AI text detector
Free AI Detector for UK Students and Educators
AI detection that starts a review, not a verdict: check English prose for AI-writing signals, understand the result, and keep a person responsible for every conclusion.
Free preview
Paste your text to check it for AI signals
No sign-up needed. Your text is analysed, then discarded — it is never stored or used for training.

See the document-level signal before creating an account
The public preview is deliberately narrow: it offers a quick AI-only result without presenting that result as proof.
English text from 300 characters
Paste continuous English prose. Very short samples cannot be submitted because they provide too little context for the current workflow.
Up to 350 words
The free preview analyses a short sample and returns one overall AI score and label. It does not include sentence-level results.
Two previews per day
The public scan is rate-limited by a privacy-preserving hash of the network address used for the request.
AI detection only
Plagiarism source matching is available after sign-in as an optional mode in a paid scan, not in the free preview.
Full review
Move from a headline score to inspectable context
A paid scan uses one credit and can analyse a longer document with a sentence-by-sentence breakdown.
- 01
Paste text or upload a readable PDF
PDF text is extracted in the browser. Image-only or scanned PDFs need optical character recognition elsewhere before they can be checked.
- 02
Choose AI only or AI plus plagiarism
The same scan-credit workflow lets you choose whether to add source matching. The two results remain separate because they answer different questions.
- 03
Review the passages
Paid results include sentence-level AI signals where the analysis provider returns them, alongside the overall score and label.
- 04
Keep a report if needed
The full breakdown is kept temporarily in the current browser session. You can email yourself a copy before closing the tab.
Interpretation
What Genutext's current labels mean
The displayed percentage is an AI-writing signal on Genutext's scale. It is not the probability that a person cheated.
| Displayed range | Label | Responsible reading |
|---|---|---|
| 0–29 | Likely Human | The analysed text showed fewer AI-like signals, but a low score does not prove human authorship. |
| 30–59 | Mixed Content | The result is not conclusive. Review the highlighted passages, writing process, task and permitted assistance. |
| 60–100 | Likely AI Generated | The text showed stronger AI-like signals. Treat this as a reason to review, not as a disciplinary finding. |
Data handling
Submitted text is processed, then discarded
Genutext is designed so the writing itself is not retained in the scan history.
The service sends submitted text to its analysis provider to produce the result. Genutext stores scan metadata and score summaries for account history, but not the submitted text or the detailed passage breakdown.
The detailed paid result is temporarily held in browser session storage. An emailed report is the option for keeping a full copy. Review the privacy policy before submitting student work, confidential material or personal data.
Common questions
AI detector FAQ
- Is this AI detector free?
- Yes. The free preview checks 300 characters to 350 words of English text once per day, with no sign-up. Creating a free account includes your first full scan of up to 3,000 words.
- How accurate is the AI detector?
- No AI detector is 100% accurate, including this one. Genutext publishes its methodology and limitations and presents every score as a signal for human review, not proof of authorship.
- Do I need to sign up to check my text?
- No. The on-page preview runs without an account. An account unlocks full-length scans, sentence-level results, PDF upload, optional plagiarism checking and an emailed report.
- Is my text stored or used to train AI models?
- No. Submitted text is processed for the report and discarded. It is not stored or used for training.
- Will my score here match Turnitin's score?
- No. Turnitin uses its own model, thresholds and text-eligibility rules, so no third-party detector can predict a Turnitin result. Use this check to understand your own writing, not to chase a number.
