Draft a compact profile bio that states who it helps, how and what to do next. Free to use in your browser; no sign-up.
A profile bio is a small, hard writing problem: about 150 characters to say who you help, what you do and where to go next, in a field that is read in a fraction of a second by someone deciding whether to follow. Every platform has a different limit and a different convention for the link.
Without a key this tool composes a draft from proven formats, filled with what you typed. That runs entirely in your browser and costs nothing. Add a key and the same inputs go to Claude instead, which writes rather than assembles.
Your key is stored only in this browser and is never sent to us, so we cannot see it. Requests go straight from your browser to Anthropic. It is masked here and obfuscated in storage, though anyone with developer tools on this machine can still read their own key back.
Keys come from console.anthropic.com. Usage on your own key is billed to you by Anthropic, not by us.
Cobbett Repairs is one person in a workshop who services and repairs domestic sewing machines sent in by post from anywhere in the country. Vintage machines are most of the work. The inputs handed to the generator were that audience, home sewers with a machine that has stopped working, the mechanism, send it in and get it back, and the next step, a quote form rather than a homepage.
The bio that came out and stayed is three short lines. Sewing machine repairs by post, UK wide. Vintage Singers a speciality. Two week turnaround, quoted before I start. Underneath it, one link, going straight to the quote form. That is around a hundred and ten characters before the link, which means it fits inside the tightest limit with room to spare and does not truncate differently on every platform.
The first line does the recognition work and, more importantly, the qualification work. By post, UK wide tells the person in another county that this is available to them, and tells the person hoping for a local drop off that it is not, before either of them writes a message. The second line is the searchable line: vintage Singers is the phrase people type into the platform's own search, and it is also the phrase that makes the right person feel found rather than marketed at. The third line pre empts the only two questions that ever arrive by direct message, how long and how much, and answers one of them with a policy rather than a price, which is honest and still reassuring.
The link matters as much as the words. It goes to the quote form because the bio promised a quote, and a bio that promises one thing then lands on a homepage hands the visitor navigation work you had just asked them to trust you with. There is no link aggregator, because there is only one thing worth doing.
The bio this account had before is the version most small accounts write: a sparkle emoji, sewing machine wizard, a thread emoji, then Maker, then Mum of three, then Vintage lover, then DM for enquiries, then an arrow pointing down. It is weaker for specific reasons. Wizard is a self awarded compliment occupying space that could have carried a fact, and it never says that repairs are the service. Nothing in it mentions post, so half the enquiries came from people two hundred miles away asking whether they could pop in. Maker, Mum of three and Vintage lover are three category labels that tell a stranger which groups the account belongs to and nothing about whether following it is worth their time. DM for enquiries adds a step, and every enquiry then arrives with no machine model and no description of the fault. The emoji separators cost characters and are read out one by one by screen readers, turning a short bio into a long announcement. The rewrite is barely shorter. It is just made of facts.
Do not write a bio for an account with no decided purpose. If you cannot say what the account is for and who should follow it, the bio ends up as a list of nouns, because a list is what you write when you are describing yourself rather than offering something. Settle the purpose in a sentence first, even a boring one, and the hundred and fifty characters largely write themselves.
Do not ask the bio to fix a positioning problem. A profile that is not attracting the right people usually has a content problem, a consistency problem or an audience problem, and none of those live in the bio field. If the last twelve posts do not make it obvious what the account is about, no arrangement of words at the top will compensate, and rewriting it every fortnight is a comfortable substitute for the harder work of posting things worth following.
Hold off if there is nowhere useful for the link to go. A bio ending in a link to a homepage that says nothing about what was promised loses most of the people who clicked, and it is better to have no link and a clear instruction than a link that disappoints. Build the destination first, even if it is one plain page with a form on it.
Leave personal accounts alone. A bio written to convert on a personal profile reads as though somebody has turned themselves into a business card, and the people it is aimed at were not there to be converted. Similarly, if your offer or your job is genuinely changing month to month, write the bio at a level that stays true across the change rather than editing it constantly, because every rewrite resets the recognition of people who follow several accounts and remember yours by its shape.
The bio is one field in a set, and the set is what a visitor actually processes. The handle is the part people type and misremember, so it wants to be short, spellable from hearing, and consistent across platforms. The display name field is separately searchable on several platforms, which means it can carry the plain words for what you do rather than repeating the handle: on an account called cobbettrepairs, a display name of Cobbett Repairs, sewing machine servicing works harder than Cobbett Repairs alone.
The profile image is read at very small sizes and is doing recognition rather than communication, so a detailed logo with a strapline inside it is wasted. A pinned post or featured highlight is where you put the thing the bio had no room for: the price range, the process, the before and after. Treat the whole block as one composition and stop trying to make the bio field carry it alone. Written that way the bio can be shorter, because it only has to do the part nothing else can do.
The limits differ enough that a single string cannot be pasted everywhere without loss. Instagram gives you a hundred and fifty characters, X a hundred and sixty, TikTok about eighty, which is the one that forces real discipline. LinkedIn splits the job in two: a headline of a couple of hundred characters that travels everywhere your name appears, and a much longer About section truncated after a few lines until somebody expands it. A Facebook page has a short description plus longer fields, and a YouTube channel description is long but only its opening line is visible in most contexts.
So write the eighty character version first and treat it as the spine. Then extend rather than rewrite: the roomier platforms get the same claim plus the proof or the process that would not fit elsewhere. What you are protecting is that somebody who meets you on two platforms recognises the same business. What you are adapting is line breaks, which some platforms strip, emoji conventions, which differ sharply by audience, and where a link is allowed to live at all.
These four get written interchangeably and they answer different questions. A bio answers should I follow this, in a fraction of a second, for a stranger who arrived from one post. A professional headline answers what is this person, and it travels with your name into contexts where nothing else about you is visible, so it has to make sense with no surrounding page. An about section answers why should I believe this, and it can afford narrative, history and detail. A spoken pitch has different rhythm entirely and can respond to the person in front of you.
The common mistake is compressing an about section into a bio, which produces a dense paragraph of qualifications, or inflating a bio into an about section, which produces a page of slogans. Write the bio for the follow decision only. Everything explaining, justifying or evidencing belongs one click away, and the bio's job is to make that click worth taking rather than to pre empt it.
Read the bio as somebody who has never heard of you and has just seen one post. Ask three questions of it: do I know what this account is about, do I know whether it is for me, do I know what I would do next. If any answer is no, the fix is usually to remove a label rather than add a line, because the characters are almost always being spent on categories instead of facts.
Then check it where it actually appears. Look at it on a phone, where line breaks fall differently and long words push the link down. Check how it truncates in the smaller preview that shows next to a comment or in search results, since the first thirty or so characters are often all anyone sees. Read it aloud with the emoji named, which is roughly what a screen reader will do, and cut any that do not survive that. Finally, put a reminder in the calendar twice a year to confirm the link still resolves to the thing the bio promises, because the most common fault in an otherwise good bio is a destination that quietly changed.
Common questions about social media bio generator output, answered without the sales pitch.
150 characters. X allows 160 for the bio field, and other platforms vary, which is why writing the shortest version first saves rewriting for each one.
