LinkedIn Comment Generator — 6 reply styles, instantly.

Paste any LinkedIn post URL. We read the post and draft 6 ready-to-paste comments — one per style — so you can pick the angle that fits.

Powered by Commentify

We'll read the post and draft 6 different comment styles you can copy. Free, no signup. ~30-60s.

How it works

From post URL to posted comment in under a minute

  1. 01

    Copy a LinkedIn post URL

    Open the LinkedIn post you want to comment on, hit the three-dot menu, and choose 'Copy link to post'. Or just copy the URL from your browser bar.

  2. 02

    Paste it in the form above

    Drop the URL in the input field and hit 'Generate 6 comments'. We read the post and start drafting.

  3. 03

    Pick the style that fits

    You'll get six comments — Insightful, Personal Story, Contrarian, Data-backed, Curious Question, Witty. Pick the one that matches your goal.

  4. 04

    Edit, then post

    Tweak it so it sounds like you. The best comments are AI drafts plus a sentence of your own voice. Then paste it into LinkedIn.

The 6 styles

Every post has multiple smart angles. We give you all of them.

A great LinkedIn comment is rarely polite agreement. The comments that get attention either add to the idea, push back on it, or open a real conversation. Here's how each style works:

Insightful Add-on

Builds on the author's point with a complementary insight, framework, or observation they didn't mention. Best for credibility — it positions you as someone who thinks about this stuff all the time.

Personal Story

A short, plausible-sounding anecdote that connects to the post's theme. Best for pattern-matching — your network sees you as the go-to person for this kind of work.

Contrarian Take

Respectfully pushes back on a specific claim. Best for visibility — contrarian comments rack up replies, and replies rack up reach.

Data-Backed

Adds a relevant statistic or concrete data point that supports or qualifies the argument. Best for authority.

Curious Question

Asks a specific follow-up the author would actually want to answer. Best for opening a DM — questions trigger replies, and replies are how DMs start.

Witty One-Liner

A short, dry, observational one-liner. Best for memorability — the witty commenters are the ones people remember 3 weeks later when they're ready to buy.

Why this exists

Comments outperform posts. Most people don't know that.

The dirty secret of LinkedIn growth in 2026 is that thoughtful comments on other people's posts drive more profile views, DMs and inbound than your own posts. They tap into reach you don't own, in front of audiences you haven't earned yet.

The hard part is that good comments take time. You have to read the post, find a real angle, draft something specific, and avoid sounding generic. Most people give up and just post "Great insight!" — which is statistically worse than not commenting at all.

This tool removes the friction. You get 6 specific angles in 30 seconds. You pick the one that's actually you and post it. Use it five times a day on the right posts and you'll see the difference within a week.

  • ✓Comments earn 4–7x more profile views than equivalent original posts (LinkedIn 2025 internal data, multiple sources).
  • ✓The first 5 comments on a post get disproportionate distribution — being early matters as much as being smart.
  • ✓Comments under thoughtful posts (1k+ likes) are seen by 10–100x your own followers.
FAQ

Free LinkedIn Comment Generator FAQ

Is this LinkedIn comment generator really free?

+
Yes. There's no signup, no credit card. We rate-limit to a few generations per IP per day so we don't get blown up by bots. If you need to do this at scale or on autopilot across the posts your buyers write every day, that's what the paid Commentify product is for.

How does it work?

+
You paste a public LinkedIn post URL. We read the post text and the author info, then ask GPT to draft 6 different comment styles — each calibrated for a different goal (insight, storytelling, contrarian take, data-backed, curious question, or witty observation). You pick the one that sounds like you and edit it to taste.

What kind of LinkedIn URLs are supported?

+
Any public LinkedIn post URL: posts/foo_..., feed/update/urn:li:activity:..., or pulse articles. Private posts and posts inside a closed group won't work — we can only see what a logged-out browser would see.

Will the comments sound like AI?

+
We deliberately tune the prompts away from generic 'Great post! Thanks for sharing' patterns. Each archetype has a specific job (push back, add data, share an anecdote, etc.) so the variants don't read like 6 versions of the same comment. That said — please edit them. The best comments are 80% the AI's draft and 20% your own voice.

Why 6 styles instead of just one?

+
Because every post has multiple smart angles, and the best comment depends on what you want. A 'curious question' is great for opening a DM thread. A 'contrarian take' is great for visibility. A 'data-backed' add-on is great for credibility. We give you all 6 so you can pick the one that fits your goal.

Will this get my LinkedIn account banned?

+
No. This tool only generates comment text — you copy and paste it manually. Nothing posts on your behalf. The full Commentify product handles posting safely with rate-limited automation, but this free tool is purely a writing assistant.

How is this different from ChatGPT?

+
ChatGPT can write comments, but you have to paste in the post text yourself, write the prompt, and remember which styles you've tried. This tool reads the post for you and gives you 6 deliberately-different angles in one click. It's a 30-second workflow vs a 5-minute one.
