About Text Diff
Text Diff is an interactive client-side developer utility to compare two pieces of text, source code files, or markdown documentation.
It uses the standard Myers diff algorithm to calculate insertion and deletion transformations at the Character, Word, or Line level.
All calculations run entirely in your local browser environment, guaranteeing absolute data privacy for sensitive source code, key logs, or text documents.
