LinkedIn Summary Generator — Free AI Tool

Answer 5 quick questions and get a ready-to-paste About section in three proven styles: value-first, story-led, and credibility-first. Free, no signup.

Be specific. “B2B SaaS founders” beats “businesses”.

Numbers beat adjectives. “Grew pipeline 3x” beats “results-driven”.

The anatomy of a great LinkedIn summary

Every high-converting About section does four jobs, in this order:

1. Hook: who you help & the outcome

Only ~3 lines show before “see more”. Open with “I help X do Y” so even people who never expand it get your positioning.

2. How: your approach

One or two paragraphs on how you deliver that outcome - your method, your beliefs, what you do differently.

3. Proof: results and receipts

Numbers, named companies, exits, rankings, press. Proof turns your claim into a fact the reader can trust.

4. CTA: what to do next

Connect, DM, book a call, subscribe. Give the reader one clear next step - profiles without a CTA leak warm leads.

What makes a great LinkedIn summary?

Nail the first 3 lines

LinkedIn truncates your summary after roughly 3 lines with a "see more" link. Put your "I help X do Y" statement in the first sentence so the value shows before the fold.

Open with who you help and the outcome

The same formula that wins headlines wins summaries: "I help X do Y." State it plainly in line one, then spend the rest of the section proving it.

Write in first person

Third-person summaries ("Cassy is a results-driven leader...") read like a press release. First person builds a connection - it's your profile, talk like yourself.

Show proof, not adjectives

"Results-driven" and "passionate" are claims. "Grew pipeline 3x in 12 months" is proof. Swap every adjective you can for a number, a name, or a story.

End with a call to action

Tell people what to do next: connect, DM, book a call, subscribe. A summary without a CTA is a story without an ending.

Use short paragraphs and white space

Nobody reads a wall of text on a profile. Keep paragraphs to 1-3 lines, use line breaks generously, and make it scannable on mobile.

Frequently Asked Questions

The LinkedIn About section (summary) has a maximum of 2,600 characters, including spaces and line breaks. Only the first ~3 lines show before the "see more" link, so front-load your most important message.
Lead with who you help and what you help them achieve ("I help X do Y"), then back it up: how you do it, proof that it works (results, numbers, named wins), and a call to action telling people what to do next. Write in first person and keep paragraphs short.
Aim for 3-6 short paragraphs, roughly 600-1,500 characters. That's long enough to tell a story and show proof, short enough that people actually read it. The 2,600-character limit is a ceiling, not a target.
First person, almost always. Your profile is a conversation with the person reading it - third person creates distance and reads like a corporate bio. The only common exception is a page managed on behalf of a public figure.
Your headline is the one-liner that shows everywhere - search results, comments, connection requests (220 characters). Your summary is the About section on your profile where you get 2,600 characters to expand on it. The best profiles use the same core positioning in both: state "I help X do Y" in the headline, then prove it in the summary.
Yes. LinkedIn search indexes your About section, so naturally including the terms your audience searches for (your role, skills, and industry) improves discoverability. Write for humans first, then make sure the obvious keywords are present.
