When to use it
Use it for edited sentences, README changes, or small JSON/YAML fragments where you need to see what changed.
⚖️ Text Diff Checker
Compare edited text, code snippets, and configuration fragments by character, word, or line.

Choose the level
Character mode helps with typos, word mode helps with wording, and line mode is easier for code or configuration files.
What it does not do
It does not manage Git history or upload files for comparison. Paste the two text versions directly into the panels.
Frequently Asked Questions
▼
Q. Are the texts or documents I compare sent to an external server?
No. They are never sent. This tool works 100% locally in your web browser. Any pasted text, code, contract, or other important data can be compared safely without being exposed to an external server.
Q. Which comparison modes are supported: Character, Word, or Line?
All three modes are supported. Use Character mode for fine typo checks, Word mode for sentence-level wording changes, and Line mode when line-by-line changes matter, such as in source code.
Q. Can I use it for code or configuration files?
Yes. It works well for short functions, JSON/YAML fragments, logs, or other text where line-by-line changes matter. It does not replace Git history or directory-level comparison tools.
Q. Can I swap the original and modified texts?
A one-click swap button is not currently provided, but you can use the paste and clear buttons above each panel to replace the contents and compare again.
Q. Can I copy only the comparison result?
Yes. After comparing, click Copy Result at the top of the result panel. The copied result is designed to provide the changed text content cleanly, rather than visual color styling or formatting metadata.
Q. Can I upload files directly for comparison?
Not currently. Copy the content from each file and paste it into the original and modified text panels, then run the comparison.
