How to clean hashtags and captions

Short answer

Clean a caption by fixing spacing first, extracting hashtags, removing duplicates case-insensitively, limiting the list, and reviewing the final caption for platform fit before posting.

A practical cleanup order

  1. Normalize spacingRemove accidental extra spaces and repeated blank lines so the caption is readable.
  2. Extract hashtagsPull hashtags into a separate list so duplicates and casing are easier to spot.
  3. Remove duplicatesTreat #AI and #ai as the same tag unless the platform or brand style requires otherwise.
  4. Review before postingThe cleaner organizes text; it does not know current trends, audience fit, or platform enforcement.

Tags are not magicHashtags help categorize content, but title, thumbnail, description, quality, and audience fit usually matter more than a long tag pile.
