Text compare
Edit, pick a content type and see differences in real time.
100% in browser— No files or data are sent to a server. Everything runs on your device.
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, word or character comparison. The summary shows how many lines were added or removed; the diff panel highlights changes and can collapse identical blocks.
Open or drop any file up to 5 MB into each side, export a unified patch (.diff), copy only the changes, or download each side. Everything runs locally in your browser — your text is never sent to servers.
Frequently asked questions
Which content types are supported?
Plain text, JSON, XML, HTML, CSS, JavaScript, YAML, SQL and Markdown. Syntax highlighting adapts to the selected type.
Can I open files?
Yes. Use “Open file” on each panel or drop any file up to 5 MB. Content is read as text; the type (JSON, JS, Markdown…) is detected from the extension when possible.
How do line, word and character modes work?
Lines show whole blocks added or removed. Words highlight snippets within a line. Characters mark the smallest edits — useful for short strings and dense configs.
Is my text sent to a server?
No. Editing, syntax highlighting and diffing happen entirely in your browser.
