A free AI checker for teachers: paste a student essay or Google Classroom submission to estimate whether it was written with ChatGPT or other AI, then review it before grading.
Detect AI-generated text in seconds. No account needed, no setup required.
Purpose-built for academic integrity — not just a generic AI checker.
Uphold academic honesty by detecting AI-generated submissions before they reach your gradebook. Identify patterns consistent with ChatGPT, GPT-4, Gemini, and other large language models.
Get an AI probability score in seconds — no sign-up required. Paste text and click Detect to see results immediately, saving you time during the grading workflow.
Designed with teachers in mind. Works seamlessly alongside EduSageAI's grading tools so you can evaluate both the quality and authenticity of student work in one platform.
Our detector is trained to recognize writing patterns from all major AI tools — ChatGPT, GPT-4, GPT-4o, Claude, Gemini, Llama, and more — not just one model.
From STEM reports to humanities essays, the AI detector works across all subject areas and writing styles, making it a reliable tool regardless of what your students are submitting.
Results are shown as a probability score, not a guilty verdict. This encourages educators to use AI detection as a starting point for conversation, not as a sole basis for punishment.
This page is built for quick, practical use: paste text, check AI generated text, and decide whether a submission needs a closer human review. If you need a fast AI generated writing detector for essays, reports, or a short paper AI detector workflow, the tool above is the right entry point.
Teachers can also use this page as a Google Classroom AI checker by pasting student writing from Classroom before final grading. It supports common search needs like AI checker for teachers free, ChatGPT checker for teachers, AI checker ChatGPT, and free AI checker for students, while keeping the result framed as a review signal instead of an accusation.
If your intent is educational research rather than instant analysis, read our guide on how to detect AI-generated text and check if something was written by AI. That article covers how AI detectors work, when false positives happen, and how teachers should interpret GPT detection results.
Teachers comparing AI detection tools usually care about three practical things: how much text the tool needs before the result means anything, whether it can handle a full class set or only one submission at a time, and whether student writing is stored after the check. Detectors are weakest on short responses, on heavily edited AI text, and on writing from multilingual students whose sentence patterns can look statistically unusual. A tool that reports a single confident verdict is hiding those limits rather than solving them.
What a score does show is that a submission is worth a second look. What it does not show is who wrote the text. A high percentage is a statistical estimate about writing patterns, not evidence of authorship, and it cannot distinguish between a student who used AI to draft an essay and a student who used it to tidy up sentences they wrote themselves. Treating the number as proof is where AI detection goes wrong for teachers — and where it becomes unfair to students.
The follow-up conversation is the part that actually resolves things. Ask the student to walk you through how the piece came together, look at the revision history in Google Docs or Classroom, and compare the submission with earlier work you have already seen from them. Most cases sort themselves out in that conversation. Pair the check with rubric-based grading so the grade still rests on the work in front of you, and set the expectation with your class before the assignment rather than after a flag.
EduSageAI is an AI grading platform that includes both AI detection and plagiarism checking. The AI detector on this page is free and needs no account (up to 999 characters), and the EduSageAI AI Plagiarism Checker is included on the Basic, Premium and Enterprise plans alongside essay, exam and code grading.
The AI Plagiarism Checker is part of the Basic plan (10 USD per user per month, 200 evaluations), the Premium plan (25 USD per user per month, 1,000 evaluations, Advanced AI Plagiarism Checker) and the Enterprise plan (custom pricing, Advanced AI Plagiarism Checker). The Free plan (0 USD, 50 evaluations) does not include the plagiarism checker. Full plan details are on the EduSageAI pricing page.
The same EduSageAI account grades essays with the AI essay grader, open-ended exam answers with the AI test grader, and programming assignments with code grading, which compares code structure and logic across submissions to flag similarities. Grading on every plan draws from one shared pool of evaluation credits.
Turnitin, Copyleaks and Originality.ai are detection-first tools built mainly to check originality. EduSageAI takes a different approach: AI detection and plagiarism checking sit inside a rubric-based grading workflow, so the integrity check and the grade happen in one place.
Screening a submission is the first step, not the last one. Once you have decided a paper is worth grading normally, these are the EduSageAI tools teachers move to next.
EduSageAI's free AI checker estimates how likely it is that an essay or assignment was written with AI tools like ChatGPT. Results are review signals to discuss with the student — not standalone proof — and work best alongside rubric-based grading. The practical teacher workflow is to screen the submission, check the draft history, and talk to the student before any grading decision is made.
Everything you need to know about AI text detection and how to use it responsibly.
An AI text detector (also called an AI content detector or AI writing detector) is a tool that analyzes text to determine the likelihood that it was generated by an AI model such as ChatGPT, GPT-4, Gemini, or Claude. It works by identifying patterns in vocabulary, sentence structure, and writing style that are statistically more common in AI-generated content than in human writing.
Yes. EduSageAI offers a free teacher AI detector for quick classroom checks, helping educators review essays, short responses, and other written work before final grading decisions.
Yes. Teachers can paste writing from Google Classroom submissions into EduSageAI's AI checker for a quick screening result before making any grading or academic-integrity decision.
Yes. Students can use the free AI checker to understand whether their writing may be flagged, but the result should be treated as guidance rather than proof of authorship.
Yes. EduSageAI's AI detector is trained to recognize writing patterns from ChatGPT (including GPT-3.5 and GPT-4), as well as other major large language models like Google Gemini, Anthropic Claude, Meta Llama, and more. No detector is 100% accurate, but our model is regularly updated as AI writing styles evolve.
Yes, the AI text detector on this page is completely free to use without creating an account. Simply paste your text (up to 999 characters) and click Detect AI Text to get your result instantly. For higher volume usage and deeper integration with grading workflows, explore EduSageAI's full platform.
Accuracy varies depending on text length, writing style, and how heavily edited the AI-generated text is. Short texts (under 100 words) are harder to classify reliably. Results are presented as a probability score — not a definitive verdict — and should be used alongside educator judgment rather than as standalone proof of academic dishonesty.
Lightly edited AI text can sometimes reduce detection confidence, though our model accounts for common paraphrasing and editing patterns. Heavily rewritten AI text may be difficult for any detector to flag reliably. This is why AI detection results should be one signal among many — not the sole basis for an academic integrity decision.
EduSageAI takes privacy seriously. Text submitted through the public demo is used solely to return a detection result and is not stored or used for training purposes. For full privacy policy details, visit our privacy policy page.
The AI score represents the estimated probability that the submitted text was generated by an AI model. A score of 0–39% suggests likely human writing, 40–74% suggests possible AI involvement, and 75–100% suggests the text is likely AI-generated. Always interpret these scores in context — writing style, subject matter, and student history all matter.
There is no single standard. Teachers in institutions with a Turnitin license usually get AI detection through that; teachers without one use a free or teacher-priced detector such as EduSageAI's AI checker for quick screening. What matters more than the brand is how the result is used — as a signal that prompts a closer look at the draft history and a conversation with the student, not as a verdict.
Yes. EduSageAI's AI detector on this page is free and needs no account, which makes it practical for spot checks on a single submission. Free tools generally cap text length — 999 characters here — so for whole-class screening across a term, a paid or institutional tool with batch processing is usually the better fit.
Start by treating the score as a question, not an accusation. Re-run a longer sample if the text was short, check the draft and revision history in Google Docs or Classroom, and compare the writing against work you have already seen from that student. Then talk to the student about their process. A detection score alone should never be the sole basis for an academic integrity decision.
Plagiarism detection checks whether text was copied from an existing source (a website, paper, or another student's submission). AI detection checks whether text was generated by a language model — which would not appear in any plagiarism database since the AI generates original text. EduSageAI offers both capabilities as part of its broader academic integrity toolkit.
EduSageAI is an AI grading platform that includes an AI Plagiarism Checker alongside essay, exam and code grading, plus the free AI detector on this page. Turnitin, Copyleaks and Originality.ai are detection-first tools focused on originality checking, while EduSageAI puts detection and plagiarism checking inside a rubric-based grading workflow. For coding assignments, EduSageAI compares code structure and logic across submissions to flag similarities.
The AI Plagiarism Checker is included on the Basic plan ($10 per user per month, 200 evaluations), and the Advanced AI Plagiarism Checker is included on the Premium plan ($25 per user per month, 1,000 evaluations) and the Enterprise plan (custom pricing). The Free plan ($0, 50 evaluations) does not include the plagiarism checker. The free AI detector on this page needs no account on any plan.
