Describe yourself, pick a platform and a tone, and we’ll write a bio that fits its character limit.
Your bio preview will appear here.
We’ll fit it under the platform’s character limit so it never gets cut off.
Our AI bio generator works as a free bio maker and bio creator for any profile. It takes three steps and under a minute, with no login.
Tell the generator who you are, what you do, and who it’s for. A bakery in Portland, a freelance designer, a creator who reviews gadgets. Specific details make a sharper bio.
Choose where the bio is going and one of 10 tones, from professional to witty. The generator keeps it inside that platform’s character limit.
Happy with it? Copy it straight into your profile. Want another option? Click generate again for a fresh bio from the same description.
Every network gives you a different amount of room. Here’s how long a bio can be on each one, and what works best there. The generator follows all of these limits.
| Platform | Character limit | What works |
|---|---|---|
| 150 | Emojis and line breaks welcome. End with a reason to tap your link. | |
| TikTok | 80 | Every character counts. Short, playful, and to the point. |
| X (Twitter) | 160 | One or two clauses that say who you are and what you post. |
| 101 | A friendly intro. Keep emojis to a minimum. | |
| LinkedIn headline | 220 | Lead with your role. No emojis, no hashtags. |
| YouTube channel description | 1,000 | Open with what your channel is about, then who it’s for. |
| Bluesky | 256 | Casual and low-key, like a friendly status line. |
| Mastodon | 500 | Plain and genuine. Marketing speak falls flat here. |
| General | 300 | A short bio you can use anywhere: newsletters, speaker pages, email signatures. |
Mastodon limits can vary by server; 500 characters is the most common.
Whatever the platform, the best bios do these four things. The generator writes with all of them in mind.
Your role, business, or niche belongs in the first few words. Most people decide whether to follow in a second or two.
What will people get from following you, buying from you, or working with you? Make it clear.
A detail that’s only true of you, or an emoji or two where it fits, makes your bio memorable.
Point people to your website, shop, newsletter, or latest launch. A bio that goes somewhere turns visitors into customers.
Need inspiration? Here are eight short bio examples, including professional bio examples for work profiles, with what makes each one work. Borrow the structure, or describe yourself in the generator above for a bio written just for you.
All of these fit Instagram’s 150 characters. Writing a longer professional bio? Choose the General platform and the Professional tone.
Copy any of these into the box above, pick a platform and tone, and see what the generator writes. Then swap in your own details.
“A family-run landscaping company in Denver doing residential and commercial projects since 2012.”
“A YouTuber who reviews budget tech and posts honest buying guides every week.”
“An HR consultant helping startups build their first people team. Ten years at fast-growing companies.”
“A small online shop selling handmade ceramic mugs and plates in earthy colors.”
“A personal trainer who helps new moms get strong again with 20-minute home workouts.”
“A watercolor artist painting coastal landscapes and teaching beginner classes online.”
Tip: the generator only uses what you tell it, so include your real role, audience, and results. “Trainer” gets you something generic. “Trainer for new moms, 20-minute home workouts” gets you a bio you can use.
A great bio brings people to your profile. Hopper HQ is the social media scheduler that keeps it worth visiting, with posts planned and published on Instagram, TikTok, Facebook, YouTube, LinkedIn, X, and Pinterest from one tab.

Yes. This free bio generator needs no login or sign-up, and you can generate as many bios as you like.
It depends on where it’s going. Instagram bios max out at 150 characters, TikTok at 80, X at 160, and LinkedIn headlines at 220. Pick a platform and the generator keeps your bio inside its limit, or choose General for a short bio of up to 300 characters you can use anywhere.
Start with who you are and what you do, add what makes you different, and finish with what you want people to do next, like follow, visit your site, or get in touch. Or let this AI bio generator do it: describe yourself in a sentence or two and it writes the bio for you.
Yes. It works as a professional bio generator for short bios: choose the Professional tone and the General platform for a bio of up to 300 characters, great for speaker pages, newsletters, and email signatures. For LinkedIn specifically, try our LinkedIn Headline Generator.
It’s a social media bio generator for Instagram, TikTok, X (Twitter), Facebook, LinkedIn, YouTube, Mastodon, and Bluesky, plus a General option. Each one gets its own character limit and style. Writing mainly for one network? Each has a dedicated version in the list below.
It depends on the platform. Instagram and TikTok bios get a few emojis, because they suit those feeds. LinkedIn bios never do. Everywhere else, the generator adds one or two only if they fit. You can always edit your bio before you copy it.
No. The generator only uses the details you give it and won’t invent awards, numbers, locations, or links. That’s why a specific description, with your role, niche, and a result you’re proud of, gets you a much better bio.
Click generate again for a fresh bio from the same description, or switch the tone for a noticeably different one. Our bio examples above are another good starting point.
Plan, schedule, and publish across every network from one Hopper HQ tab, so new visitors always find something fresh.
