—but won’t affect already-submitted assignments.
