How to Write a LinkedIn About Section Using ChatGPT

Staring at the blank About section on your LinkedIn profile can feel like one of the most stressful writing assignments ever. You have 2,600 characters to perfectly summarize your entire professional life, show off your personality, and attract the right kind of attention - all without sounding like a corporate robot. This article breaks down exactly how to use ChatGPT as your creative co-pilot to craft a compelling LinkedIn summary, from gathering your raw materials to refining the final draft.

Why Your LinkedIn "About" Section Is Your Most Important Piece of Social Media Real Estate

Before we get into the "how," let's quickly cover the "why." Many people treat their LinkedIn summary as an afterthought, pasting in a few generic lines from their resume. That’s a massive missed opportunity. Your "About" section is often the first thing a recruiter, potential client, or future collaborator reads after your headline.

Think of it as the ultimate elevator pitch. It’s your chance to:

• Tell Your Professional Story: Go beyond the bullet points of your job history and connect the dots. How did you get where you are? What drives you?
• Showcase Your Personality: Are you a data-driven analyst, a creative storyteller, or an empathetic leader? Your tone and phrasing communicate this faster than any job title.
• Optimize for Search: Your summary is packed with keywords that help people discover your profile when they search on LinkedIn for specific skills or expertise.
• Drive Action: It's the perfect place to tell people what you want them to do next, whether it’s connecting with you, checking out your portfolio, or scheduling a call.

But writing about ourselves is hard. We’re often too close to our own work to see the narrative clearly. That's where a tool like ChatGPT becomes incredibly useful - not to write it for you, but to help you build it block by block.

Step 1: Gather Your Raw Materials (The Pre-Prompting Prep)

ChatGPT is a powerful tool, but it can’t read your mind. Garbage in, garbage out. The better information you provide upfront, the better the result will be. Before writing a single prompt, take 15 minutes to gather the following information in a separate document. This is your "source material."

Your Raw Data:

• Job History &, Achievements: Don't just copy your resume. For your top 2-3 most relevant roles, write 3-5 bullet points about your specific accomplishments. Use metrics! Instead of "Managed social media," try "Grew Instagram following by 300% in 12 months by launching a new Reel strategy."
• Core Skills: List your top 5-10 hard and soft skills. Examples: Content Strategy, Public Speaking, SEO, Team Leadership, JavaScript, Client Relationship Management.
• Your "Why": In one or two sentences, describe what drives you professionally. What problems do you love solving? What impact do you want to make? Example: "I'm fascinated by how brands can build genuine communities through storytelling."
• Target Audience: Who are you trying to attract? Be specific. "Recruiters at tech startups," "Potential clients looking for freelance graphic design," or "Fellow marketers to network with."
• Desired Tone &, Voice: How do you want to sound? Pick a few words to guide ChatGPT. Examples: "professional but approachable," "energetic and witty," "authoritative and insightful," "creative and friendly."

Once you have this document ready, you're prepared to instruct ChatGPT effectively.

Step 2: Crafting Prompts to Build Your Summary Piece by Piece

Instead of just asking ChatGPT to "write a LinkedIn About section," we're going to use a series of more specific prompts. This approach gives you more control and produces a much better, more authentic result. Here’s a step-by-step process with prompts you can copy and paste.

Prompt 1: Create the Foundational Outline

First, we’ll ask the AI to act as a specialist and structure your raw data into a narrative. This helps organize your story before any prose is written.

Act as an expert brand strategist and LinkedIn profile writer. Your task is to take the information I provide and organize it into a compelling narrative structure for a LinkedIn 'About' section. Do not write the full summary yet - just create an outline.

The structure should include:
1. **A strong opening hook** to grab attention.
2. **A "Connecting the Dots"** section to explain my professional journey and my 'why'.
3. **A "Core Expertise"** section highlighting my key skills with quantifiable achievements.
4. **A concluding section that outlines who I help** and sets up a call to action.

Here is my source material:
[Paste all the information you gathered in Step 1 here.]


ChatGPT will spit back a skeletal structure. You can review it, see if the story flows, and make adjustments. Maybe you want to reorder some sections or see if a different angle works better. It's much easier to edit an outline than a full block of text.

Prompt 2: Generate the First Drafts

Once you’re happy with the outline, it’s time to generate the copy. We'll ask for a few different versions to see what style resonates most with you.

Excellent. Now, using that outline, write three different LinkedIn 'About' section drafts for me. Keep each version under 2,600 characters.

* **Version 1:** Write it as a professional, first-person narrative.
* **Version 2:** Write it using a more scannable format with clear subheadings, and use bullet points or emojis to highlight achievements.
* **Version 3:** Write it as a more formal, third-person bio.


You’ll get three distinct options. Maybe you'll love Version 1 right away, or perhaps you'll want to combine the storytelling of Version 1 with the scannable format of Version 2. This step is about generating possibilities, not finding the perfect final product.

Prompt 3: Refine a Version with Tone and Voice Adjustments

Pick the draft you like most and now let’s start refining it. The first drafts from ChatGPT can sometimes feel a bit generic. This is where we inject more personality.

Let's focus on refining Version 1. The current tone is a bit too formal. Rewrite it to be more [conversational and approachable / energetic and witty / insert your desired tone here].

Instead of just stating facts, focus more on storytelling. Frame my experience around the challenges I solved for businesses. Make it sound less like a resume and more like I am introducing myself to a new colleague.


This iterative process is the most valuable part of using AI. You can go back and forth, asking it to make your writing "bolder," "more concise," or "funnier" until it starts to sound like you.

Prompt 4: Weave in Keywords for LinkedIn SEO

Your "About" section is prime real estate for keywords that help you show up in searches. But you want to add them naturally, not just stuff them in like a 2005-era blog post.

This is much better. Now, review the text and strategically incorporate the following keywords:

- [Keyword 1]
- [Keyword 2]
- [Keyword 3]
- [Keyword 4]
- [Keyword 5]

Weave them into the existing sentences naturally. Don't add them as a list at the end. The goal is for the summary to remain readable and human-centric while still being keyword-rich for LinkedIn search.


This ensures your profile gets discovered by the right people without sacrificing the quality of your personal narrative.

Prompt 5: Craft a Powerful Call-to-Action (CTA)

A great summary always tells the reader what to do next. Don't leave them guessing.

Finally, let's create a strong call-to-action (CTA) for the end of the summary. Generate three distinct CTA options for me:

1. One focused on connecting and networking.
2. One encouraging people to view my portfolio or work.
3. One inviting potential clients to get in touch.

Suggest some special characters (like arrows ▼) or light-touch emojis to make the CTA section stand out.


Step 3: The Human Touch - Your Final Editing Pass

You now have a 95% complete LinkedIn "About" section that’s structured well, reflects your tone, is optimized for search, and has a clear CTA. But the final 5% is all you. AI is a tool, not a replacement for your own voice and experience. Here's your final checklist:

• Read It Aloud: Does it actually sound like something you would say? Tweak any phrases that feel clunky or inauthentic.
• Fact-Check Everything: AI can sometimes "hallucinate" or misinterpret data. Make sure all your metrics, job titles, and accomplishments are 100% accurate.
• Add a Personal Detail: Inject a small, unique personal detail that ChatGPT couldn't possibly know. A line about your love for rock climbing, minimalist design, or baking sourdough can make you instantly more memorable and relatable.
• Format for Readability: Break up long paragraphs. Use bullet points or numbered lists if it makes sense. People scan on social media, so create lots of white space to make your summary easy on the eyes.

Final Thoughts

Writing your LinkedIn "About" section doesn’t have to be a daunting task. By pairing your expertise with the generative power of ChatGPT, you can move from a blank page to a polished, professional summary that truly represents your brand. The key is to see the AI not as an author, but as a strategic assistant that helps you brainstorm, structure, and refine your own story.

Of course, a great profile is just the beginning. To truly stand out, you need to share valuable content consistently. At Postbase, we streamlined a visual calendar and scheduling tool so you can plan and publish across all your important channels, including LinkedIn, without the headache. Ultimately, our goal is to help you get your brilliant profile noticed by making it simple to manage the actual social media activity that drives results.
