Your goal on LinkedIn

Verifying you're human…

Three headlines and an About section. Free, no signup, 2 runs a day. ~15-30s.

After your profile

A better profile only pays off when people visit it.

Your headline shows next to every comment you leave, so the fastest way to get profile visits is commenting on the posts your audience reads. Commentify's Comment Agent does that every day, in your voice.

How it works

A new headline and About in two minutes

  1. 01

    Say what you do and who for

    One or two sentences in plain words. 'Fractional CMO for early-stage B2B SaaS, I build their first marketing engine' is plenty.

  2. 02

    Add one result and your goal

    A result or credential if you have one, and whether you want clients, a job or an audience. The goal changes how the About section ends.

  3. 03

    Pick a headline

    You get three options with different angles, each under LinkedIn's 220-character limit.

  4. 04

    Fill in the blanks and paste

    Replace any [highlighted] placeholders, then paste the headline and About into your LinkedIn profile.

What good looks like

What your headline and About need to do

The headline

It shows under your name on your profile, in search results and next to every comment you leave. A job title alone tells people what you are, not why they should care. The headlines that work say who you help and what changes for them, in words a stranger would understand.

The About section

LinkedIn shows about three lines before "see more", so the opening has to earn the click: the problem you solve or a specific claim, never "I am a passionate...". After that, who you help, how, the proof, and one clear next step.

  • ✓Short paragraphs with blank lines between them.
  • ✓Specific results beat adjectives. "Took two startups to $1M ARR" beats "results-driven".
  • ✓End with what you want the reader to do: message you, book a call, follow.
  • ✓Keep it under 2,600 characters, LinkedIn's limit. 150 to 300 words is plenty.
FAQ

LinkedIn Summary Generator FAQ

Is this LinkedIn summary generator free?

+
Yes. No signup and no credit card. Each visitor gets two runs a day, which keeps bots from running up our AI bill.

Is the LinkedIn summary the same as the About section?

+
Yes. LinkedIn renamed the Summary to About a few years ago. It's the paragraph section near the top of your profile, and this tool writes it along with your headline.

How long can a LinkedIn headline and About section be?

+
The headline can be up to 220 characters and the About section up to 2,600. Every result shows its character count, and headlines over the limit are never suggested.

Why are there [bracketed] blanks in my About section?

+
The tool only uses what you typed. Where a strong profile needs a fact you didn't give (a number of clients, a result, years of experience), it leaves a placeholder like [number of clients] instead of making one up. Fill them in before you paste it into LinkedIn.

Which headline should I pick?

+
The one a stranger would understand in five seconds. Your headline appears next to every comment and post you make, so for most founders and consultants the "who you help" version works best. Use proof first if you have a strong number.

Can it write in my voice?

+
This free version works from the few lines you type. It writes in a confident, plain first person that you can adjust. Commentify's Post Agent is the version that learns your voice from your past LinkedIn posts.

Do you save what I type?

+
We keep your "what you do" text with the job record for 24 hours for abuse prevention and debugging, then it is deleted automatically. The generated headline and About are not saved on our side.
