Instagram Hashtag Counter

Counts the unique hashtags in a pasted Instagram caption, flags any that are repeated, and warns you once the unique count passes Instagram's 30-hashtag-per-post limit.

Paste your full caption into the box; the unique hashtag count, a red warning if you're over the limit, and any duplicate hashtags all update immediately below it.

For the caption "New drop today #NewArrivals #sale #newarrivals #shoplocal #limitededition", the tool reports 4 unique hashtags — because #NewArrivals and #newarrivals are the same hashtag once case is ignored — and flags #newarrivals as the duplicate.

The scanner looks for a `#` followed by Unicode letters, numbers, or underscores, so accented letters and non-Latin scripts are matched, unlike simpler ASCII-only hashtag patterns. Hyphens are not included, so "#golden-hour" is read as the hashtag "#golden" followed by separate text.

Two hashtags count as the same one if they match after lowercasing, so "#Sale" and "#sale" are treated as one unique hashtag and the second occurrence is listed as a duplicate — this mirrors how Instagram treats hashtags as case-insensitive.

The 30-hashtag limit checked here applies to a single caption or comment as documented by Instagram; this tool only counts what you paste and can't tell whether your hashtags will go in the caption itself or a follow-up comment. It also doesn't check whether any hashtag is banned, shadowbanned, or currently allowed by Instagram — only how many unique ones you've used.

Counting happens entirely in your browser as you type — your caption is never uploaded anywhere.
