Compare Text. Find Every Difference.
Professional comparison without the clutter.
Compare articles, contracts, configuration files and source code with precise, reviewable differences. Edit either side, then merge line-by-line with a single click.
Line-by-line diffing
Every changed line is highlighted the moment you compare, with a clear arrow to merge it either direction.
One-click merge arrows
No separate preview panel — merge directly where you're already reading, just like a desktop diff tool.
Runs in your browser
Nothing is uploaded to a server. Your text and files stay local, compared entirely on your device.
Common questions
Is this text compare tool free to use?+
Yes. XAppForge's text compare tool is completely free, with no sign-up required.
Does my text get uploaded anywhere?+
No. The comparison runs entirely in your browser for pasted text and local text files — nothing is sent to a server.
Can I compare source code, not just plain text?+
Yes. Switch either side to the Code tab, pick a language for reference, and compare line-by-line.
Can I merge the two versions together?+
After comparing, click the arrow between any two changed lines to copy that line to the other side — one click per line, just like a merge tool.
