How to use the Twitter bio generator
Answer a few questions, get five bios, pick the one that sounds like you on a good day. That's it.
- Pick your account type. Creator, business or personal. A founder, a bookshop and a football fan want very different things from a bio.
- Say what you do and who you want replies from. Use the words people would actually search, like "B2B SaaS" or "pastry chef", not "growth ninja".
- Add the extras. Keywords, one real proof point and the next step you want. Skip the location here, because X has its own field for it.
- Preview, copy, paste. Click Preview to see each bio on a live profile. Copy your favorite, then on X go to your profile, choose Edit profile, and paste it into Bio.
Already have a bio that isn't working? Switch to Improve my current bio, paste it in, and get five sharper versions that keep your facts.

What to put in your X bio
Most people meet you on X through a reply or a repost, then tap your name to decide whether you're worth following. Your bio gets one look.
Like a good Sherlock Holmes scene, people read the clues fast and decide. Give them the right clues:
- What you do, in words people search for.
- What you post about, so they know what lands in their feed.
- One real proof point, if you have one. A number beats an adjective.
- A light next step, like "DMs open" or a pointer to your link.
Don't try to fit your whole life story into 160 characters. Pick the version of you that your ideal follower cares about, and let your posts do the rest.
Name, handle, bio, location: what goes where on X
X gives you several fields, and each has its own limit. Using them properly keeps your bio from doing jobs that belong somewhere else.
| Field | Limit | What to put there |
|---|---|---|
| Display name | 50 characters | Your name plus one plain keyword, like "Maya · B2B SaaS Growth" |
| Username (@handle) | 15 characters, letters, numbers and underscores | Short, easy to spell, easy to say out loud |
| Bio | 160 characters | What you do, what you post about, and why to follow |
| Location | Its own field | Your city, so the bio doesn't have to say it |
| Website | Its own field | Your site or link page, so the bio never needs a URL |
These limits come from X's own profile and username rules help pages. The takeaway: YOUR BIO SHOULD NEVER REPEAT YOUR LOCATION OR WEBSITE. Those fields already show them.
X bio ideas and formulas
Pick a formula, fill in the brackets, or choose the matching vibe in the tool.
Professional
- "[Role] for [audience]. I write about [topic] that [result]." e.g. "Designer for fintech apps. I write about onboarding that people actually finish."
Build in public
- "Building [product] for [who]. Sharing [numbers, lessons or mistakes]." e.g. "Building a booking tool for barbers. Sharing revenue, churn and bad haircuts."
Funny
- "[Job] by day. [Honest hobby] by night. [Self aware twist]." e.g. "Accountant by day. Amateur chef by night. Neither is going well."
Short
- "[Role]. [Topic]. [One word attitude]." e.g. "Nurse. Night shifts. Snacks."
Keywords in your X bio
X search shows posts and accounts together, and people often look for experts by typing a role or a topic. X doesn't publish exactly how account search works, but plain words give you the best chance of matching what people type.
- Use the job title people search, not a clever label. "Product designer" beats "pixel wizard".
- Name your niche. "B2B SaaS" or "climate data" tells both people and search what you're about.
- Put a keyword in your display name too. You have 50 characters there, which is plenty for "Name · Keyword".
Stuffing three job titles and five topics into one bio does the opposite. It reads like a résumé that fell down the stairs.
X bio character limit and formatting
Your X bio can be up to 160 characters. Spaces, emoji and line breaks all count. The counter on every result shows the exact total, so you'll never hit the limit mid paste.
A few formatting habits that help:
- Lead with the most important words. People skim, and the first line does most of the work.
- @mention your company if you have one. It points curious readers straight to it.
- Keep line breaks to a minimum. One or two lines read cleanly under your name.
- Leave out hashtags. They rarely help a bio, and they cost characters you could spend on what you do.
X bio mistakes that cost you followers
- The keyword pile. "Marketing | Growth | AI | Web3 | Coffee" says you can't decide what you are.
- "Views my own" and nothing else. Fine as a closer, useless as a whole bio.
- Repeating your location and link. They already have their own fields.
- A bio that fights your pinned post. If the bio says SaaS and the pinned post is about your cat, pick a lane.
- Clever but unclear. If a stranger can't tell what you do in one read, the joke cost you a follower.
Frequently asked questions
Is this Twitter bio generator free?
Yes. Free to use. Fair use limits apply.
How long can a Twitter bio be?
160 characters, including spaces and emoji. Every bio this tool writes fits, and the counter shows the exact total.
Is a Twitter bio the same as an X bio?
Yes. Twitter became X, and the bio field works the same way. Most people still call it a Twitter bio.
How long can my X display name and username be?
Your display name can be up to 50 characters. Your username can be up to 15, using letters, numbers and underscores.
Should I put my website or location in my bio?
No. X has separate fields for both, so the bio can spend all 160 characters on what you do and why to follow.
Should I use hashtags in my X bio?
Usually not. They take characters away from what you do. If you want topics in your bio, write them as plain words.
Will the AI make up achievements?
No. It only uses what you type. If a bio would be stronger with a real number, it tells you what to add instead of inventing one.
Can it rewrite the bio I already have?
Yes. Switch to "Improve my current bio", paste it in, and you'll get five rewrites that keep your facts.
Can it write X bios in other languages?
Yes. Pick your language from the dropdown and all five bios come out in it.
Your bio gets the click. Your content has to keep them.
