We tested it in November 2026 on 466 texts: 221 human-written texts from before ChatGPT existed (137 real student essays, 32 of them by English-language learners, plus 84 of our own essays and guides) and 245 texts written or edited with GPT-4.1, GPT-4o-mini and Claude.
| What we tested | Result |
|---|---|
| Definite verdicts that were correct | 97% |
| AI texts labelled AI or inconclusive | 98% |
| AI text reworded to sound human, labelled AI or inconclusive | 97% |
| Genuine human texts wrongly labelled “Likely AI-written” | 3% (7 of 221) |
| Essays by English-language learners wrongly labelled AI | 1 of 32 |
| Texts given an “Inconclusive” result | 14% |
No AI detector is perfect. If you wrote your essay yourself and still get “Likely AI-written”, keep your notes and drafts: they are the best evidence that the work is yours. We use an “Inconclusive” band so borderline writing is never presented as proof, and we re-run this test as new AI models appear. English gives the most reliable results. Student essays: PERSUADE 2.0 corpus (CC BY 4.0).
We tested this detector on 466 texts, including 137 real student essays and writing from GPT and Claude models. 97% of its definite verdicts were correct, and when a result is borderline it says so instead of guessing.
This software has a clean, compelling, and intuitive website design. It doesn’t require any technical knowledge to operate. Just paste or upload your text and click “Detect AI”.
You get one of three verdicts: likely human-written, inconclusive or likely AI-written. When the evidence is borderline, the detector says so instead of guessing.
We don’t store your text. It is checked by our AI-detection partner, and we keep only the scores, so it is safe for sensitive academic or professional writing.
Teachers can use this AI detector to check student work, content editors to review submitted articles, students to ensure originality, and freelancers to verify deliverables.
This AI detector software is perfect for academic use. Students and universities can use it to check assignments, essays, or papers to avoid academic misconduct.
The first step is pasting the text. Copy your preferred text and paste it into the input box of ResearchProspect’s AI detector.
Select a specific word count, as this tool optimises analysis based on input length. This will significantly improve your results.
Press the “Detect AI” button. The tool analyses your text and shows the result in a few seconds.
You’ll see a verdict, the share of your text in each category and the sentences that read as AI-written. You can email the result to yourself or download it as a PDF.
An AI detection tool is designed to analyse all forms of written text and determine whether it is generated by artificial intelligence (AI) tools, such as ChatGPT, GPT-3, or GPT-4, or written by a human.
The AI detectors use cutting-edge machine learning algorithms trained on large AI-generated and human-written text datasets. They analyse written text and look for subtle patterns in sentence structure, word usage, predictability, and complexity to detect the likelihood of AI usage.
When a specific piece of text is pasted into an AI content detector, it analyses the patterns, structure, and predictability to determine whether the text is human-written or AI-generated using tools like ChatGPT, GPT-3, or GPT-4. Here’s a detailed explanation of how ResearchProspect’s free AI detector works:
AI-generated text tends to have specific patterns, such as overly consistent sentence structures, formal tone, or predictable phrasing. AI detectors are explicitly trained to spot these patterns by comparing them with large datasets of AI-generated and human-written text.
ResearchProspect’s AI detector uses a dedicated AI-detection model, trained on large collections of human and AI writing, to score each sentence and the text as a whole. It looks at signals such as word choice, repetition, sentence length, structure, vocabulary variety, predictability, and randomness of phrases.
The model’s score is turned into one of three verdicts using thresholds we set on our own test of 466 human and AI texts, to keep wrong AI verdicts on human writing as rare as possible.
We don’t store your pasted text. It is sent securely to our AI-detection partner for analysis, and we keep only the scores, never the text itself.
With the increasing surge of AI writing tools, AI detectors have also been introduced. As much as AI is acknowledged for its efficiency, quality, and promptness, it raises multiple concerns, especially in the academic landscape where critical thinking, problem-solving, and creativity are commended. So, this is how AI detectors help students, academics, and professionals ensure that written text is original, unique, and well-researched. Here are the key benefits of our AI detector:
Our AI text detector in the UK helps students and educators verify that submitted essays, assignments, and papers are original and are not AI-generated, maintaining academic integrity, credibility, and authenticity.
ResearchProspect's AI detector is also helpful for avoiding plagiarism. No matter how many times you edit or rewrite your text, the detector can still flag it as AI-generated, allowing you to revise before submission.
AI writing tools are only discouraged if used bluntly. However, they're widely supported if used as assistance. AI detectors also encourage responsible use of AI by allowing users to check the extent of AI involvement in writing.
There are manual methods of knowing whether a piece of text is AI-generated, but they are time-consuming. However, our AI detector gives you a clear verdict in seconds, allowing you to meet tight deadlines.
Another prime benefit of our AI detector is that it helps build trust. It exponentially allows writers, freelancers, and agencies to confirm that submitted work is human-authored, enhancing credibility with clients and editors.
Experience the accuracy and reliability of ResearchProspect's AI detector today.
Lecturers need an AI detector to verify whether students have written their essays, dissertations, and reports by themselves or generated using AI tools like ChatGPT.
Students who have used AI as a writing assistant rely on our AI detector to ensure that their scholarly work meets originality standards before submission.
Content editors, when they send articles, blog posts, or reports for publishing, use a reliable AI detector to verify that they are human-written, safeguarding their credibility.
Journalists trust our advanced AI detector so that they can identify and debunk fake news by analysing the textual data, sources, and the context of information.
Freelance writers, marketing firms, and SEO agencies use AI detectors to ensure that their written work is original and unique and doesn't contain any evidence of AI usage.
College staff also uses our remarkable AI detector to detect whether any of their pupils use AI writing tools, as colleges are places for developing proper learning habits.
Every educational institution requires students to write their essays, assignments, research papers, reports, and dissertations by themselves, employing their knowledge, expertise, and skills. The objective is to assess students’ understanding of a specific topic or subject. However, when AI writing tools are used, this process is significantly compromised. To ensure effective academic credibility and integrity, AI detectors have come onto the scene.
Our cutting-edge AI detector in the UK thoroughly analyses pasted text and identifies different patterns to check whether it is AI-generated or human-written. So, what are you waiting for? Trust this exceptional tool and ensure the authenticity of your academic papers.
AI detectors help save time and effort and eliminate the need to read every line. Furthermore, they are fast and efficient in providing final results.
AI detectors encourage users to balance AI assistance with human creativity and critical thinking, supporting ethical practices and academic integrity.
AI detectors help to develop professional credibility, as editors, agencies, and publishers use them to verify whether submitted work meets human-quality standards.
Most users use AI writing tools relentlessly without realising the risks, so AI detectors flag overuse, limiting AI use and avoiding overly relying on them.
An AI detector quickly detects whether a specific text was generated by tools like ChatGPT, GPT-3, or GPT-4 or human-written, ensuring transparency and originality.
Schools, colleges, and universities require students to write their homework themselves. AI detectors help them verify if students' work is genuinely authored and not AI-written.
Our AI detector is not only exemplary in checking the originality, uniqueness, and creativity of academic papers but also highly helpful in improving academic writing skills.
When this delivers results, it demonstrates where AI traces are present by highlighting sentences in different colours and showing the share of text in each category. This significantly allows users to see where the text quality is not up to the mark, enabling them to make modifications and enhance overall textual flow, clarity, and readability.
ResearchProspect’s AI detector highlights the sentences that read as AI-written, so you can see which parts need attention. This helps users understand where to make charges, leading to a smooth edit, rewrite, or rephrase of that portion instantly. Manually editing or rewriting text can be a time-consuming and challenging task. So, in this scenario, ResearchProspect’s AI Humanizer can come in handy. Use it to make your text sound more natural and human-like if you have used AI assistance.
