Read Before Checking

To ensure accurate results from Turnitin’s official system, please review the requirements below. Plagiarism and AI detection have different criteria.

  • File Size: Under 100MB
  • Minimum Words: At least 20 words of text
  • Accepted Formats: .docx, .pdf
  • Supported Languages: 176+ languages, including English, Chinese, Spanish, French, German, Japanese, etc.
  • Important Limitations:
    • Check is not supported for PDFs containing scanned images or non-selectable text.

AI Writing Detection

Analyzes your text to identify content likely generated by AI tools like ChatGPT.

  • File Size: Under 100MB
  • Minimum Words: At least 300 words of continuous prose (no lists or code)
  • Maximum Words: Up to 30,000 words

Frequently Asked Questions

Common questions about using DocxDetector for Turnitin reports:

If content matches exactly, results should align. Edits (grammar, wording) after checking may cause discrepancies. Always recheck after revisions.
Our Turnitin account is configured to never store submitted papers—no matter how many times you check.
Similarity reports: 176+ languages (English, Chinese, Spanish, German, etc.). AI detection: English, Spanish, Japanese only.
Most reports are ready in 3-15 minutes. During peak times (finals week, end of semester), it may take up to 30 minutes. You'll receive an email notification when your report is ready.
Yes! We use official Turnitin educator accounts configured for no storage. The report you receive is identical to what your professor or institution sees—same database, same AI detection, same similarity scoring.
We accept PDF and DOC/DOCX files (max 20MB). Word count requirements: 300-30,000 words for similarity check, 370-30,000 words for AI detection. Documents outside these ranges may not generate accurate reports.
Possible reasons: non-supported language or word count outside 300–30,000. If not, try resubmitting. Failed credits are automatically refunded.
No. Reference lists are excluded by default—matching most academic standards.
Turnitin uses strict thresholds to avoid false positives. Schools aim to discourage full AI reliance—not penalize partial use.
Yes, but expect a high similarity score. AI detection remains unaffected.
AI detectors (including Turnitin) aren’t perfect. Tools like Grammarly or Quillbot can trigger flags. Simplify overly formal phrasing to reduce risk.
AI detection analyzes your entire document holistically. When you edit one section, it can change the AI probability of other sections. That's why we recommend rechecking after major revisions to get updated results.
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.
Reports auto-delete after 24 hours for privacy. Download promptly from your <a href="/dashboard/turnitin-record" class="text-blue-600 hover:underline">detection history</a>, or check your email—we send a copy there.
Turnitin updates its AI model periodically. Past 0% results may change in future scans—but won’t affect already-submitted assignments.
