Paste a paragraph, an essay, or upload a PDF. We compare it against public sources and tell you which sentences look too close — with links you can click and read for yourself.
The basics that actually work today, plus a few things we're still building.
Splits your text into sentences and compares each one against public Wikipedia pages. You get a percentage and the actual source links — not just a score.
A simple flag for passages that look like they were written by ChatGPT or similar. In testing — coming on the Premium plan.
When we find a match, we generate a quick APA / MLA reference for the source so you can add it instead of paraphrasing.
Sign in and your scans are saved to your dashboard. Export any scan as JSON or print it to PDF.
From the pilot run with classmates and a couple of lecturers at ICT University.
"I ran my project report through it and it caught two paragraphs I'd paraphrased from Wikipedia without realising. Saved me from a re-do."
"The fact that it shows the exact source link is what sold me. I can talk to students about the match instead of just arguing about a number."
"Honestly was sceptical at first because it's free, but the matches are decent. Wish it also checked academic papers, not just Wikipedia."
The free plan covers most student use. The paid plans are for people scanning a lot.
What we use ourselves day to day.
If you're writing a lot — a thesis, blog posts, regular assignments.
For research groups and lecturers who scan whole class sets.
A few things people usually ask before signing up.
Yes. 1,000 words per scan, 5 scans per month, no card needed. We made it free because that's what we needed as students.
We split your text into sentences, take 5-word chunks (n-grams), and look them up against Wikipedia pages we pull from the public API. If enough chunks match, the sentence gets flagged with a link to the source.
Right now, yes — that was the most realistic source we could integrate without paying for an API. We're working on adding broader web sources.
The scan runs entirely in your browser. We don't keep the text unless you choose to save the scan to your account.
Not yet — there's a beta indicator we're building for the Premium plan, but treat any AI-detection score as a guess for now.
Yes. The checker reads .txt, .pdf and .docx in the browser. Nothing is uploaded to a server.
