❓ Frequently Asked Questions
Does it support hyphenated or apostrophe words?
Yes! The tokenizer splits words while keeping hyphens and apostrophes: "state-of-the-art", "Mom's" are treated as single words.
What's the difference between regex mode and plain mode?
Regex mode unlocks full regular expression syntax (boundaries, quantifiers, character classes). Plain mode is simpler: substring, exact, starts/ends—great for non-technical users.
Can I filter emojis or Unicode?
Absolutely. Word detection uses Unicode property escapes, so words with letters from any language (Arabic, Cyrillic, etc.) are recognized.
Will this tool work on Blogger / WordPress?
Yes, just copy the entire HTML code and paste it into the "HTML view" of your blog post. The tool is self‑contained and responsive.
