Compare two texts using Jaccard, Cosine TF, and Levenshtein methods — visualize word overlap, frequency, and similarity scores
Yes, PivaBox Text Similarity Comparator is completely free to use. All computation runs locally in your browser — your text never leaves your device.
Jaccard similarity only considers whether a word appears (presence/absence), treating all words equally. Cosine TF similarity uses word frequencies, so a word that appears 10 times in both texts contributes more to the score than a word appearing once. Cosine TF better approximates semantic similarity.
Levenshtein distance counts the minimum number of single-character edits (insertions, deletions, substitutions) needed to change one string into another. It is not word-aware — it compares raw text as character sequences, making it ideal for catching typos, minor rewrites, and near-duplicate strings.
