Free tool vs. Post Agent

Want posts that sound like you? The Post Agent learns your voice.

This generator writes from your topic alone, so it leaves blanks for your details. Commentify's Post Agent reads your past LinkedIn posts first, then drafts your week in your voice, adds an image to every post and schedules them.

How it works

From topic to a post you can publish in two minutes

  1. 01

    Type your topic

    An idea, a lesson or an opinion. Specific beats broad: 'What raising our prices taught me' gives a better post than 'pricing'.

  2. 02

    Wait about 30 seconds

    We write three posts at once: a story, a contrarian take and a how-to list. You'll see each one start as it is written.

  3. 03

    Pick an angle and fill in the blanks

    Choose the post that fits what you want to say. Replace the [highlighted] placeholders with your real details.

  4. 04

    Format, preview and post

    Copy it straight into LinkedIn, or send it to the text formatter to bold a phrase and check where "...more" cuts it.

The three angles

One topic, three ways to tell it

The same idea lands differently depending on how you frame it, so the generator writes it three ways and lets you choose.

Story

A first-person moment: what happened, what you did, what it taught you. The lesson comes at the end, which is what keeps people reading. Best when you have a real experience behind the topic.

Contrarian take

States a common belief about your topic, then says why it is wrong or incomplete. These start the most conversations, so use one when you actually disagree with the usual advice.

How-to list

Three to seven numbered steps someone could act on today. The easiest format to save and share, and a safe pick when you want to be useful rather than provocative.

What it gets right

Built for how LinkedIn shows posts

  • ✓The first line is the hook and stays under 120 characters, so it shows in full before "...more" on a phone.
  • ✓Short paragraphs of one to three lines with blank lines between them. That's how posts read on mobile.
  • ✓120 to 250 words: enough to say something, short enough to finish.
  • ✓Plain text only. LinkedIn doesn't render markdown, so there are no stray asterisks or pound signs.
  • ✓No em dashes and no stock AI phrases. Those are the first things readers notice.

It also refuses to make things up. Where a post needs a personal fact, you get a [placeholder] instead of an invented win.

FAQ

Free LinkedIn Post Generator FAQ

Is this LinkedIn post generator free?

+
Yes. No signup and no credit card. Each visitor gets two runs a day, three posts per run. The limit keeps bots from running up our AI bill and keeps the tool for trying ideas. If you want posts every week, that's what the Post Agent is for.

How does it work?

+
You type a topic, an idea or an opinion. We send it to an AI model with a prompt written for LinkedIn: a hook that fits before "...more", short paragraphs, a real question at the end, and a list of AI phrases it may not use. It returns three posts on different angles. You pick one, fill in your details and post it.

Why are there [bracketed] blanks in the posts?

+
Because the tool doesn't know you. Rather than invent a result, a client or a number you never had, it leaves a placeholder like [your result] for you to fill in. Posting a made-up story is worse than not posting.

Will the posts sound like AI?

+
Less than most. The prompt bans the usual tells (em dashes, "delve", "game-changer", "It's not X, it's Y", tidy groups of three) and we strip dashes from the output. Still, read it out loud and change anything you wouldn't say. A draft you edit beats a draft you paste.

Can it write in my voice?

+
Not this free version. It has only your topic to go on. Commentify's Post Agent reads your past LinkedIn posts first, so its drafts sound like you, and it adds an image to every post.

How long should a LinkedIn post be?

+
Most strong text posts land between 120 and 250 words, which is what the generator aims for. LinkedIn allows up to 3,000 characters, but on a phone a long post has to earn every scroll. What matters most is the first line, because LinkedIn shows roughly the first 140 characters on mobile before cutting to "...more".

Do you save my topic or the posts?

+
We keep the topic with the job record for 24 hours for abuse prevention and debugging, then it is deleted automatically. The generated posts are not saved on our side.
