The Levenshtein distance (edit distance) measures how similar two strings are by counting the minimum number of single-character edits needed to transform one into the other. The Edit Distance Calculator computes this metric with a summary of operation types.
This tool is useful for spell checking, DNA sequence analysis, natural language processing, and fuzzy string matching. It shows total insertions, deletions, and substitutions required to align the two strings along with a similarity percentage.
Boost your daily productivity with Levenshtein Distance, designed to handle repetitive formatting and conversion tasks in seconds. Instead of switching between multiple applications, get everything done in one place with consistent, reliable results.
String A: "kitten"
String B: "sitting"
Distance: 3
Similarity: 57%
Operations:
Substitutions: 2
Insertions: 1
Insertions, deletions, and substitutions of single characters are all counted as one operation each.
Yes, the comparison is case-sensitive by default. "Hello" and "hello" have a distance of 1.
