Plagiarism Checker — Local + Third‑Party Embeds

Plagiarism Checker

Two modes: Local similarity check (client-side, compare text/files you provide) and Web-scale check via third-party services (iframe embeds / API links).

Local similarity (fast, private)

Paste the text you want to check, and optionally paste or upload documents to compare against. This runs entirely in the browser — nothing is uploaded.


Web-scale check (recommended for final checks)

For searching the web and large databases use a dedicated plagiarism API/service. Choose a provider below to open their site (you'll need an account/API key for automated checks).

Note: embedding automated web-scale checks requires API keys or paid accounts. I can add integration code for Copyleaks, Turnitin (enterprise), or others if you provide API credentials.
