Hashtag Counter
Paste a caption and instantly see how many hashtags it contains, whether that count is within each platform limit, and which tags repeat. Instagram allows up to 30 hashtags per post, TikTok and X are more forgiving but stuffing dilutes reach, so knowing your exact number matters before you publish. This tool scans your text for anything that looks like a hashtag, counts the total and the unique set, and warns when you exceed 30 so you can trim before Instagram silently rejects the extras. It lists every tag it found so you can spot typos and duplicates that waste a slot. All of this runs locally in your browser with nothing uploaded. Drop in your caption, read the count, and tune your tag set for the platform you are posting to.
