How does the hashtag generator work?
Write a short description of your post or topic and the tool returns 3 groups of hashtag ideas. The first group is broad tags that describe the general subject, the second is niche tags that are more specific, and the third is community or format tags, such as tags for a series, a type of content or a group of people who talk about the subject.
Mixing the three lets you describe a post at different levels instead of repeating one general tag. The tool takes up to 1,500 characters, does not store your text and gives 5 free runs a day without sign-up.
Does the tool know which hashtags are popular?
No, and it is honest to say so. It does not have live data about how many posts a tag has or how often it is used right now, and it cannot tell you which tag will reach more people. It suggests tags that are relevant to what you wrote, based on language patterns, not on platform statistics.
That makes your own check an essential step. Search each tag on the platform you are posting to and look at what appears under it. Make sure it means what you think it means, that the posts under it match your topic, and that it is not used for something you would not want to be associated with. If you want to see what people are talking about on X at the moment, the Twitter trends page shows current topics.
How many hashtags should you use?
There is no single right number, and platforms change their advice over time, so follow what the platform currently recommends and what feels natural for your content. A few well-chosen, relevant tags are usually more readable than a long block that looks like spam.
Place them where they belong on your platform. On Instagram many people put them at the end of the caption, on X they usually sit inside or at the end of the post and share the 280-character limit. Avoid tags that do not describe your post, because they confuse readers and can look careless.
How do you choose between broad and niche hashtags?
Broad tags describe the subject for anyone browsing it, but they also attract a large amount of content, so a single post is easy to miss. Niche tags are more specific, so they describe your post more accurately and are used by people who care about that exact topic. Community or format tags connect you to a group or a recurring series.
A balanced set uses a little from each group. Pick the tags that truly describe the post, drop the rest, and keep a list of tags that worked well for your account so you can reuse them. Remember that hashtags are one signal among many, and no tool can promise reach.
What else should you check before using hashtags?
Check spelling and capitalization of multi-word tags. Writing each word with a capital letter, such as #BuildInPublic, makes the tag easier to read and easier for screen readers to read aloud. Do not use styled Unicode letters inside a hashtag, because a styled tag is a different tag from the plain one.
If you are writing a full caption, the Instagram caption generator can draft the text around your tags. For posts on X, xVirals is an AI writing assistant that drafts posts in your own voice, and you review each one before you publish it.

Frequently asked questions
How do I find good hashtags for my post?
Describe your post in the tool, review the three groups of suggested tags and check each one on the platform before you use it. Pick the ones that truly describe your post.
Does the generator show how popular each hashtag is?
No. It does not have live data on tag volumes, so it suggests relevant tags only. Check popularity and meaning on the platform yourself.
What are the three groups of hashtags?
Broad tags for the general subject, niche tags for a more specific angle, and community or format tags for a group or a recurring series.
How many hashtags should I use?
There is no fixed number. A few relevant tags usually read better than a long block, and platform advice changes, so follow the platform's current guidance.
Will these hashtags increase my reach?
Nobody can promise that. Hashtags are one signal among many, and the tool only suggests relevant tags.
Is it free, and is my text stored?
You get 5 free runs a day with no sign-up, shared with the other AI text tools on this site. Your text is not stored.
