Frequently Asked Questions

What kind of files can I compare? +
Any plain-text content: code, JSON, configuration files, Markdown, CSV, or simply two drafts of an email. Binary files are not supported.
Is the tool as accurate as a Git diff? +
It uses a line-based diff algorithm similar to the one Git uses. For most everyday comparisons, the result is equivalent. For word-level or syntax-aware diffs, a dedicated editor like VS Code gives more detail.
Are my texts uploaded? +
No. Comparison is a pure JavaScript computation that runs in your browser. Safe for code snippets containing secrets or proprietary logic.
Can I compare very long files? +
Yes, up to a few megabytes of text. Very large files may slow down the browser because the diff output must be rendered in the DOM.
Does the tool handle line-ending differences? +
Yes. Windows (CRLF) and Unix (LF) line endings are normalized so that differences focus on real content changes, not invisible characters.
