Frequently Asked Questions

What type of diff algorithm is used?
RAW uses a line-level diff algorithm that identifies insertions, deletions, and modifications between two texts. Each line is compared to find the minimal set of changes.
Can I compare code files?
Yes. The diff tool works with any text content including source code, JSON, YAML, SQL, markdown, and plain text. The monospace font makes code comparison easy to read.
Is there a size limit?
There's no hard limit. Since the comparison runs in your browser, it can handle large files. Very large files (10,000+ lines) may take a moment to process.
