Checks the live public web in real time. We keep no database of student papers, and results are a guide for review - not proof. How it works

Evidence you can put on the table

A percentage alone is not something you can discuss with a student. The report here links every matched sentence to the exact public web page it matches and shows both texts side by side - the student's sentence and the source's - with exact and near matches marked separately. That is a document you can walk through together.

Patchwriting shows up especially clearly: an essay stitched from several web pages appears as several distinct sources in one report, each with its own share of the document.

A match is a starting point for a conversation - not proof

We print this on every report, because it is true: a match can be a missed citation, a correctly quoted source, a stock phrase of the field, or the student's own earlier work published online. The tool finds overlap; judging what the overlap means is teaching, and no percentage should replace it.

Equally honest: we check the live public web, not paywalled journals or private submission archives. For the most common case - copying from the open web - a live-web check is the right instrument. For archive matching, your institution's licensed system is the only real option.

Grading season volume

A free account covers day-to-day spot checks. For whole-class volume, credits meter by words - 1 credit per 1,000 words - so a small pack covers a stack of papers without a subscription. Multi-file upload is on the roadmap; the credit math will not change.

Frequently asked questions

Paste the passage (or the whole paper, up to 3000 words on a free account) and run the check. The report highlights matched sentences and links each one to the exact public web page it matches, with the source text side by side - evidence you can actually show the student, not just a percentage.

No, and we print that on every report. A match is a starting point for a conversation: it can be a missed citation, a correctly quoted source, a common phrase, or the student’s own earlier work published online. The side-by-side view exists precisely so you can judge the overlap yourself.

Patchwriting spread across multiple sources. The checker aligns every sentence against every retrieved source, so an essay stitched from five different web pages shows up as five distinct sources in one report - the pattern that is hardest to spot by reading and quickest to see on a highlighted report.

Honestly: no. We check the live public web. Paywalled databases and private submission archives are only visible to tools that license them (Turnitin and the institutional systems). For public web copying - by far the most common kind - a live-web check is exactly the right instrument.

One paper at a time works on the free tiers (8 checks a day with an account). For grading season, credits meter by volume: 1 credit per 1,000 words, so a $4.99 pack covers about 30,000 words of student work, and larger packs scale from there. Multi-file upload is on the roadmap.
