Built for LinkedIn, not adapted from a generic tool
A LinkedIn comment reads nothing like a reply on X. It is longer, warmer and more professional, and the thread under a promotion post behaves nothing like the thread under a benchmark write-up. Four things make the difference.
It reads the post type first
A new role, a funding round, a benchmark write-up and a hiring post attract completely different comment sections. The generator classifies your post, then writes to that: congratulations stay short and warm on a career update, and a technical post gets implementation detail, tradeoffs and the occasional careful caveat.
LinkedIn comment culture, not generic AI
LinkedIn threads are supportive by default. Most people who stop to comment liked the post. Around three quarters of a generated set agrees, appreciates or builds on a point, and the doubt that does appear opens politely instead of leading with the objection.
Real length variety
LinkedIn comments run from two words to a paragraph. Every set has a counted floor of genuinely long comments, so you never get twenty one-liners, and short agreement still has to name what it is agreeing with.
Questions stay rare
The fastest way to spot a generated comment section is that everything ends in a question mark. Questions are capped at a quarter of the set, and zero on post types where asking would be rude, such as a career update or a company announcement.
What a generated LinkedIn 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.
Deleting steps is so underrated. Congrats to whoever pushed this through.
Agreed on the approval bloat. We have six and I am fairly sure two exist because someone got burned in 2019 and nobody has revisited it since.
Really useful to see the numbers. The part worth writing up is how you got approval to remove approvals. That is usually the hard bit, not the process design itself, and most teams stall exactly there.
Strong result. The only thing I would watch is what those four steps were quietly catching, because that tends to show up in week three rather than week one.
An illustration, not a real generation. Yours follow your post and your settings.
Who uses it
Marketing and social teams
The people already expected to show up under the company post. Everyone starts from a draft that sounds like a person instead of staring at an empty box.
Founders and operators
You wrote the post and now you have to carry the thread under it. See the likely reactions first and have your answers half written.
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 edit and post.
Nothing is posted to LinkedIn
There is no login to LinkedIn, no automation and no scheduling. The generator writes drafts, you read them, and a real person decides what to publish. LinkedIn's Professional Community Policies ask for authentic contributions and rule out artificially inflating engagement with your own content, so edit what you post and mean it. Our terms say plainly that what happens after a comment leaves this site is your responsibility.
Questions people ask
Is this LinkedIn comment generator free?+
Yes. Without an account you get 3 generations a day at up to 20 comments each. A free account raises that to 5 generations a day at up to 100 comments each. No card is needed.
Does it post the comments to LinkedIn for me?+
No. There is no connection to your LinkedIn account and nothing is ever published, scheduled or sent. The comments come back as text you can copy or download, and posting any of them is your decision.
Will the comments look AI generated?+
They are written to read as many different people: different lengths, seniorities, writing habits and opinions, with the AI tells and stock phrases explicitly ruled out. They are still drafts. Read them, edit the ones you like into your own words, and drop anything that does not sound like you.
Can I control the tone, audience or length?+
Yes. Just Generate infers everything from the post. Quick Tune sets audience, tone, length mix and technical depth. Advanced adds industry, seniority, skepticism, question frequency, emoji use, jargon, words to avoid and about thirty more settings.
Is using generated comments against LinkedIn's rules?+
LinkedIn's Professional Community Policies ask for authentic, original contributions and prohibit doing things to artificially increase engagement with your own content. A comment a real person edits, means and posts from their own account is a draft like any other. Coordinating accounts to prop up a post is what the policy rules out. You are responsible for what you publish.
Do you keep my post or the generated comments?+
No. Your post is sent to the model to generate the comments and is not retained afterwards or used for training. The comments are not saved either, so download them before you close the tab.
