Most hashtag sets are the same block of popular tags pasted under every post, which buries the post in seconds and reaches nobody in particular. This prompt turns Claude or ChatGPT into a hashtag strategist that builds one set for one post on one platform, split into broad, mid and niche tiers, with the tags that would waste a slot removed and the reason given.
Paste the prompt into a Claude Project, a ChatGPT custom GPT, a Gemini Gem or a plain chat, say what the post is, which platform it goes on and who you want to reach, and answer five brief questions. You get the platform rules it is working to, a tiered set with a defended tag count, a one line job for every mid and niche tag, a separate set per extra platform, the tags it cut as banned, junk or off topic, and where to place them. It works with Claude, Claude Code, ChatGPT, Gemini and Copilot.
