AI Detector｜No Made-Up Scores
Paste your essay or upload the manuscript — every AI-like passage quoted and explained. No percentages, just evidence.
Free AI detector: paste text or upload a draft to review AI writing patterns passage by passage, each tied to a quote — no fake scores. Try it free today.
Features
- Every claim quotes you——Each observation cites your exact sentence: which passage is vague, which transition is templated. No guessing.
- No invented percentages——No classifier, no pretending. The verdict has three levels: widespread patterns, isolated boilerplate, or nothing notable.
- Rewrite tips with examples——Every flagged passage gets a fix: which cliché to cut, which detail to add — follow it and the AI feel fades.
- Downloadable report——Analysis, stat tables, and the limitations statement export as .docx/.pdf — easy to file or forward.
How it works
- Paste or upload the text Paste the full text — longer is better — or upload the PDF/DOCX. Set the genre baseline first (essay, blog, or application letter) and pick self-check or review mode. Under ~100 words you get writing tips only.
- Agent reads passage by passage Quoted passages flag repeated structures, templated transitions, and generic wording — each with its alternative explanation.
- Read evidence, then revise Quoted passages plus alternative explanations at a glance: self-checkers take the rewrite examples, reviewers take the talking points — and download the report.
FAQ
- Is the AI detector free? Do I need an account?
- Free, no sign-up — open the page and paste your text. For long pieces, check them section by section; PDF, DOCX, TXT, and MD manuscripts can be uploaded as attachments.
- How is this different from GPTZero or Turnitin?
- Different jobs. Turnitin lives inside school plagiarism systems and individuals cannot buy it; GPTZero is a percentage classifier that is free and easy but false-positive prone. We run no classifier and invent no scores — only passage-level writing-pattern analysis with quoted evidence and alternative explanations, built for self-revision and review conversations. For high-stakes calls, cross-check with two or three tools.
- How accurate is this AI detector? Any false positives?
- Every detector misfires, and flagging human writing is extremely common. To sanity-check a result: use texts well over 300 words, cross-check with two or three tools, and run your own confirmed human writing through as a control. Template-style official prose, exam set phrases, translated writing, heavily bulleted structure, and formula-heavy science explanations are misflagged most.
- Does translated or ESL writing get flagged?
- Yes — that is the false-positive hotspot. Translationese and classroom set phrases learned by ESL writers read almost identically to AI-like prose. Our report puts “this could also be translation or ESL” next to every observation, and review mode states it plainly: formal register alone is not evidence.
- Can it catch paraphrased or humanized text?
- Poorly for heavily polished adversarial samples, and we say so honestly: only residual traces remain, so pair the report with draft history and a conversation with the author. The legitimate way to lower the AI feel is outlining and drafting yourself first, adding lived details and real numbers, cutting templated phrases, and reading it aloud. We do not teach detector evasion.
- Can it check whether an image is AI-generated?
- No — this tool reads text only. Image detection is a different technique and a separate need, looking at fingers, lighting, noise, and metadata. For pictures, use a dedicated AI image detector; this page solves manuscript text.
- How reliable is it on Chinese text?
- Not reliable — no Chinese AI writing detector is, since training data is overwhelmingly English. For Chinese manuscripts we lower expectations: no AI-or-human verdict, only notes on formulaic, bureaucratic, or translated-sounding expression with concrete revision directions.
- Does it work on short texts?
- No overall verdict under ~100 words — no detector can judge short text. For short pieces like cover letters, you get sentence-level writing tips instead: how to swap each cliché for something you actually did, plus why no verdict is given.
- Is one-second AI text spotting real?
- Mostly a gimmick. Detectors compute probabilities, not DNA: human-written official prose and translated writing routinely test as AI, while AI text survives with light paraphrasing or a few typos. Fine as an initial screen, never as evidence — and never as the sole basis for accusing a student.
