What Is an AI Detector (English)?
An AI detector estimates whether a passage was likely written by a human or generated by an AI model. This page uses an offline, heuristic approach—no external APIs—so analysis is fast, private, and free. It’s useful for quick screening of essays, emails, blog posts, and marketing copy.
How This English AI Detector Works
Our heuristic engine analyzes writing style and surface statistics often associated with machine-generated text. It does not read your content for meaning; it measures patterns. Key checks include:
- Sentence uniformity & burstiness: Very even sentence lengths can be a sign of templated output.
- Repetition patterns: Frequent bigram/trigram reuse suggests boilerplate phrasing.
- Type–Token Ratio (TTR): Low lexical variety in longer passages can look AI-ish.
- Stock connectors: Phrases like “in conclusion,” “moreover,” “furthermore” may appear in AI drafts.
- Colloquial markers: Human writing often includes light informality (e.g., “kinda,” “gonna,” “you know”).
The tool returns a probability-style label (Likely Human, Mixed/Uncertain, Possibly AI) plus a mini report of the metrics it used.
When to Use It
- Educators & students: Sanity-check drafts before submission.
- Content teams: Spot overly formulaic copy before publishing.
- Editors & reviewers: Prioritize pieces that need human polishing.
Tips to Improve Accuracy
- Analyze at least 200–300 words for more stable signals.
- Avoid pasting lists of bullets only; include full sentences and paragraphs.
- Run multiple samples (intro, body, conclusion) for a broader view.
Privacy & Limitations
- Offline by design: Your text is processed locally on this site; no GPT calls.
- Heuristic, not forensic: Results are guidance, not proof. Use judgment and context.
- Style matters: Very formal human prose can look “AI-ish,” and polished AI can look human.
What to Do with “Possibly AI” Text
If a passage scores “Possibly AI,” try rewriting with our Humanize AI English tool to add variety, clarity, and a more natural tone. Need detection in Filipino? Use AI Detector Tagalog.
FAQs
Is this 100% accurate?
No. It’s a probability estimate based on writing patterns. Treat it as a signal, not a verdict.
Does it store my text?
No. The detector runs without external API calls and does not save your content.
Will longer text help?
Yes—longer samples (200–500+ words) usually produce more reliable signals.
