Frequently asked questions

Simple answers to your questions

How does text-to-text comparison work?
Paste the original text on one side and the new version on the other. WriteSimpli highlights each word or line that was added, removed or changed.
What can I use text comparison for?
Reviewing edits to essays and articles, checking contract wording, comparing translations, or confirming what a co-author changed.
Is text comparison the same as a plagiarism check?
No. Text comparison only compares the two texts you provide. It does not search the web or other sources for matches.
Is there a length limit?
You can compare long passages, including full essays and chapters. For whole documents, the Compare PDF tool may be easier.
