Text Diff Checker

Compare Text Files and Code Snippets Online

Manually finding the difference between two text files is prone to human error. Whether you are a developer checking code versions, a writer looking for editorial changes, or a student checking for plagiarism, our Text Diff Checker automates the process using the LCS (Longest Common Subsequence) algorithm.

Why compare text client-side?

• Security: If you are comparing sensitive code or legal documents, you don't want that data sent to a server. Our tool runs 100% in your browser.
• Speed: Instant results with no upload wait times.
• Privacy: No data logs, no history tracking.
