Free Text Compare Tool: Find Differences Between Two Texts
Paste two versions of a text to see exactly what changed. Added lines show in green, removed lines in red, and unchanged lines stay plain, so you can review edits in seconds.
How to use the text compare tool
- Paste the original text in the first box.
- Paste the changed version in the second box.
- Read the result. Lines with a green plus were added, and lines with a red minus were removed. A changed line shows as one removed and one added.
- Copy only the changes to share them with a client or teammate.
When comparing texts helps
| Situation | What to check |
|---|---|
| A client sends back edited website copy | Exactly which lines they changed |
| Updating a course or price page | That only the intended details changed |
| Reviewing a contract or proposal | Clauses added or removed between versions |
| Comparing robots.txt or code snippets | Rules or lines that differ between two sites |
| Checking two keyword lists | Which keywords are new and which were dropped |
How the comparison works
The tool compares the texts line by line and finds the longest set of lines they share, the same idea behind developer diff tools. Everything outside that shared set is marked as added or removed. You can ignore spaces at the start and end of lines, or ignore case, so small formatting changes do not hide the real edits.
Tips
- For paragraphs, put each sentence on its own line before comparing to see changes more precisely.
- Clean pasted text first with the extra space remover if formatting differs.
- Both texts stay in your browser, so it is safe for private documents.
