Counts are strict: every emoji counts as at least 2 characters, so each bio fits X's 160-character limit however the profile editor counts it. Everything runs in your browser.

What is a Twitter bio generator?

A Twitter bio generator turns a few facts about you into ready-to-paste X profile bios. The bio is the 160-character text under your name, and it tells visitors who you are, what you post about, and why they should follow.

This generator writes 12 bios at a time from what you do and what you offer, in 4 tones, 6 profile types and 4 formats. Each bio is built to fit, so nothing is cut off. Here is one from the AI newsletter writer example:

How to write a Twitter bio with this tool

1
Describe your profile
Type what you do and what you offer. Add a company or @account, what you post about, a credential, a personal touch, or a hashtag if you want them.
2
Pick a style
Choose a profile type, tone, call to action, format and length. Bios update instantly; press More ideas for a fresh set.
3
Copy and check
Copy one bio or all 12, grab a Name field idea, or send a bio to the checker before you paste it into Edit profile on X.

What makes a good X bio

Strong bios answer three questions in order: who are you, why follow you, and what should I do next. Here is a founder bio from the generator, split into its parts.

🚀 Founder @ledgerly. 🏆 2x founder. 💰 Building the simplest invoicing app for freelancers. 💬 All things SaaS, pricing & bootstrapping. 🔗 Get started ↓

154/160 characters · 5 lines

Who you are: Founder @ledgerly.
Proof: 2x founder.
What you offer: Building the simplest invoicing app for freelancers.
What you post about: All things SaaS, pricing & bootstrapping.
Call to action: Get started ↓

Lead with your main keyword. It is the first thing people read and the word they search for.
Show, don't claim. "2x founder" says more than "passionate entrepreneur".
End with one call to action, and point it at your Website link.
Use one emoji per idea at most, and keep keywords in plain letters.

X profile character limits

The bio is one of several profile fields. Use each for what it does best, and save your 160 bio characters for words.

Field	Limit	Notes
Bio	160 characters	Same for free and Premium accounts. Spaces, emojis and line breaks count.
Name	50 characters	Shown in bold above your @username. Spaces and emojis allowed.
Username	Up to 15 characters	Letters, numbers and underscores only. It is also your profile address.
Location	30 characters	Free text shown under your bio. A city, region or "Remote" all work.
Website	100 characters	One link, shown under your bio. The best home for your main link.
Pinned post	1 post	Stays at the top of your profile. Use it to expand on your bio.

What is clickable in an X bio

@mentions link to that account, which makes them useful for a company or side project.
#hashtags open a search for the tag.
The Website field shows one link under your bio. Put your main link there rather than typing a web address into the bio, where it uses its full length from your 160 characters.

Calls to action for every tone

Each profile type picks a default: Creator uses Follow, Founder and Brand use Link below, Freelancer uses Hire me, and Employee uses Views my own. Follow lines mention your first topic, shown here as "AI".

Call to action	Professional	Witty	Minimal	Bold
👉 Follow	Follow for more on AI	Follow for more AI takes	Follow along	Follow for AI.

Check your bio before you post

Check my bio counts characters strictly, lists hashtags, mentions and web addresses, and checks for your keyword. Here is what it says about this bio, with the keyword "AI tools":

AI writer | Posts about AI tools, prompts & automation | Newsletter: alexwrites.com #AI #ChatGPT #Automation

108/160 characters · 3 hashtags · 1 web address · keyword found

Move the web address to the Website field (up to 100 characters). It shows as a link under your bio and leaves your 160 characters for words.
Keep it to one or two hashtags. More looks spammy and crowds out the words people search for.

Bio limits on other apps

Reusing your X bio elsewhere? It fits Bluesky as is, needs a small trim for Instagram and Threads, and needs cutting in half for TikTok.

Platform	Bio limit	Notes
X (Twitter)	160 characters	This generator.
Instagram	150 characters	Line breaks are common. Open the generator
Threads	150 characters	Shares one bio with your Instagram profile.
TikTok	80 characters	Half an X bio, so keep only the identity and call to action.
Bluesky	256 characters	Room for an X bio plus extras.
LinkedIn headline	220 characters	Job-focused wording works better. Open the generator

Frequently asked questions

Writing a bio, the 160-character limit, emojis, links, hashtags, the Name field and checking a bio before you post.

How do I write a good Twitter bio?+

Start with what you do in plain words, add what you post about or what people get from following you, add one piece of proof if you have it, and end with one call to action. Keep your main keyword near the start, because X's People search matches names, usernames and bios.

How many characters can a Twitter bio have?+

160 characters, including spaces, emojis and line breaks. The limit is the same for free and Premium accounts. Every bio this generator writes fits.

Does the generator cut bios off?+

No. It builds each bio to fit the length you choose, dropping optional parts such as a personal touch, hashtag, proof or topics when space runs out, so every bio ends cleanly instead of trailing off.

Do emojis count as more than one character in an X bio?+

Some do. Flags, skin tones and emojis built from several pieces can use 2 or more characters, and counting rules differ between apps. This generator counts every emoji as at least 2 characters, so its bios fit however the profile editor counts them.

Can I put a link in my X bio?+

Use the Website field. It holds one link of up to 100 characters and shows it under your bio. A web address typed into the bio uses its full length from your 160 characters, so pair a short call to action such as "Start here ↓" with the Website link instead.

Are @mentions and #hashtags clickable in a Twitter bio?+

Yes. An @mention links to that account and a #hashtag opens a search for it. A mention of your company or project is a common way to send visitors to a second profile.

What should go in the Name field?+

Your name, plus a keyword or emoji if it fits. The Name field holds up to 50 characters and appears in bold above your @username. The generator suggests Name field ideas such as "Alex Morgan | AI Writer".

What is the difference between my name and my username on X?+

Your name is the display name, up to 50 characters, and can include spaces and emojis. Your username is your @handle, up to 15 characters of letters, numbers and underscores. Changing your username changes your profile address.

Is it a Twitter bio or an X bio?+

Both names mean the same field. Twitter was renamed X on July 24, 2023, and x.com became the main address on May 17, 2024. Many people still search for Twitter bio ideas, so this page uses both names.

How many hashtags should I put in my bio?+

One or two at most. Each hashtag is a link away from your profile, and several in a row look spammy and crowd out the words people search for. The bio checker warns you when there are more than two.

Can I check a bio I already have?+

Yes. Choose Check my bio and paste it. You'll see the strict character count, lines, emojis, hashtags, mentions and web addresses, whether your keyword appears, and suggestions to fix anything.

Is the Twitter bio generator free and private?+

Yes. It runs in your browser, needs no account, and sends nothing to a server.

Check your bio before you post

Check my bio counts characters strictly, lists hashtags, mentions and web addresses, and checks for your keyword. Here is what it says about this bio, with the keyword "AI tools":

AI writer | Posts about AI tools, prompts & automation | Newsletter: alexwrites.com #AI #ChatGPT #Automation

108/160 characters · 3 hashtags · 1 web address · keyword found

Move the web address to the Website field (up to 100 characters). It shows as a link under your bio and leaves your 160 characters for words.
Keep it to one or two hashtags. More looks spammy and crowds out the words people search for.

Bio limits on other apps

Reusing your X bio elsewhere? It fits Bluesky as is, needs a small trim for Instagram and Threads, and needs cutting in half for TikTok.

Frequently asked questions

Writing a bio, the 160-character limit, emojis, links, hashtags, the Name field and checking a bio before you post.

How do I write a good Twitter bio?+

How many characters can a Twitter bio have?+

160 characters, including spaces, emojis and line breaks. The limit is the same for free and Premium accounts. Every bio this generator writes fits.

Does the generator cut bios off?+

No. It builds each bio to fit the length you choose, dropping optional parts such as a personal touch, hashtag, proof or topics when space runs out, so every bio ends cleanly instead of trailing off.

Do emojis count as more than one character in an X bio?+

Can I put a link in my X bio?+

Are @mentions and #hashtags clickable in a Twitter bio?+

Yes. An @mention links to that account and a #hashtag opens a search for it. A mention of your company or project is a common way to send visitors to a second profile.

What should go in the Name field?+

What is the difference between my name and my username on X?+

Is it a Twitter bio or an X bio?+

How many hashtags should I put in my bio?+

One or two at most. Each hashtag is a link away from your profile, and several in a row look spammy and crowd out the words people search for. The bio checker warns you when there are more than two.

Can I check a bio I already have?+

Yes. Choose Check my bio and paste it. You'll see the strict character count, lines, emojis, hashtags, mentions and web addresses, whether your keyword appears, and suggestions to fix anything.

Is the Twitter bio generator free and private?+

Yes. It runs in your browser, needs no account, and sends nothing to a server.
