A comment generator for LinkedIn and X posts.
Paste a post and CommentOnMyPost writes the comment section it would probably attract: the busy reply, the skeptical one, the person who wants the numbers, the person who just says nice work. They read as if different real people wrote them, and you copy the ones you want.
Nothing is ever posted. There is no connection to your LinkedIn or X account. The comments come back as text for you to read, copy or download.
Three steps
Paste the post
Your draft, caption or transcript goes in as plain text. Pick LinkedIn or X so the tone matches where it will live.
Set the room
Choose how many comments you want. Quick Tune sets audience, tone and length mix. Advanced adds industry, seniority, objections and more.
Copy what you want
You get a set of distinct, human-like comments in one pass. Copy one, copy them all, or download as CSV or TXT. Posting them anywhere is your call, not ours.
What a generated thread looks like
One post in, a scattered comment section out. Different lengths, different temperaments, no wall of "Great post!"
We cut our onboarding from 14 days to 3. No new headcount. Just deleted four approval steps nobody could justify.
Three days sounds great until something goes wrong in week two. What did you put in place to catch the things those approvals were meant to catch?
Which four? We have six and I am fairly sure two exist because someone got burned in 2019 and nobody has revisited it since.
Deleting steps is so underrated. Congrats to whoever pushed this through.
The part worth writing up is how you got approval to remove approvals. That is usually the hard bit, not the process design.
An illustration, not a real generation. Yours follow your post, your platform and your settings.
Who it is for
Anyone who has to fill the comment section under their own post, and would rather start from a draft than a blank box.
Marketing and social teams
The people who are already expected to show up in the comments under the company post. Instead of everyone staring at an empty box, each person starts from a draft that sounds like a person, edits it into their own words and posts it themselves.
Founders and operators
You write the post, then you have to carry the discussion under it. Generate the likely reactions, see which ones you can answer well, and have your replies half written before anyone asks.
Agencies and freelancers
Draft the comment angles for a client's post in one pass, then hand them over for the client's own people to review, edit and post from their own accounts.
What it will not do
It never posts anything
There is no connection to your LinkedIn or X account. Nothing is published, scheduled or sent. You copy what you want and that is the end of it.
It is not a bot network
These comments are written for you to read, not to be sprayed onto other people's posts from fake accounts. That is spam, and this tool is not built for it.
It does not invent facts about you
Comments react to what your post actually says. No fabricated metrics, no made up case studies, no quotes you never gave.
It does not keep your post
Your text is sent to the model to generate the comments and is not retained for training. What you paste stays yours.
Why it is useful
Conversation is what earns reach
A post with a real discussion under it travels further than one with a row of "Great post!" one-liners. Comments are engagement in their own right, and authentic, varied ones keep the discussion going, which is what feeds impressions and reach.
Robotic comments cost you reach
Generic AI filler reads as spam to humans and to the platforms. LinkedIn asks for original, relevant content and reduces the visibility of what breaks its policies. X treats bulk, duplicative and irrelevant replies as content spam. Sounding human is not a nice-to-have.
Hear the objections first
The skeptical reply you would have got in public is much cheaper in private. Rewrite the line that caused it before you publish, and draft your answer to the rest.
Find out which angle lands
Run the same post as a story and as a data point. The reactions tell you which framing people actually pick up, and which one your team should get behind.
Use them the way the platforms allow
A generated comment is a draft, not a finished post. Read it, edit it into your own words, and post it yourself from your own account. Two rules are worth knowing before your team starts.
Its Professional Community Policies ask you to create original, relevant content, to respond authentically, and not to do things that artificially increase engagement with your own content. Drafting a comment someone then edits and means is fine. Agreeing in advance to prop up each other's posts is what it rules out.
Read LinkedIn's policiesX
Its Authenticity policy prohibits inauthentic accounts, engagement spam, and posting content in a bulk, duplicative or irrelevant way. One considered reply from a real account is fine. Twenty near-identical ones pasted from a batch are the thing it is written against.
Read X's policyPlatform rules change and only the platforms enforce them, so check the current version before you build a habit around it. You are responsible for what you post, and our terms say so plainly: we cannot take responsibility for an account being restricted or blocked over comments you chose to publish.
What it costs
Nothing. Without an account you get 3 generations a day at up to 20 comments each. Signing in is free and raises that to 5 generations a day at up to 100 comments each. A generation counts as one whether it writes 1 comment or 100, and the count resets at midnight UTC.
