This checker measures writing-style signals. No tool, including Turnitin, can prove who wrote a text, so treat the score as a guide to revise your writing, not as evidence.
How the AI checker works
Paste at least 80 words. The checker looks at four writing-style signals that are much more common in AI-generated text than in student writing:
- Sentence variety. People naturally mix short and long sentences. AI text is often very even.
- AI-style phrases. Words such as "delve", "pivotal", "tapestry" and "it is important to note".
- Formulaic openers. Many sentences starting with "Furthermore", "Moreover" or "Overall".
- Dash use. Frequent dashes are a common AI habit.
It then shows a score, the signals behind it and the sentences worth revising. Everything runs in your browser, so your text is never uploaded.
What the score means
| Score | Result | What to do |
|---|---|---|
| 0–34% | Mostly human-like | Check the flagged sentences, if any |
| 35–59% | Mixed signals | Revise flagged sentences and vary sentence length |
| 60–100% | Strong AI-style signals | Rewrite in your own voice, with your own examples |
No detector can prove authorship
AI detectors, including the ones universities use, look for patterns. They can flag human writing, especially from non-native English speakers, and they can miss edited AI text. Use this score to improve your writing, not as proof either way.
How to make your writing sound like you
- Use specific examples from your course, your reading or your own experience.
- Vary sentence length: follow a long, detailed sentence with a short one.
- Replace generic transitions with sentences that explain the link between ideas.
- Show critical judgement: say which evidence is stronger and why. Our guide on how to write critically shows how.

Frequently asked questions
- Is this AI checker accurate?
- It's a guide, not a verdict. It measures style signals that are common in AI text, but no detector can prove who wrote something. Use it to find sentences to revise.
- Is my text uploaded or stored?
- No. The checker runs entirely in your browser, so your text never leaves your device.
- Does it work like Turnitin's AI detection?
- No. Turnitin uses its own trained model, and we can't predict its results. Both tools look for patterns, and both can be wrong.
- Why was my own writing flagged?
- Formal academic writing can share some features with AI text, especially formulaic transitions and very even sentences. Revising those makes your writing clearer as well.
