Writing good comments on LinkedIn

Comments on LinkedIn are read by your professional network. Keep them specific, add a thought of your own, and break longer comments into short paragraphs so they’re easy to scan.

Generated comments are a starting point: add one specific detail from the post (a name, a number, what you liked) before you publish. Copy-paste comments at scale are easy for platforms to detect and can be treated as spam.

How the generator builds a comment

Each comment combines an opener, a body and a closer written for LinkedIn in a professional voice. Topic details — like review or research — are chosen once per comment so every part talks about the same thing. Parts are separated into short paragraphs, the way comments read best on LinkedIn.

Frequently asked questions

How do I write a professional LinkedIn comment on a tech review post?
Start with a short reaction, add one sentence about what stands out, and close with a forward-looking line. For example: “Congratulations on the deep dive! It's clear how much attention to detail went into this, and it shows. Wishing you every success with your long-term verdict.”
Can I generate more than one comment?
Yes. Click “Re-roll” for a fresh comment as many times as you like — recent results are never repeated back to back.
What does “Make it spicier” do?
It turns the tone up a level (Professional → Hype → Sarcastic), and at the top level adds extra emoji.
Is it OK to post AI-style generated comments on LinkedIn?
Use them as a draft. Personalising each comment keeps it authentic and avoids being flagged as spam by platform filters.
Is the comment generator free?
Yes — it runs entirely in your browser with no sign-up, no limits and no data sent to a server.
