Text compare
Edit, pick a content type and see differences in real time.
Compare versions of code, JSON, XML, HTML, CSS, JavaScript, YAML, SQL or plain text in two panels with syntax highlighting. Ideal for reviewing commits, validating configs, checking API responses or verifying whether two files are identical.
Pick a content type for the right syntax colors and switch between line-by-line or word-by-word comparison. The summary shows how many lines were added or removed; the diff panel highlights changes with colors.
Everything runs locally in your browser — your text is never sent to servers. Use it for quick reviews, debugging and data validation without installing external tools.
