  Word & character count

  Client

Common use cases

• Open regex when you need presets, a JavaScript snippet, and a quick local test harness.
• Use E.164 normalize when pasted phones mix spaces, parentheses, and international prefixes.
• Use text diff when two drafts should be compared as lines or paragraphs, not as JSON structure.
• Use word count for copy limits, reading time estimates, or quick stats on pasted prose.
• Preview Markdown when README or note syntax should render to sanitized HTML before paste elsewhere.

Common mistakes to avoid

• Expecting regex presets to cover every locale

  Presets are common shapes; international phone and name patterns still need your product rules.
