Plagiarism Checker for Teachers

Teachers spend hours grading student work, and plagiarism detection shouldn't add to that workload. Institutional tools like Turnitin are powerful but often require IT setup, account management, and sometimes per-scan costs that come from departmental budgets. For quick checks on suspicious submissions -- or as a supplementary tool alongside institutional software -- teachers need something fast, free, and immediately accessible.

Coda One's Plagiarism Checker for Teachers lets you paste student text and get results in seconds. No institutional login required, no LMS integration needed, no cost per scan. The tool returns an overall originality score, matched source URLs showing where content was potentially copied from, and a per-sentence analysis that highlights exactly which passages are flagged. This gives you concrete evidence to reference when discussing academic integrity with students.

The per-sentence analysis is particularly valuable for teachers. Instead of a binary "plagiarized or not" result, you can see which specific sentences match online sources and which are genuinely original. This distinction matters because students often mix original writing with copied passages. You can identify exactly where the copying occurred, see the source URL, and have an informed conversation with the student about those specific passages rather than making a general accusation. The tool is free to use and processes text immediately -- no waiting for batch results.
