About this tool
The generator asks Claude, an AI model, for hashtags that match the topic of your post, mixing popular tags with narrower ones where you have a better chance of being seen. Tags are written without spaces or punctuation and avoid banned or spammy tags the AI knows about.
Describe your post or niche, choose the platform and how many tags you want, and run it. The tags come in groups on separate lines, ready to paste. Use a handful per post, not the maximum, and mix at least one narrow tag that really describes the content.
The description box takes up to 1,000 characters. The AI has no live data on which tags are trending, banned or popular today, so check a tag by searching it on the platform before you use it. Platforms change their hashtag guidance often. The list is AI-generated, so remove any tag that is irrelevant or misleading.
Frequently asked questions
How many hashtags should I use?
It varies by platform. A few well-chosen tags usually work better than a long block. For Instagram, 3 to 10 relevant tags is a sensible range; for LinkedIn and X, one to three. Check each platform's current guidance.
Does it know which hashtags are trending?
No. It has no live data. It suggests relevant tags from general knowledge. Search each tag on the platform to see recent posts and make sure it is not banned or used for something unrelated.
How much text can I use, and are there limits?
Each run accepts up to 1,000 characters for the post or niche description. There is also a fair-use limit on AI runs per visitor each day so the tool stays free. When you reach it, the free tools that do not use AI still work, and you can run this one again the next day.
How accurate is the AI output?
No AI output is guaranteed accurate. This tool can misread your meaning, repeat a common phrase or state a detail you did not give it, so read the hashtags through, check every name, number and claim, and edit it before you publish. Treat it as a fast first draft that you review, not finished copy.
