Free TikTok Tools: Hashtags, Captions, Usernames and Bios

These free TikTok tools cover the four things every account needs sorted (a username, a bio, captions and hashtags) plus a calculator to price a post. Each one runs in your browser, needs no sign-up and connects to nothing, so you just type what you need and copy the result into the app.

Everything below is free and runs on your own device. Pick the one you need, or work through them in order if you are setting up a new account.

Free TikTok Hashtag Generator

Type your topic and niche and get a relevant, de-duplicated set of hashtags, plus a recommended short set. It uses no trend guesswork, just tags that match your content.

Free TikTok Caption Generator

Pick your goal and get a caption built from a hook, a value line and a call to action, so you start from a real draft instead of a blank box.

Free TikTok Username Generator

Enter your name or niche and a style, and get short, memorable handle ideas you can try in the app.

Free TikTok Bio Generator

Get short bio options that fit the 80-character limit, each with a live character count and one clear next step.

TikTok Money Calculator

Estimate what views and engagement could earn, so you can price a post or set a goal.

Frequently asked questions

Are these TikTok tools really free?

Yes, every one runs in your browser with no sign-up, no account and no payment. Nothing you type is stored or sent to a server. They are here because they are useful and because helping creators is what my site is about.

Do the tools need TikTok login or access to my account?

No. None of them connect to TikTok or ask for your login. You type a topic or a name, the tool builds the result on your own device, and you copy what you want into the app yourself.

Which tool should I start with?

If you are setting up an account, start with the username generator, then the bio generator. If you already post, the hashtag and caption generators help most with each new video. The money calculator is for when you want to price a post or set a target.

Do these work for Instagram Reels and YouTube Shorts too?

Mostly yes, because the shapes of a good caption, bio and hashtag set carry across short video. Swap the platform-specific bits, like the reach hashtags and where you put a link, and the rest holds up.
