How our AI essay detection tool works

Generic grammar and plagiarism checkers aren't designed to detect AI-generated papers. Ours is. Our AI essay checker evaluates your paper across 30+ signals that help distinguish human writing from machine-generated text, including:

Structural uniformity

Neatly mechanical paragraphs lack the quirks, inconsistencies, and personal voice found in human writing.

Perplexity & predictability

AI-generated essays are often unusually smooth and highly predictable from one word to the next.

Burstiness

Students naturally mix short and long sentences. AI produces more uniform sentence lengths and structures.

Lexical variety

Repetitive vocabulary and unusual word patterns are common indicators of AI-generated text.

Phrasing footprints

Over-polished language, hedge-heavy transitions, and other stylistic patterns commonly favored by LLMs.

Go beyond the score. Every flagged sentence comes with detailed insight into the signals and patterns that influenced the result.

What your results look like

The AI checker splits your text into smaller chunks and highlights the areas with the strongest signs of AI-generated writing. Because each section is analyzed separately, treat flagged parts as review signals rather than final verdicts — especially for short or borderline text.

The evolution of electrical technology has transformed human life from simple experiments with static charge to a vast, interconnected power infrastructure. Early discoveries by scientists like Volta and Faraday laid the groundwork for practical generators, motors, and circuits. The invention of the light bulb and widespread electrification in the 19th and 20th centuries changed industry, transportation, and daily life. Today, advances in semiconductor technology, renewable energy, and smart grids are reshaping how we produce, store, and manage electricity. As we move forward, innovations in batteries, energy-efficient devices, and decentralized generation promise a cleaner and more resilient electrical future.

Accurate and honest about limits

No AI essay detector is 100% accurate, and any tool that claims to be isn't being straight with you. Our checker is tuned to minimize false positives — wrongly flagging human writing — because that's the mistake that hurts students most. If your essay is truly your own, it should read as human here. If a section is flagged and you wrote it yourself, treat it as a prompt to vary your phrasing, not as an accusation.

Frequent Questions

Ahead are answers to commonly asked questions concerning our papers writing help. We are happy to address any additional questions you may have via email, live chat or phone.

Is this AI essay checker free?: Yes. You can run unlimited checks without creating an account or worrying about daily limits. There's also nothing to install.

Do colleges and teachers actually check essays for AI?: Yes. It's becoming increasingly common for schools and universities to use tools such as Turnitin and GPTZero to check whether students have used AI to write their essays. Some institutions also have specific policies regarding AI use. That's why it's a good idea to review your work before submitting it, to help avoid false flags.

Can it give a false positive on my own writing?: Yes. If your writing is flagged, it may be because it appears overly polished, formulaic, or highly predictable — this can happen to anyone. Try varying your sentence structure, using more natural phrasing, and adding specific details, then run another check to see whether the score improves.

How do I make my essay pass as human?: Write authentically. Add specific personal details, vary sentence length, remove overly polished transitions, and allow some natural imperfections to remain. AI-generated text tends to be smooth and uniform, while human writing usually has more personality and variation.

Does it work for college application essays?: Yes. It's particularly useful for personal statements and Common App essays, where sounding authentic and genuinely human matters most.

Which AI models can it detect?: It recognizes writing from all the major large language models, including ChatGPT, GPT-5, Claude, Gemini, and Llama.

How accurate is the AI detection?: This tool analyzes your essay across more than 30 signals to provide a reliable estimate, but no AI detector is perfect. We've worked to minimize false positives on clearly human-written content. Use the results as a guide rather than a final verdict.

Will my essay be stored or shared?: No. Your essay is processed securely and is not stored or shared, so you can check your work with confidence — even if it's confidential or graded.

What's the difference between an AI checker and a plagiarism checker?: A plagiarism checker looks for content copied from existing sources. An AI checker estimates whether text was generated by AI, even if the content is completely original. They serve different purposes, which is why many writers use both.

Do I need to download anything?: No. The tool works directly in your browser on any device. Simply paste your essay and get instant results.
