Frequently Asked Questions
What is a diff checker?
A diff checker is a tool that compares two pieces of text and highlights the differences between them. It shows which lines or words were added, removed, or changed, making it easy to review modifications.
What is the difference between unified and side-by-side view?
Unified view shows both texts merged into a single view with additions and deletions marked by colors. Side-by-side view shows the original and modified text in two separate columns, making it easier to compare corresponding lines.
What is the difference between line-level and word-level diffs?
Line-level diffs compare entire lines and mark whole lines as added or removed. Word-level diffs compare individual words within lines, giving more granular insight into exactly what changed within a line.
