Text Similarity Checker
This tool measures how similar two texts are using three complementary algorithms. Levenshtein similarity measures character-level edit distance — useful for detecting typos or near-duplicate strings. Jaccard similarity compares word sets — good for detecting paraphrasing. LCS (Longest Common Subsequence) measures shared character order — effective for detecting reordered content. No text leaves your browser.
