AI Article Detector

What this tool does

AI Article Detector looks at the draft you paste and reports sentence length, how much those lengths vary, how wide the vocabulary is, and which short phrases repeat. The heading on the result is Writing pattern analysis. That is the whole claim.

How to use

1. Paste at least 40 words.
2. Press Analyze writing for the browser check, or Analyze with AI for a Gemini writing-pattern analysis.
3. Read the counts and the note under them.
4. If the sample is too short, the page says so instead of scoring it.
5. Clear removes the text from the page.

Examples

• A draft that repeats itself

  If the same four words appear in several sentences, they show up in the list with a count. That means the draft is repetitive. It does not mean a model wrote it.

• A short caption

  Twenty words is not enough. The tool asks for 40 words so a single sentence is not treated as a pattern.

Main features

• Average sentence length and a low, moderate, or varied label.
• A vocabulary label based on how many different words appear.
• Four-word phrases that show up three or more times.
• A short list of stock phrases, when they are present.

How it works

Sentence variation compares the spread of sentence lengths with the average. Vocabulary compares unique words with total words. Both measures move around in ordinary editing. A careful human draft can look even. A generated draft can look varied. The page says that in the result.

Tips

• Use a full section, not a headline.
• Treat repeated phrases as an editing note. Cut them if the reader would notice.
• Do not use the labels to accuse someone of using a model.

Limitations

The browser check needs at least 40 words. It reports sentence length, vocabulary spread, and repeated phrases. It does not return a percentage or a verdict that a model wrote the draft. Analyze with AI sends the text to Gemini for the same kind of description.

FAQ

Can this tell if text was written by AI?

No. It cannot do that with certainty. Pattern checks produce false positives and false negatives. The result is a description of the draft, not a verdict.

Why is there no percentage score?

A percentage would look like proof. Analyze writing and Analyze with AI both describe patterns. Neither one claims it can tell who wrote the text.

Is my text sent to a server?

Analyze writing counts patterns in this tab and does not upload the draft. Analyze with AI sends the draft to Google's Gemini API through ToolStarHub for a written description. ToolStarHub does not save that text. On the free tier, Google may use it to improve its products.

Are AI detectors accurate?

No detector can prove who wrote a text. Pattern-based scores can flag human writing and miss edited AI writing, so treat any result as a prompt to review, not as evidence.

What patterns does this tool look at?

It reports sentence length, how varied the vocabulary is, and repeated phrases, so you can see where a draft sounds flat or repetitive.
