How to compare two texts online
Paste the original version into the left field and the new version into the right field. Choose line comparison for documents and lists, word comparison for editorial revisions, or character comparison for a precise check of short fragments. Then click “Compare”.
The tool shows whether the texts match, calculates a similarity percentage, and highlights added and removed fragments. View the result as a unified diff, two columns, or a list of changes. You can edit the unified diff and send it to the Textria notebook.
For editors and writers
Review changes after editing an article, approving copy, or updating a product description.
For developers
Compare configuration files, logs, value lists, and text responses without uploading files to a server.
For documents
Find revised clauses in contracts, instructions, requirements, and working notes.
Comparison settings
You can ignore letter case, extra spaces, empty lines, or punctuation. This helps separate meaningful changes from formatting differences. User text is never interpreted as HTML and remains on your device.
FAQ
Frequently asked questions about text comparison
Answers about comparison modes, privacy, and working with the result.
How do I compare two texts online?
Paste the original text into the left field and the new text into the right field, choose a mode and settings, then click “Compare”.
What is the difference between line, word, and character comparison?
Line mode works well for documents and lists, word mode highlights editorial changes, and character mode provides a precise comparison of short text fragments.
Can I ignore case, whitespace, and punctuation?
Yes. You can turn off matching for letter case, extra spaces, empty lines, and punctuation to focus on meaningful content changes.
Are my texts sent to a server?
No. The comparison runs locally in your browser, so the texts you enter are not sent to Textria's server.
Can I edit the comparison result?
Yes. The unified diff is editable. Running the comparison again will replace your manual edits with a newly generated result.
How do I open the result in the Textria notebook?
Select “Unified diff” and click “Open in notebook” below the result. The Markdown report is saved locally and the notebook opens in a new tab.
