What's in the corpus

Code your students copy from — indexed before they submit.

Web search misses code on Stack Overflow gists, archived repos, and reposted snippets. The corpus catches what Google doesn't.

Public GitHub repositories

Continuously ingested from active public projects — code that lives in starred repos, course solutions, and homework helpers shows up in your match report.

Stack Overflow answers

Top-voted code snippets and accepted answers, indexed at the chunk level — paraphrased copies still match because the corpus is searched by token, not URL.

Private institutional database

Anonymized submissions from academic institutions across the Codequiry network — a private corpus that catches contract-cheating rings and recycled coursework that never appears on the public web.

How it works

Trigram-indexed search built for code, not text.

Sub-second matching across tens of millions of documents. Every scan you run hits the same corpus you can query right above.

Continuously indexed

New repositories and answers ingested daily. The corpus grows ~hundreds of thousands of documents a week — your scans get smarter without any work on your end.

Sub-second matching

Trigram-indexed search returns top matches in under a second even across tens of millions of documents. Your submission gets graded faster.

Noise-filtered

Boilerplate (Supabase clients, framework templates, common stdlib idioms) is filtered out automatically. You see real matches, not "this file imports React."

Built to be trusted

We know code looks similar. Codequiry flags plagiarism with one of the lowest false-positive rates on the market.

Boilerplate, framework templates, common stdlib patterns, and standard imports are filtered before a match is ever surfaced. When Codequiry flags a pair of submissions, you can take it to the academic-integrity committee with confidence.

Every premium plan checks the entire corpus.

2T+ web sources, every public GitHub repo, Stack Overflow, Chegg, CourseHero, and every prior student submission you’ve uploaded — cross-checked in a single pass. Once students learn their code gets compared against everything ever written, the copying stops. Set the deterrent on day one and the integrity problem solves itself.
