Questions
Which mode should I use?
By line suits code, lists and long documents. By word shows small edits inside sentences.
Is there a size limit?
Very long texts compared word by word can be too heavy for the browser. Compare by line, or in smaller parts.
Is my text uploaded to a server?
No. The tool runs in your browser and works on your text directly on your device. Nothing is sent to us or anyone else, which is why it also keeps working if your connection drops after the page loads.
