AI bio generator for Instagram, LinkedIn and TikTok

Say who you are, what you do, for whom and what sets you apart, and get ready-to-use bio options within each network's character limit, in a professional, relaxed or inspiring tone. Free, just your email.

How to use

Describe yourself or your brand

Who you are, what you do, for whom and what sets you apart. City, years of experience and how to get in touch help make the bio concrete.

Pick the network and the tone

Each network has a limit: Instagram 150 characters, TikTok 80, X 160, YouTube 300 to 600. For LinkedIn you get a Headline of up to 120 characters and an About of up to 900. Professional, relaxed or inspiring tone.

Copy the one that fits best

The options come numbered, saying what you do, for whom and a reason to follow. Copy, paste into your profile and tweak a word if you like.

Frequently asked questions

What does the bio generator deliver?

Numbered bio options for the chosen network, each saying what you do, for whom and a reason to follow, with a call to action when it fits. No emojis and no hashtags: you add them if you want.

Does the bio respect the Instagram character limit?

Yes. Our AI engine is instructed to write within each network's limit: 150 characters on Instagram, 80 on TikTok, 160 on X and 300 to 600 on YouTube. Check the count when you paste it into your profile: each network counts spaces and line breaks its own way.

How does it work for LinkedIn?

For LinkedIn each option comes in two parts: a Headline of up to 120 characters (role, who you help and the result) and an About of up to 900 characters, in the first person, with three short paragraphs and a closing line on how to get in touch.

Is it free? Do I need an account?

Free: you sign in with just your email (a 6-digit code, no password) and get 3 generations per day, with descriptions up to 6,000 characters. With Rollin Ferramentas Pro there is no daily limit and the text can be up to 15,000 characters.

Which tone should I choose?

Professional for company profiles, consultants and fields like health, law and finance. Relaxed for creators, shops and young brands. Inspiring for coaches, educators and purpose-driven profiles. If in doubt, generate all three and compare.

Does the AI make up numbers or achievements?

No. The bio uses only what you wrote. If you want "10 years of experience" or "over 500 clients served" in the bio, put it in the description; the AI will not create those facts.

Can I generate a bio in Portuguese or Spanish?

Yes. The result comes out in the language of the page: use the Portuguese or Spanish version of the generator for an international profile. The description can be written in any of the three languages.

Is my text stored?

No. The description is sent encrypted, used only to generate the bios and discarded. We keep only a record that the operation happened, to count the daily quota.
