The most accurate AI detector for texts

An AI detector or AI checker is a tool that estimates whether a piece of text was written by a language model rather than a human. Modern AI detectors and AI checkers like It's AI analyse patterns in wording, structure and probability that are typical for machine-generated output. Under the hood, the system is a set of machine-learning models trained on large datasets of human and AI-generated texts. When you paste your content into the AI checker, the detector scores each part and then produces an overall result. It's AI was benchmarked on datasets such as MGTD, GRiD and HC3, which helps keep AI detection accurate and predictable in real use.

Using an AI checker like It's AI, you can not only detect AI-generated content but also see exactly where it appears in essays and papers. Paste the text into the AI checker and run a scan with deep mode enabled: • The AI checker highlights sentences that look AI-generated; • a word heatmap shows which parts of the essay influence the AI score most; • you can compare AI-likely and human-likely sections when deciding how to grade or revise. This way you rely on a specialised AI text checker and detector instead of guessing based on style alone.

You can test an AI checker online for free by starting with the built-in AI detector and checker on this page. Short texts can be scanned at no cost with our free AI checker, giving you an initial view of potential AI-generated content. For larger projects and regular work, upgrading unlocks deeper reports in our AI checker engine, history and certificates — useful when you need documented proof of originality.

AI detection is a challenging task that many solutions struggle with. However, modern AI detectors and AI checkers like It's AI are highly focused on this problem and can detect AI-generated content with the best accuracy among all solutions. It's AI was evaluated on several public benchmarks and shows high accuracy with low false-positive rates, as you can see in the comparison tables on this page. No tool is perfect, but a well-trained AI detector or AI checker used correctly answers the question "do AI detectors work?" with a practical yes. The key is to treat AI detection results as evidence to consider alongside context, not as the only proof.

Teachers, schools and colleges typically use an AI detector or AI checker to support — not replace — their judgement. Common workflows include: • checking essays before grading with an AI content checker; • grading based on AI presence and overall quality of the work • if the assignment has too high a percentage of AI, then have a conversation with the student about ethical AI usage and ban/ask to rewrite the work Institutions choose different tools; some use It's AI checker, others rely on alternative services. The important part is to combine AI detection with clear policies so students know what is allowed and how results will be interpreted.

Safety depends on the provider. Before trusting any AI detector or AI checker, check how it stores and processes your data: • are texts encrypted in transit and at rest; • are they reused for training; • who can see scan history. It's AI checker is designed so that content is analysed securely and is not shared with third parties after checks are completed. This lets you use the AI detector for sensitive documents while keeping AI analysis under your control.

The "best" solution depends on who you are and what you need. Students might focus on usability and a free AI detector or AI checker, teachers on transparent reports, and businesses on API access and security. However, if we look at accuracy, It's AI is the best AI checker alternative according to a number of benchmarks, including MGTD — the biggest and most robust one. It's AI aims to cover all three scenarios: an accessible web AI checker, and a full platform with batch scanning and integrations for organisations. Benchmarks like MGTD help show where it stands among other AI detection tool and AI checker options.

To get accurate results from an AI detector or AI checker without false positives, focus on three things: 1. A strong model. It's AI checker was evaluated on datasets like MGTD, GRiD and HC3, which provides evidence that its scores are meaningful. 2. Proper use. Scan full texts with the AI checker, not just isolated sentences, and avoid interpreting borderline scores as absolute proof. 3. Context. Compare results with what you know about the writer and the assignment. It's AI combines these principles to offer one of the best AI detector and AI checker experiences: strong benchmark results, careful training to limit false positives and clear explanations that help you make informed decisions.
