A quick second opinion on a short text, without creating an account.

Results↑ Contents
The headline verdict for each text, with default settings. Green means the verdict matched what the text really is.
“100% Confidence” is how sure the tool says it is of its verdict, not a share of AI text. The line under it read “AI use appears to exceed 15%” for A and D, and “AI use appears to be 15% or less” for F.
Against other detectors↑ Contents
The same three texts went through three free detectors in our detector comparison on Oct 8, 2026. Text D is where they split.
| Text | Originality.ai | ZeroGPT | Sapling | Copyleaks |
|---|---|---|---|---|
| A · AI | Likely AI | 100% AI | 99.3% AI | 100% AI |
| D · AI, rewritten | Likely AI | 27.6% AI · “Most likely human” | 89.7% AI | 100% AI |
| F · Human | Likely Original | 0% AI | 0.1% AI | 0% AI |
Originality.ai was scanned a day later than the others. One scan per text per tool.
Findings & screenshots↑ Contents
- Text D, Undetectable AI’s rewrite, was “Likely AI – 100% Confidence” with every sentence highlighted. ZeroGPT had called the same 122 words “Most likely human” (27.6% AI).
- The 1889 passage got “Likely Original – 100% Confidence”, every sentence highlighted green. One old, famous human text is a thin control, so read this as one data point.
- The free tool gives a verdict and a confidence, not an AI percentage, so its results don’t line up number for number with ZeroGPT or Sapling.
- The counter went 3 / 3 → 2 / 3 → 1 / 3 → “No free scans left today”. With three texts, there was no room for a second run of any of them.

Artificial intelligence has fundamentally transformed the way students approach their academic work. In today's rapidly evolving digital landscape, AI-powered tools offer unprecedented opportunities to enhance learning outcomes and streamline research processes. Furthermore, these technologies enable learners to access personalized feedback, identify knowledge gaps, and develop critical thinking skills more efficiently than ever before. However, it is important to note that the integration of AI in education also presents significant challenges, including concerns about academic integrity and over-reliance on automated assistance. Ultimately, striking the right balance between leveraging AI capabilities and fostering independent thought will be crucial for educators and students alike as they navigate this new era of learning.
Artificial intelligence is changing how students do their schoolwork. With all the new digital tools available, students can learn more easily and get help with their research. These tools can even give students personalized feedback, help them find areas where they need to improve, and make it easier for them to think critically. But we also need to be careful - using AI in education can be tricky. Some people worry that students might cheat or rely too much on computers to do their work. So, teachers and students need to find a way to use AI that helps them learn without doing all the work for them. This will be important as we move forward in this new way of learning.
We were all feeling seedy, and we were getting quite nervous about it. Harris said he felt such extraordinary fits of giddiness come over him at times, that he hardly knew what he was doing; and then George said that he had fits of giddiness too, and hardly knew what he was doing. With me, it was my liver that was out of order. I knew it was my liver that was out of order, because I had just been reading a patent liver-pill circular, in which were detailed the various symptoms by which a man could tell when his liver was out of order. I had them all. It is a most extraordinary thing, but I never read a patent medicine advertisement without being impelled to the conclusion that I am suffering from the particular disease therein dealt with in its most virulent form.
Text D comes from our Undetectable AI review. Text F is public domain (Project Gutenberg #308). Texts B, C and E from the comparison weren’t scanned: three free scans a day, and text C (91 words) is under the 100-word minimum.
