Social Media Bio Generator

Every profile field has a hard limit and most bio generators ignore it, so what you paste in gets cut off by the app rather than by you. This writes to the limit — 150 characters on Instagram, 160 on X, 220 for a LinkedIn headline — and drops whole sections rather than half a sentence when it has to. The more important rule is what it will not do: it never writes that you are award-winning, certified, or leading anything. Every claim in the bio is a word you typed; only the phrasing around them is generated.

What this generator does

Assembles an opening line, a location, your interests and a closing line into a bio, then drops whole sections from the end until it fits the field's limit. The finished text is checked for length, for containing what it says it contains, and for credential words you did not type.

How to use this tool

Choose where the bio is going.
Type what you do and the field you do it in — both are used word for word.
Add a name, a location and a few interests if you want them.
Write, and run it again for a different arrangement of the same facts.

Understanding the controls

Where it is going: Seven fields, each with its own published limit and its own convention — some are written in the first person, an author bio and a résumé summary in the third.
What you do: Required, and used exactly as typed. This is the one thing a bio cannot be written without.
Field or subject: Required. What the work is about, as distinct from what you are called.
Your name: Only appears in the third-person forms, where a bio has to name its subject.
Where you are: Optional. Dropped first when the bio has to be shortened.
Interests: One per line. At most three reach the bio, and which three varies, which is what makes running it again worthwhile.
What you want people to do: Optional closing line, used exactly as typed rather than rewritten.

Common use cases

Filling a profile field that has been empty for two years
Rewriting the same facts for a different platform and its limit
Getting a third-person author bio out of first-person notes
Fitting a LinkedIn headline into 220 characters without guessing
Seeing several arrangements of the same information before picking one

How this generator works

The limits are the platforms' own, and they are what the bio is built against: sections are dropped from the end until the text fits, so it ends on a full stop rather than mid-word. Where even the opening sentence is too long, the page says so and tells you which field to shorten instead of truncating your job title. The credential check runs over the finished bio against a list of standing-claim words — award-winning, certified, leading, years of experience — and fails the bio if one appears that you did not type yourself. Phrasing is invented because voice is not a factual claim; nothing that reads as a fact about you is.

Randomness and fairness

Which opening, which phrasing and which three interests are used are drawn with your browser's cryptographic random source, so the same facts give a different bio each run. There is no seed.

For how randomness is produced across the whole site, see how Generate Random works.

Limitations and good to know

It writes from what you give it, so a bio with nothing in it but a job title will be short. That is the honest result rather than a failure.
Limits change: platforms have moved them before and the numbers here are what the fields allowed when this page was written.
The dating and résumé limits are conventions rather than enforced maxima, and are set to what still reads well in the space.
It will not write a claim about your standing even if it is true — type it yourself and it will be used.
One language, and one register: plain, slightly dry English. It does not do jokes on request.

Privacy and your data

Everything you type stays in your browser and is used only to compose the text on screen. Nothing is uploaded or stored, and the analytics event carries the platform and a character count — never any word of the bio.
