Detect AI Writing: Review Academic Papers
Review AI-typical phrasing before submission with a sentence-level AI writing pre-check. It does not identify the model used or prove authorship. Results in about 15 minutes, from $0.29/page.
This multifaceted approach enables a comprehensive understanding of the topic.
Illustrative example, not an actual report. A score is not the probability that AI wrote a passage.
How Universities Are Responding to AI Writing
AI writing tools have spread so fast that academic institutions worldwide are overhauling their policies.
Updated Integrity Policies
Institutions set their own rules for permitted AI use and disclosure. A detector cannot establish compliance. Read your institution's policy before submitting.
Dedicated AI Detection Tools
Institutions are investing in tools to detect AI writing that go beyond traditional plagiarism checking. These tools analyze statistical text properties. Our PlagAware-powered detector lets you run an AI check on your own paper before you submit.
Proactive Student Responsibility
Follow your institution's requirements for independent work and disclosure. A detector cannot verify original thinking or compliance.
How to Detect AI Writing in 3 Steps
Upload Your Document
Submit your academic paper as .docx, .pdf, or .txt. Files are processed on German servers and never added to any public database. No account required.
AI Writing Analysis
PlagAware evaluates the frequency and relevance of stereotypical AI expressions in each sentence. The result measures AI-typical phrasing, not who wrote the text.
Actionable Report
Receive a PDF in about 15 minutes with sentence-level AI typicality from 0 to 100, with 50 neutral. Inspect highlighted patterns in context; they are not proof of AI use.
AI Writing Tools and Detection Limits
The detector assesses AI-typical phrasing rather than identifying a particular model. Detection is not guaranteed for every model, version, or edited passage. PCO has not published model-specific validation for this service.
- ChatGPT (GPT-3.5, GPT-4, GPT-4o)
- Claude (Anthropic)
- Google Gemini (Pro and Ultra)
- Meta Llama (2 and 3)
- Mistral, Phi, Falcon and emerging models
A report does not identify the model used. No score can confirm or rule out AI involvement reliably.
Overuse of "comprehensive"
Certain expressions occur more frequently in AI output, but human writers can use them too. No isolated phrase proves AI use.
Perfect paragraph structure
Both human writing and AI output can use regular paragraph structures. Structure alone does not prove authorship.
No grammatical errors
Correct grammar is not evidence of AI use. Human writers can write accurately, and AI output can contain errors.
The AI Writing Detection Score: 0 to 100
PlagAware measures AI typicality from 0 to 100 for each sentence, with 50 neutral. Lower values indicate less AI-typical phrasing; higher values indicate more AI-typical phrasing. The score is not an authorship probability or proof of AI use.
Below 50: Less AI-typical
Below 50 indicates less AI-typical phrasing. It does not prove human authorship or guarantee that AI use will not be flagged.
50: Neutral
50 is neutral: the phrasing occurs equally in natural and AI-generated text. It does not measure the degree of AI assistance.
Above 50: More AI-typical
Above 50 indicates more AI-typical phrasing. Human writing can also score high; review the passage in context.

Detect AI Writing: Frequently Asked Questions
Institutional practices vary. AI detectors assess language patterns rather than source matches. PlagAware evaluates the frequency and relevance of AI-stereotypical expressions at the sentence level.
No. A detector score does not establish compliance. Follow your institution's rules on permitted AI use, disclosure, citations, and independent work.
Academic institutions have adopted widely varying approaches. Some prohibit all AI use in assessed work. Some permit AI for research and editing but not for generating text. Some require disclosure of AI use. Policies are evolving rapidly. The safest approach is to check your institution's policy and, if in doubt, run a detection check on your paper.
The detector can miss AI-generated text and flag human writing. Model choice, prompts, editing, and subject-specific language can affect the scores. Review passages in context and follow your institution's AI policy. A low score does not rule out AI use.
PlagAware measures AI typicality from 0 to 100 for each sentence, with 50 neutral. Lower values indicate less AI-typical phrasing; higher values indicate more AI-typical phrasing. The score is not an authorship probability or proof of AI use. Review flagged passages in context, keep drafts, and follow your institution's policy.
