Free AI Content Detector — Unlimited Detection Forever

The AI content detection market is full of 'free' tools that aren't really free. Limited scans per month, word count caps, premium features locked behind paywalls, trial periods that auto-convert to paid subscriptions. Reilaa is different: genuinely free AI content detection with unlimited use, forever.

We don't believe in freemium restrictions that frustrate you into paying. Our free AI content detector gives you everything: unlimited scans, any content length, full detection capabilities, and Turnitin estimation included. No features reserved for premium tiers because there are no premium tiers.

This commitment to being truly free stems from our belief that AI content detection is now essential—especially for students. When professors use Turnitin to check every submission, students need access to detection tools. Creating financial barriers to this access is unfair. Hence, completely free AI content detection.

What you see is what you get. Visit Reilaa, paste your content, receive comprehensive AI detection results including Turnitin estimation. No account required, no payment information, no hidden costs. Just free, powerful AI content detection whenever you need it.

Our free AI content detector identifies text generated by all major language models. ChatGPT (both GPT-3.5 and GPT-4), Claude (all versions), Google's Gemini, Meta's Llama, Mistral, and virtually any AI writing assistant. The detection technology recognizes patterns common across AI systems rather than targeting specific models.

AI-generated content exhibits characteristic patterns regardless of which model created it. Perplexity patterns show predictable word choices. Burstiness reveals uniform sentence structures. Semantic coherence demonstrates formulaic idea development. Our free detector analyzes all these dimensions simultaneously.

The detection works across all content types: essays, research papers, blog posts, articles, reports, creative writing, business content, and more. Academic submissions, professional documents, published content—our free AI content detector handles any text that needs verification.

Detection quality rivals premium paid services. Multi-layered analysis examining perplexity, burstiness, semantics, and style provides comprehensive evaluation. You're not getting a watered-down 'free' version—you're getting full professional-grade AI content detection at no cost.

Students face a unique AI content detection challenge. Every paper submitted to Turnitin gets scanned for AI-generated content. High scores trigger integrity investigations with serious consequences—failed assignments, academic probation, even expulsion. Yet students are least able to afford premium detection tools.

Our free AI content detector addresses this inequity directly. Every student—regardless of financial situation—gets access to the same powerful detection capabilities. Check papers before submission, identify potential issues, make revisions, and verify improvements. All free, all unlimited.

The Turnitin estimation feature is especially valuable for students. General AI content detection is useful, but knowing how Turnitin specifically will score your paper is essential. Our free detector provides both: general AI detection plus Turnitin prediction, so you understand exactly how your submission will be evaluated.

Beyond just checking final papers, students can use our free AI content detector throughout the writing process. Test your outline, scan drafts, verify revisions. This iterative approach—impossible with limited paid services—improves both your detection scores and your writing skills.

AI content detection relies on identifying patterns that distinguish human writing from machine-generated text. Despite AI's sophistication, measurable differences exist in how humans versus algorithms construct text. Our free detector analyzes these differences through multiple lenses.

Perplexity analysis measures word choice unpredictability. Human writers naturally produce varied, sometimes unexpected vocabulary selections based on context and personal style. AI systems, trained on statistical patterns, tend toward more predictable choices. High perplexity variation suggests human authorship.

Burstiness examines sentence structure variation. Human writing naturally fluctuates—short punchy statements, then longer complex sentences, then concise points again. AI tends toward more uniform sentence patterns. Our free AI content detector measures these rhythmic differences.

Semantic analysis evaluates idea development and coherence. Human arguments develop organically with occasional tangents and non-linear progression. AI follows more formulaic structures with systematic logical flow. Combined with stylistic analysis, these layers produce comprehensive, accurate detection.

Limited scans force compromises. With only 5-10 checks per month, do you use them on rough drafts or save them for final versions? Our free AI content detector eliminates this dilemma: check unlimited content, unlimited times, without ever worrying about running out.

Unlimited scanning enables iterative improvement. Check your first draft, see what triggers detection, revise those sections, verify the changes helped. Repeat until you're confident. This iterative workflow—the best approach for improving both scores and writing quality—requires unlimited access.

Learning happens through experimentation. Which writing techniques produce more authentic-sounding content? What revision strategies lower AI scores most effectively? With unlimited free scans, you discover these patterns through direct testing rather than expensive trial and error.

Collaborative use benefits from unlimited access too. Study groups can share the tool, checking each other's work without worrying about using up limited scans. This collaborative learning—impossible with restricted services—becomes natural with truly free unlimited AI content detection.

Most free AI content detectors provide generic detection only. Reilaa includes something critically important: Turnitin AI detection score estimation. This feature predicts how Turnitin—the platform your school actually uses—would evaluate your content.

Why does Turnitin estimation matter? Different detection systems can score the same content differently. A paper might pass generic AI detectors but trigger Turnitin's academic-specific algorithms. Knowing your Turnitin score specifically prevents nasty surprises when your paper goes through official institutional scanning.

Turnitin is used by over 15,000 educational institutions worldwide. When professors check submissions, Turnitin's AI score is what they see. Our free AI content detector helps you see that same score before submission, giving you opportunity to address any issues while the paper is still in your hands.

This Turnitin estimation—free and unlimited—transforms how students can prepare submissions. Check drafts, identify problems, make revisions, verify improvements, all while seeing exactly how Turnitin would evaluate each version. No other free AI content detector provides this critical academic-specific insight.
