LinkedIn comment generator

Comments are the cheapest visibility on LinkedIn: your name and headline in front of someone else's audience, attached to a thought. Paste the post you are replying to, add your own take if you have one, and get three comments that add something, sharpen something, or push back politely. Never 'Great post!'.

Fill in what you have. More context, better output.

Example run

Three comments on the same post

The visitor gave one sentence of their own experience, and it turns three generic replies into three versions of a real contribution.

What went in

The post you are replying to
Unpopular opinion: most founders should spend less time on their product and more time talking to the people who almost bought it. The lost deals know exactly what your product is missing, and they will tell you for free.
Your take or experience with the topic
We started doing loss interviews last quarter and two of them turned into closed deals six months later.

Comment 1 · From experience

Atta Ur Rehman Shah

We started loss interviews last quarter. Two of those lost deals came back and closed six months later, which was not the point of the exercise, but nobody complained.

Comment 2 · Adds a point

Atta Ur Rehman Shah

The underrated part: lost deals are more honest than churned customers. They have nothing to lose by telling you exactly where you fell short. Two of our roadmap items came straight from those calls.

Comment 3 · Asks back

Atta Ur Rehman Shah

Agree, and we have the receipts: two loss interviews from last quarter turned into closed deals since. Do you script those calls or keep them loose?

Why it matters

Comments reach people your posts cannot yet.

A sharp comment under the right post puts you in front of rooms you have not built an audience in. For B2B teams it is the cheapest distribution on the platform.

Beyond the demo

This page writes from a form. The product writes from you.

The generator above works with whatever fits in a few fields. Connect LinkedIn to Depost AI, the AI content team B2B founders and teams run on LinkedIn, and the same kind of draft starts from your analytics, your voice, and the buyers you are actually trying to reach.

Drafts that start from your analytics

The agents read your posting history first: the hooks that earned the click, the pillars your audience answers, the rhythm of what worked. The draft sounds like you because it learned from you, not from a form.

A reply ready for every person who matters

Build custom lists of the people you want to stay visible to. Their new posts arrive in one feed with a comment drafted in your voice under each. You edit or approve every one before it goes anywhere.

From draft to published, without the paste

Finished drafts go to the queue and publish through LinkedIn’s official API, with the first comment written alongside. Connection notes and follow-ups are drafted with the context already in place. Nothing goes out until you approve it.

Connect LinkedIn and you have a strategy, your pillars, and your first post ideas in about fifteen minutes.

The comment is a profile visit in disguise

Nobody follows you because of a comment, directly. What happens instead: your comment says something worth reading, a stranger hovers your name, your headline makes them curious, and the profile does the rest. Which means a comment is only as good as the chain it starts. A generic one breaks the chain at step one, because nobody hovers the name behind "So true!".

This is also why comments under the right posts beat comments under the biggest posts. Fifty replies deep under a celebrity post, you are wallpaper. Third comment on a post by someone your exact audience follows, you are visible, and you are visible to the right people. For a B2B team that is prospecting without the cold open: the comment section under an industry voice is where your buyers already spend their scroll. Choose the room before you polish the line.

Use the take field

The difference between the three comments this tool writes with and without your take is the difference between tailoring and guessing. Your take does not need to be polished; "we tried this and it half-worked" is plenty. The generator's job is the phrasing and the register, one agreeing and extending, one adding your evidence, one pushing back where you disagree. Yours is the thirty seconds of actually having a reaction.

Then edit before posting. Cut anything you would not say out loud, and post under the version that sounds most like you on a good day. The comment box caps at 1,250 characters, which these fit inside with room to spare.

Questions

Do comments actually help you grow on LinkedIn?
Yes, and for most people faster than posting. A sharp comment puts your name and headline in front of someone else's audience, in a context where you are visibly thinking rather than promoting. People check the profiles of commenters who added something. It is the lowest-cost way to be discovered by exactly the crowd that follows the people you want to reach.
What makes a LinkedIn comment worth leaving?
It adds one of three things: a specific experience ("we tried this, here is the number"), a sharpening of the point, or a respectful pushback. "Great post!" adds none of them, and neither does restating the post in different words. One to three sentences is the right size; a comment that becomes an essay should probably be your own post.
How does this comment generator work?
Paste the post you are replying to and, ideally, your own take on it. You get three comments, each taking a different tack. The take field is optional but it is where the quality comes from: with it, the generator is arranging your thought; without it, it is guessing at one.
Is it cheating to use AI for comments?
Using it to fake interest in posts you never read is a waste of everyone's time, including yours. Using it to say the thing you actually think, faster and more clearly, is editing. That is why the tool asks for your take, and why you should edit before posting: the comment goes out under your name, and your name is the whole point of commenting.
Is it free, and is my input stored?
Free, no account, with a daily cap so it stays available. The post and your take are sent once to generate the comments and are not stored.
How do I do this at scale without living in the feed?
The bottleneck is not writing comments; it is reliably seeing the right posts. In Depost AI you build custom lists of the people who matter to you, their new posts arrive in one feed, and a reply is drafted in your voice under each. You edit or approve each one, so the volume comes from the workflow while the words stay yours.
