Free AI Detector
Unlimited AI Content Detection

Reilaa is the most advanced free AI detector designed specifically for students, educators, and academic professionals. In an era where AI writing tools like ChatGPT, GPT-4, and Claude are widely accessible, protecting yourself from false AI accusations has become critical. Our powerful AI detection tool provides unlimited, professional-grade content analysis completely free—no hidden costs, no usage limits, no sign-up required.

Unlike expensive AI detection services that charge $10-30 monthly or impose strict scan limitations, Reilaa offers truly unlimited AI content detection. Check your essays, research papers, assignments, and academic writing as many times as needed throughout your writing process. Our advanced multi-layer detection technology analyzes your text for AI-generated patterns and provides accurate scores including Turnitin estimation—the most widely used academic integrity platform worldwide.

Whether you're a high school student, college undergraduate, graduate researcher, or educator, Reilaa empowers you to verify content authenticity before submission. Our free AI detector helps prevent academic integrity violations, protects against false positives, and gives you confidence in your original work. With instant results, privacy-first processing, and zero financial barriers, Reilaa makes professional AI detection accessible to everyone.

Most AI detection tools operate on restrictive freemium models designed to frustrate you into upgrading. They limit scans to 5-10 per month, cap word counts at 250-500 words, or require credit card information for "free trials." These artificial limitations make it nearly impossible for students to properly check their work throughout the writing process. Reilaa eliminates all these barriers.

Our AI content detector provides genuinely unlimited scans with no word count restrictions. Check a 500-word essay or a 15,000-word dissertation—as many times as you revise and improve your work. This unlimited access transforms AI detection from a one-time gate-keeping tool into a valuable learning resource that helps you develop better writing habits and understand how your style affects detection scores.

The Turnitin score estimation feature is particularly valuable for students. With over 15,000 institutions worldwide using Turnitin for plagiarism and AI detection, knowing your likely Turnitin score before official submission can prevent serious academic consequences. Our advanced algorithms analyze your text and predict how Turnitin's AI detector would score your content, giving you opportunity to revise flagged sections before they become problems.

Our AI detection technology uses sophisticated machine learning algorithms trained on millions of examples of both human-written and AI-generated text. The system analyzes multiple linguistic markers, statistical patterns, and writing characteristics that distinguish artificial intelligence output from authentic human composition.

When you submit text to Reilaa's free AI detector, our algorithms examine perplexity (text predictability), burstiness (sentence variation), semantic coherence (idea flow), and dozens of other subtle indicators. AI-generated content tends to be more uniform, predictable, and formulaic, while human writing exhibits natural variation, personal voice, and occasional imperfections. Our multi-layered analysis identifies these patterns with high accuracy.

The detection process happens in seconds. Simply paste your text, click analyze, and receive comprehensive results including an overall AI detection score and Turnitin estimation. Unlike tools that only provide a yes/no answer, Reilaa gives you nuanced feedback that helps you understand which aspects of your writing might trigger AI detection systems. This detailed insight enables targeted revisions rather than wholesale rewrites.

When you use our AI detector, you receive percentage scores indicating the likelihood your text was AI-generated. Scores from 0-20% generally indicate human-written content with minimal AI characteristics—this is the safe zone for academic submissions. Scores from 20-50% suggest possible AI elements or heavily edited AI content that may raise questions. Scores above 50% indicate significant AI-generated content that will likely be flagged by academic integrity systems.

It's important to understand that no AI detection tool achieves perfect accuracy. False positives occur when exceptionally clear, well-structured human writing resembles AI's organized output. False negatives happen when heavily edited AI content incorporates enough personal elements to obscure its origins. This is why having unlimited free scans is valuable—you can check multiple drafts, experiment with revisions, and verify improvements without worrying about running out of checks.

The Turnitin estimation score specifically predicts how Turnitin's proprietary AI detection system would evaluate your content. Since Turnitin is the most common tool used by schools and universities, this estimation is particularly relevant for students. If your Turnitin estimate is high while other scores are moderate, you can focus on the specific elements Turnitin weighs heavily, such as extremely formal language or perfectly structured paragraphs.

Students face unprecedented challenges navigating AI policies in education. Many schools have implemented strict rules against AI usage, yet AI detection systems regularly produce false positives that accuse innocent students of cheating. Being falsely flagged for AI usage can result in failing grades, academic probation, or even expulsion. Using a free AI detector before submission is essential self-protection.

Reilaa gives students the same detection technology their professors use, leveling the playing field. By checking your essays and papers before submission, you can identify sections that might trigger AI detection—even if you wrote them entirely yourself. Clear, concise writing with formal academic language sometimes resembles AI output. Our AI detection tool helps you recognize these patterns and add more personal voice, specific examples, or stylistic variation to demonstrate authentic authorship.

The completely free, unlimited nature of Reilaa makes it perfect for student budgets and workflows. Check your outline, first draft, revised version, and final submission—as many iterations as your writing process requires. Learn from the feedback, improve your writing style, and develop habits that produce authentically human content. This isn't just about passing AI detection; it's about becoming a better, more distinctive writer.

When using AI detection services, students rightfully worry about their original academic work being stored, shared, or added to plagiarism databases. Some tools explicitly state they use submitted content to train their models or build comparison databases. Reilaa takes a fundamentally different approach: we never store your text beyond the immediate analysis period.

When you submit text to our free AI detector, it's processed in real-time and immediately discarded after results are delivered. Your essays, research papers, and assignments never enter permanent storage, databases, or training datasets. We don't require account creation specifically to avoid collecting personal information. No email addresses, no login credentials, no tracking of individual usage patterns—just instant, anonymous AI detection.

This privacy-first approach means you can confidently check proprietary research, sensitive academic work, or unpublished writing without fear of it being compromised. Your intellectual property remains yours alone. For students working on original theses, dissertations, or research that will eventually be published, this guarantee of confidentiality is essential.
