AI Text Detector

Select any text and the ai text detector scores how likely chatgpt wrote it: essays, articles, cover letters. Local, no account.

🔍 AI Text Detector tells you in a second whether a paragraph came from a language model or from a person. Select a passage on any page, open the popup, and you get a reading plus the sentences that look machine written. Everything runs inside your browser. The ai text detector never uploads your document, never asks for an account and never keeps what you check. Teachers, editors and recruiters read confidential drafts daily, and those drafts should stay put. ⚙️ How the analysis works The extension measures what a language model does differently from a person: ➤ perplexity, or how predictable every next word is ➤ burstiness, or how much sentence length and rhythm vary ➤ repeated connectors, hedges and template openings ➤ vocabulary spread, uncommon words, and how much a passage restates itself Human writing is uneven: a long sentence follows a short one, ideas jump sideways, odd words slip in. Generated prose is flatter, and this ai detector text analysis catches the flatness without sending a byte out of Chrome. 📊 What the report shows - one overall reading of low, medium or high, with a verdict in plain words - a sentence heat map showing which parts look generated - each of the four signals with its own reading - word and sentence counts you can copy into a report 1️⃣ Select a passage on a page, or paste it into the popup 2️⃣ Press Check and wait about a second 3️⃣ Read the verdict, then open the sentence view for detail 🎓 Who reaches for an ai generated text detector every day 1. Teachers and graders reading student essays who want a signal before a conversation 2. Editors accepting articles from a rotating pool of writers 3. Recruiters screening cover letters and take-home assignments 4. Writers checking a draft before the client sees it 5. Students making sure a rewrite still sounds like them 📌 Situations it was built for 📍 An essay checker moment: a paper lands an hour before the deadline, suspiciously smooth 📍 A paper checker moment: one chapter has a different voice from the rest 📍 A writing checker moment: a guest post has flawless grammar and zero personality 📍 An originality checker moment: the same phrasing shows up in three submissions 🔒 Privacy is the whole point Online services want confidential material pasted into a web form, then ask you to trust their retention policy. This ai detector for text stays local: no upload, no telemetry, no login. The permission list is short, since the extension reads only your selection. 🎯 Honest about what a reading means No text ai detector can prove authorship, and this one will not pretend otherwise. The reading is a probability drawn from writing patterns: treat a high one as a reason to look closer, never as a verdict. It comes back as low, medium or high rather than a number out of a hundred: four heuristics cannot honestly separate a 61 from a 67. Short fragments are the weak spot, so give the ai detector in text a few hundred words. Used that way, ai text detectors save you from reading on autopilot. 🌍 Language and format support Scoring covers English plus the major European languages, while markdown, quoted replies and code blocks count as noise. Long files are analysed in chunks, and since the model ships inside the extension it works as an ai text detector online or offline. The ai written text detector strips formatting first. 📚 Where it fits next to other tools A plagiarism detector asks whether a passage appeared before. A readability checker measures sentence difficulty, an essay grader estimates a mark. A text scanner pulls words from an image and a text analysis tool counts what it sees. This ai generator text detector answers the authorship question instead. ❓ Frequently asked questions Does the ai text generator detector need an internet connection? No. Every check runs locally, which is why an online ai text detector cannot match it on privacy. How much writing does it need? Around 150 words is the practical floor. Below that, any of the ai text detector tools out there guesses more than it measures. Does it recognise output from a specific model? It reports patterns common to current language models rather than naming a product, so a chatgpt detector style answer is a probability, not a brand label. Is my writing stored or sent anywhere? Never. The history lives in local storage and one click wipes it. Can I check a pdf in the browser? Open it, select the passage and right-click it. Chrome does not hand a pdf selection to the toolbar button. Is this a chatgpt checker for teachers only? No. Editors and recruiters use it as much, so a thesis checker case sits next to a hiring one, and academic integrity is one scenario of many.
