Let's TryWe believe that no AI content detector can claim 100% accuracy in determining whether a text was generated by AI or written by a human. AI text generators can produce text in various styles, and each new version becomes better at mimicking human writing.
That's why we see AI detection as a general measurement of how artificial a text appears and how much it may be influenced by AI. As a result, we prefer using "Text Artificiality Score" rather than "AI Detection Score", which some might interpret as a definitive claim of detecting AI-generated content.
We calculate the Text Artificiality Score by classifying sentences into six levels of artificiality, measuring their lengths, and computing a weighted average.
Defining a "good" AI detection score is tricky because every AI checker uses its own detection algorithms, evaluating text from different perspectives. Additionally, the accuracy of these tools varies depending on the text itself, which can lead to differences in results.
We measure text artificiality, with scores below 50% indicating mostly human-written content, above 50% suggesting AI influence, and over 80% showing strong AI influence.
However, a high score—even 100%—doesn’t always mean the text was AI-generated. For example, if a person's writing style is similar to AI-generated text or if a human-written text has been grammar-checked by AI, the score may be higher than expected. Likewise, a low artificiality score doesn’t always guarantee human authorship—some AI-generated text can be carefully crafted using user-provided words or styles to appear more natural.
Not necessarily! If you are checking your own writing or have only used AI for grammar corrections, you don’t need to worry—the authorship is still yours. The score is simply an estimate of how much the text resembles AI-generated content, not definitive proof of AI authorship.
If you want to see which sentences contributed to the overall score, we use color coding to highlight them. However, don’t focus too much on a single sentence, as AI detection for individual sentences can be highly inaccurate.
Whether you need a Spanish AI detector or a French AI detector, our tool has you covered. The AI checker supports multiple languages—simply choose the language when you upload your text and get an AI detection score instantly.
