Hashtag Extractor: Frequently Asked Questions

The extractor identifies any string beginning with # followed by word characters. If a URL contains a # (for URL fragments), that portion may be incorrectly identified as a hashtag. This is rare in practice since social posts rarely include URLs with fragments.

The extractor uses the pattern #\w+ which matches letters, digits, and underscores after the # symbol. Hyphens are not valid in hashtags on any major platform. Accented characters (é, ü, ñ) are supported on most platforms and the extractor captures them as part of the hashtag.

Yes. The extractor captures any word characters after #, including accented Latin characters and many non-Latin scripts. Hashtags in Arabic, Japanese, Korean, and other scripts that use non-Latin alphabets are also extracted if the platform supports them.

With deduplication on, each unique hashtag appears only once in the output regardless of how many times it appears in the input. With deduplication off, every occurrence is preserved. Deduplication on is best for creating a tag list to copy into a new post. Deduplication off is best for frequency counting across multiple posts.

If a single post repeats hashtags (e.g., #marketing appears twice), frequency sort shows those repeated tags first. More usefully, frequency sort comes into its own when you paste multiple posts together — it reveals which tags appear most consistently across all pasted content.

Yes — copy any text from any source (bio, caption, story text, comment) and paste it into the extractor. It works on any plain text regardless of where it came from.
