How to use Text Diff: examples and checks

This guide explains the inputs, worked example and review checks for Wrowo Text Diff. Open the tool overview or start the free workspace.

Compare two texts and see lines added, removed or kept.

How this tool works

A longest-common-subsequence comparison aligns unchanged lines. Output begins unchanged lines with two spaces, additions with + and removals with -. It is useful for reviewing edits before replacing an important document.

Use it in three steps

1. Open the workspace and enter your input. The sample provides a safe starting point with no personal data.
2. Adjust the visible settings, then run the utility. Validation errors explain which input needs attention.
3. Check the output against your task. Copy the text or download the generated file when you are satisfied.

Your result depends on the supplied input and settings. Compare it with your original before using it.

Limits and responsible use

Limited to 300 lines per side. This is a line comparison, not a semantic or legal comparison.

Privacy and output

Processing takes place in this browser workspace. The tool does not call a model API or upload the supplied text or image. Results are temporary until you copy or download them; reloading the page clears the working session. Website account and contact forms are separate from the utility and are explained in our Privacy Policy.
