Regex, diffs, and text cleanup for everyday writing

Writers, support teams, and developers all wrestle with text: patterns in logs, two versions of a policy, or a title that must become kebab-case.

Test patterns safely

Regex Tester lets you try an expression against sample text and see matches immediately. Keep personally identifiable examples out of the field when you can; synthetic samples are usually enough to debug a pattern.

Compare two drafts

Text Diff highlights line-level changes between versions of a README, email, or terms snippet. It is a lightweight alternative to opening a full Git UI for a one-off comparison.

Counts and casing

• Word Counter for briefs, captions, and SEO limits.
• Case Converter for camelCase, snake_case, titles, and more when renaming fields or headings.

Editorial hygiene

1. Paste only what you need to transform.
2. Copy the result out, then clear the tool if the text was confidential.
3. Prefer your primary editor for long-form writing; use these tools for precise transforms.
