Frequently Asked Questions
How does the text comparison work? ▼
The tool uses a longest common subsequence (LCS) algorithm to identify differences between two texts, highlighting added lines in green and removed lines in red, similar to how git diff works.
Is there a size limit? ▼
For best performance, each text should be under 5,000 lines. Very large texts may slow down your browser tab during the comparison calculation.
Can I compare code files? ▼
Yes. The diff tool works with any plain text including source code, JSON, XML, configuration files, Markdown, and prose documents. Paste the content directly from your files.
