FAQs

What is an AI hashtag generator?

It's a free tool that suggests relevant hashtags for your social media posts. Describe what you're posting about, and it returns a ready-to-use set tailored to your platform, so you don't have to brainstorm them yourself.

How does it work?

Enter your topic or paste your post, choose your platform, and (optionally) your niche. You'll get a grouped set of hashtags you can copy all at once or pick from.

Is the hashtag generator free?

Yes. You can generate up to five times a day for free, with no account or credit card required. To keep going or schedule your posts, you can create a free Buffer account.

How many hashtags should I use?

It depends on the platform. As a rule of thumb: a handful of relevant hashtags beats stuffing in 30. The generator defaults to a sensible count for each platform, and you can adjust it.

Do hashtags still work?

Used well, yes. Hashtags help categorize your content and surface it to people interested in the topic. A focused, relevant set tends to work better than a long generic list.

Can I schedule the posts I create?

Yes. When you find a set you like, send it to Buffer and schedule your post across your social channels.
