Generate Better Keywords & Hashtags

Social Keyword Generator is a free suite of six AI-assisted research tools for people who publish on social media and the web every day. Instead of guessing which hashtags to attach to a post or which phrases people actually type into YouTube, you type your topic once and get a structured list of keyword and hashtag suggestions you can copy, edit and use immediately.

The suite covers the four places where discovery actually happens for most creators: Instagram hashtags, TikTok keywords and hashtags, YouTube keywords and video tags, and classic search engine keywords for websites and blogs. There is a sixth general-purpose hashtag tool for any platform we do not cover with a dedicated generator. Every tool is free, requires no account, and puts no limit on how many times you can generate a list.

How the tools work

Pick the platform you are publishing to

Each generator is tuned to one platform. Instagram and TikTok reward different hashtag mixes, YouTube cares about the words people say and type into search, and a website needs keywords that match search intent. Choosing the right generator first matters more than the wording you type in.

Describe your topic the way your audience would

Write a short, plain description of what the content is about: for example cold brew coffee at home, or beginner trail running shoes. Do not stuff it with commas or try to write a list of keywords yourself. One clear phrase gives the model more to work with than a fragmented set of words.

Read the list and cut it down

A generated list is a starting point, not a finished campaign. Delete anything that does not describe your actual content, remove hashtags that are too broad for a new account, and keep the ones you would genuinely expect your audience to search for. Ten well-chosen hashtags outperform thirty random ones.

Test, measure and iterate

Copy the list into your post, then look at your platform analytics after a few days. Instagram and TikTok both show which hashtags drove impressions. Keep the hashtags that work, drop the ones that do not, and regenerate for your next post with the same topic.

Why this site exists

Most keyword tools are built for agencies with a monthly budget. They are excellent, but they assume you already know what a keyword difficulty score is and you are willing to pay before you can see a single result. Many creators Just want a straight answer to a simple question: what should I write in the caption, the title or the tags?

This site is deliberately narrow. It does one job, it is free, and it does not ask you to create an account to do it. There is no paywall in the middle of the workflow and no email capture before you see results. The site is supported by advertising, which is why you see ads on the page, and that is the only trade we ask of you.

Because the tools are free, we also think it is fair to be transparent about how they work. The generators use large language models from Google's Gemini family, called directly from our own server. Your topic is sent to the model, a structured list comes back, and nothing about your request is stored on our side after the response is returned.

What each generator is for

Instagram hashtag generator

Built for feed posts, Reels and carousels. Instagram now reads the words in your caption as well as your hashtags, so the generator returns a mix of broad, mid-size and niche hashtags that you can combine with a keyword-rich caption instead of relying on tags alone.

TikTok hashtag generator

TikTok uses hashtags as one signal among many, alongside watch time, replays and audio trends. This generator leans towards a smaller set of highly relevant and currently trending tags rather than a long block of thirty, because that matches how TikTok distribution actually behaves.

YouTube keyword generator

YouTube ranks on viewer satisfaction more than on metadata, but the words in your title, description and spoken audio still decide who sees the video in search and suggested feeds. This tool returns search phrases people realistically type, plus the variations worth including in your description.

YouTube tag generator

Tags are a secondary signal, yet they still help YouTube disambiguate a video when the audio or the visuals are unclear. The generator returns a weighted set: your exact target phrase first, then broader categories, then long-tail variations and common misspellings.

SEO keyword generator

Aimed at websites and blogs. It produces longer, four-to-six word phrases where search intent is clearer and competition is lower, which is the range a new site can realistically rank for before it builds authority.

Free hashtag generator

A general-purpose fallback for any platform we do not cover with a dedicated tool, including LinkedIn, Pinterest, Threads, X and Mastodon. It returns a broad hashtag set you can adapt by hand to the norms of whichever platform you are posting to.

Common questions

Is the site really free?▼

Yes. All six generators are free and there is no account, no trial and no usage cap. The site earns money through advertising, which is why ads appear alongside the tools.

Do I need to sign up?▼

No. There is no registration step anywhere in the workflow. You open a tool, type your topic and get a list. We do not ask for an email address to show results.

How many keywords can I generate?▼

There is no limit enforced by us. You can generate as many lists as you want, on as many topics as you want, as often as you want.

Can I use the results commercially?▼

Yes. The keyword and hashtag lists are suggestions, not licensed content. Use them in your posts, videos, client work or marketing campaigns without attribution.

Why do different runs give slightly different lists?▼

The generators use language models, which are probabilistic. The same topic can produce a list in a different order or with a few different suggestions each time. That variability is useful when you want alternative angles for a topic you have already covered.

Is my topic or search text stored?▼

Your topic is sent to the language model to produce the list, and the response is returned to your browser. We do not build a personal profile from your searches and we do not require an account that would tie searches to you.
