Compare texts and find differences
Compare two text versions and see exactly what was added or removed. Processing takes place locally in the browser – even when loading TXT files.

Removed Added Unchanged text remains neutral.
Changes between two versions
A text comparison helps with revised landing pages, editorial approvals and the comparison of CMS exports. Insert the older stand on the left and the new stand on the right. Distant locations appear crossed out, additions underlined. The colors support this marking.
Compare words or lines?
The word comparison is suitable for flow text and minor revisions. It also takes punctuation marks into account. Line comparison helps with structured lists, configurations, and larger sections. A postponed passage can appear as a distance and addition; the tool does not recognize the content significance of a postponement.
With “ignore empty space”, differences in space strings and indentations are unified for comparison. In line mode, the division into lines remains. The output uses the spelling of the newer version for the same units.
Difference to Duplicate Content Checker
Here you can see specific changes to two versions. The Duplicate Content Checker, on the other hand, examines the similarity of two contents. A small difference does not automatically mean that two sides are sufficiently independent. Check purpose, search intention and actual information content.
The TXT report identifies removed sections with minus and added sections with plus. It is a readable change report, not a patch file for automatic application. The CSV export contains all comparison sections with their classification.
Frequent questions
Are Confidential Texts Staying in the Browser?
Yes. The texts and loaded files are not sent to the server for analysis and are not stored permanently.
Can a page remain empty?
Yes. An empty source text shows the entire new version as a supplement; an empty new text shows the old content as removed.
Does the tool check spelling?
No. It compares spellings and text sections. For legibility, you can also use the legibility checker.
Why can a large comparison be limited?
Very different texts can require many comparison steps. The tool breaks off such comparisons with a hint, instead of loading the browser unlimitedly.
