Writing Pattern Checker
Your writing stays in this browser and is not sent to a model.

Writing to check
The checker uses named rules in this browser. It does not send the text to a model or decide who wrote it.
Review / Exact matches
Pattern review
Paste writing to inspect exact patterns and decide what, if anything, to change.
How it works
- Paste up to 100,000 characters. The text stays in this browser.
- Run the named rule set to see exact source spans and a plain explanation for each match.
- Make your own edits, or explicitly select the limited mechanical em-dash cleanup and copy that result.
Limits
- This is not an AI detector and does not identify who wrote the text.
- The rules are deliberately finite. A clean result is not a quality score.
- The checker shows at most 500 matches so an unusual input cannot flood the page.
- Only the selected em-dash cleanup changes text. The tool does not rewrite your voice.
