How to compare two texts
- Paste the original on the left and the changed version on the right, or open a text file.
- Differences appear right away: red is removed, green is added, and changed lines show the exact words that differ.
- Turn on “Only show changes” for long documents, or ignore spaces and case to focus on real edits.
Frequently asked questions
Is my text uploaded anywhere?
No. The comparison runs entirely in your browser, so confidential contracts and code never leave your device.
Can I compare Word or PDF files?
Open the document, select all, copy and paste the text here. The tool reads plain-text files such as .txt, .csv or .md directly.
What does “Ignore spaces” do?
Lines that differ only in spaces, tabs or indentation are treated as the same, which helps when text was reformatted.
When should I highlight characters instead of words?
Use characters to spot single-letter typos or changed digits in numbers; use words for normal editing.
