“Write me a good LinkedIn bio.”
Nothing wrong with the sentence. Nothing in it either. No role, no achievement, no reason anyone reading it would remember you by the time they scroll past. A prompt this open doesn't get you a bad bio, it gets you the most average one possible.
The usual fix, and why it rarely happens
The advice for this is everywhere, and most of it wants something from you first. A free PDF cheat sheet behind an email address, forgotten in a folder by the time you actually need it. A course that promises to teach you prompt engineering in exchange for a few hundred euros and a few hours you don't have, most of which just walks you through what you'd have figured out anyway by doing it. It takes time to learn and more time to apply correctly every single time you sit down to write something, and a LinkedIn bio doesn't wait for you to finish the course.
How CORDON helps
CORDON skips the framework entirely. Six letters, one prompt that works. No framework terminology, no deciding which technique applies, just answering what's actually true about the situation, only the fields that genuinely do. Just bookmark it, and it's there the next time you need it, no course to remember, no cheat sheet to dig up. For a LinkedIn bio, that's barely more than a minute of typing:
What's the situation?
“I'm a solo founder running a small SaaS product, no team, no funding.”
What do you want the AI to do?
“Write a LinkedIn About section.”
Who should the AI be?
“Act as a personal branding expert.”
Why do you need this?
“I want to look credible to potential customers browsing my profile.”
How should the answer look?
“Around 150 words, first person.”
What should it avoid or respect?
“Professional but not corporate, no buzzwords.”
Six questions that you answer about your situation.
The prompt it generates
From those six answers, CORDON builds the custom prompt in seconds:
“You are a personal branding expert who specializes in helping founders craft authentic, compelling professional narratives. Write a LinkedIn About section for a solo founder running a small SaaS product with no team and no outside funding.
The section should be written in first person and run approximately 150 words. Its primary job is to build credibility with potential customers who land on the profile, so it should feel like someone worth trusting and doing business with, not someone pitching for investment or clout.
The tone must be professional but human and direct, the kind of voice that makes a reader feel like they're hearing from a real person. Avoid all buzzwords, vague value-language, and corporate filler phrases. No “passionate about disrupting,” no “leveraging synergies,” no hollow superlatives.
Structure it naturally: open with who this person is and what they build, move into why they built it and what problem it solves, and close with a clear signal of who should reach out and why.”
Ready to paste into ChatGPT, Claude, Gemini, or whichever model you prefer.
What the six answers turned into
Compare that custom prompt to the six raw input above it. Nothing in it is information you didn't already type in. What changed is that it's no longer six disconnected answers, it's aimed: the tone gets a negative example (what “not corporate” actually rules out), the structure gets an order to follow, and the credibility goal shapes the whole brief instead of sitting in its own field, ignored by the rest.
Closing
That's the actual product. Not five handy PDFs to remember, not an expensive course to eventually get around to, six questions and a custom prompt. Try CORDON with your own situation, the difference shows up before you've had time to overthink it.
