You have two versions of the same text — an email, a contract clause, a job listing, a product description — and you need to know what's different. Reading them side by side is tedious and you'll miss small changes. A word-level comparison tool catches everything.
How it works
ChangeChecks compares both texts word by word and highlights every change. Removed words appear in coral with a strikethrough. Added words appear in sage with an underline. The summary bar tells you how many changes there are, how many words were added or removed, and how similar the texts still are.
The summary tells you what happened before you read anything
Most comparison tools dump you straight into a wall of highlighted text. ChangeChecks starts with a summary: how many change regions, how many words removed, how many added, and the overall similarity percentage. A context line tells you where the changes are concentrated — quoting the actual text near the biggest changes.
This means you often don't need to read the full comparison. The summary answers the question "what changed?" and you only drill into the diff if you need to see the specifics.
Two ways to view
The merged view shows one continuous text with changes marked inline — like Track Changes in Microsoft Word. This is the default and the easiest to read.
The side-by-side view puts the original on the left and the revised on the right, with corresponding sections aligned. Changed words within each section are highlighted in bold.
Fine-tuning the comparison
Common uses
Checking what changed in a revised email or contract. Comparing job listings to see if requirements changed. Verifying that copy was transferred correctly between systems. Proofing translated text against the original.
