TagsGPT does one thing: it generates hashtags for short-form social posts across Instagram, TikTok and YouTube Shorts.
Hashtag selection is a genuinely awkward task – the tags that describe a post accurately are often too competitive to surface it, and the ones that would surface it are too niche to carry traffic. Generating a set automatically per post removes the habit of pasting the same block of tags onto everything, which is the pattern that stops working fastest.
Covering all three short-form platforms in one tool is sensible, since creators generally post the same content to all of them. It is a single-purpose utility and priced as one – expect it to sit alongside a caption tool and a scheduler rather than replace either.
