Your LinkedIn headline shows up next to your name everywhere — search results, comments, connection requests — which makes it the single highest-leverage 220 characters on the platform. This generator writes headline-style variants focused on the language recruiters and clients actually search for, not vague titles like "passionate professional."
Free Mode — bios are written by a rule-based engine running in your browser, not a live AI API call. Here's exactly how that works.
No sign-up. No email. Bios generate locally.

LinkedIn's search and recommendation systems weight your headline heavily, and it's the only part of your profile visible in most contexts without a click. A headline built from your actual title plus the specific outcomes you deliver ("consulting for Series A startups" beats "business consultant") shows up in more relevant searches and reads better to a human skimming results.
The About section has far more room — up to 2,600 characters — and is where you can expand on the same core idea with context, but it should still open with your strongest line, since LinkedIn truncates About text after a few lines until someone clicks "see more."
These are real outputs from this page’s rule-based engine, first variant only, with the inputs shown so you can reproduce them. The engine keyword-matches your profession (consultant, writer and coach land in “freelancer”, marketing and SEO in “marketer”, founder and owner in “business”), builds a short draft in a tone, and cuts it only if it passes the limit. The limit is 220 characters, so on LinkedIn nothing below was cut.
Input: name “David Osei”, profession “freelance consultant”, interests “project management, process design”.
116 / 220 characters. A tidy draft that uses about half of the limit. “Helping clients who come back” is the generic part; a recruiter or prospect searching for a project manager will not find a keyword there, so replace it with a specialty.
Input: name “Grace Liu”, profession “marketing manager”, interests “b2b saas, demand gen”.
110 / 220 characters. “Marketing manager” matched the marketer group, so the value line is about measurable growth. “Helping growth that’s actually measurable” is clumsy, but the interests (“b2b saas · demand gen”) are the kind of searchable phrase that does the real work on LinkedIn.
Input: name “Omar Haddad”, profession “software developer”, interests “python, data pipelines”.
80 / 220 characters. Minimalist tone produces the shortest result, 80 of 220 characters. That leaves 140 characters free for the keywords and outcomes that headlines are built from.
Input: name “Sofia Reyes”, profession “startup founder”, interests “climate tech, early hiring”.
127 / 220 characters. The Luxury connector is a poor match for a climate-tech founder, and “a company built to last” says nothing about what the company does. The interests, “climate tech · early hiring”, are the useful part.
Almost nothing. Even a long input stays inside the limit:
Input: name “Christopher Papadopoulos-Lindqvist”, profession “freelance management consultant”, interests “enterprise transformation, change management programmes”, Luxury tone. The full draft is 193 characters against a limit of 220.
Kept 193 characters.
The real constraint on LinkedIn is different. A headline is displayed as a single line, so the four-line drafts the engine returns need their line breaks replaced with separators such as a vertical bar or a middle dot. Your name also appears right beside the headline, so the “Name —” start of each draft is wasted space: for the long example it is 37 characters you can win back. And in tight spaces such as comment threads and connection requests, a long headline is shown only in part, so put your title and strongest keyword first. Platform limits are compared in the bio character limits reference.
Strip the name, join the pieces with a separator, and swap the generic value line for a specific outcome or specialty. An illustrative rewrite of example 2, from the same inputs:
Hand-written illustration, not tool output: 74 / 220 characters.
It starts with a title people search for, names the segment, and ends with a specialty, in about a third of the available space. The longer LinkedIn About section examples show how to expand the same idea, and short professional bio examples covers other short formats.
The Bio Score (five checks of up to 20 points) gives the four first variants above 90, 82, 74 and 90 on the LinkedIn limit. Omar’s 74 comes from clarity (80 characters is under half of 220) and the lack of a closer under Minimalist tone, and neither of those is a problem on LinkedIn, where a short headline can be a good one. Treat the score as a structure check, not a quality grade. The tool shows an average across all seven platforms.
Read the finished headline as a recruiter would. Does it begin with a title or role people actually search for? Is there a specific keyword (a tool, a sector, a method) rather than a vague quality? Does it say what you deliver, not only what you are? Is it a single line without the generator’s line breaks? And does it agree with your About section and current job title? A headline that contradicts the rest of the profile reads as careless. Because the engine’s drafts use about half of the 220 characters, you have the room to add all of these without crowding the line.
220 characters. The About section has a separate, much larger limit of 2,600 characters.
Ideally both — a value statement alone can look vague to recruiters searching by title, so the strongest headlines combine a recognizable title with a specific outcome or specialty.
A little targeted keyword use (your real skills and title) helps you show up in recruiter search, but stuffing hurts readability and looks worse to an actual human reader — balance both.
