This is such a crisp take. The part about shipping imperfect V1s and learning in public really landed — saving this for the team sync.

Curious — how are you measuring comment quality vs engagement rate? We’ve been debating the same tradeoff this quarter.

Agree with your point on authenticity. Generic praise kills trust. Comments that add one concrete insight outperform every time.

Bookmarking this. The difference between “nice post” and a real contribution is night and day for inbound leads.

This matches what we’re seeing — short, specific comments get replies. Long essays get ignored.

From AI Comment

Love this. The PR → AI review → GitHub comment loop is so clean — curiosity over perfect plans is exactly how we unblocked our last release too.

How it works

Four quiet steps.
Better comments.

commentbro doesn’t change how you use LinkedIn — it just removes the blank comment box.

01

Install the extension

Add commentbro from the Chrome Web Store. It sits in your browser quietly — no setup wizards, no dashboard to configure first.

Chrome Web Store

Add to Chrome
02

Scroll LinkedIn as usual

Open your feed. On every post you’ll see a blue AI Comment button next to Like and Reply — right where you already engage.

On the post

LikeCommentAI CommentRepost

No new tabs. No copy-paste.

03

Tap AI Comment

We draft a short, specific reply from the post itself — curious, useful, and human. Not a template. Not “Great post!”

Draft ready

“Love this framing — shipping in public beats waiting for a perfect plan every time.”

Usually under five seconds.

04

Edit if you want. Then post.

Tweak the tone, shorten it, or leave it as-is. Nothing goes live until you hit post. You’re always in control.

Ready to post

Edit tone, length, or keep the draft. You decide what goes live.

Your voice. Your profile.

That’s it. Install once, then comment without leaving the feed.

FAQ

Common questions

Quick answers about how commentbro works on LinkedIn.

Does commentbro post comments for me?

No. You always review the draft first. Nothing goes live until you hit post on LinkedIn.

Will comments sound like a bot?

Drafts are written to be specific to the post — curious, useful, and natural. You can re-generate or edit before posting.

Can I comment on image or video posts?

Yes, on Vision (image) and Media Pro / Unlimited (image + video) plans. Text-only plans still work on all posts with a text-based fallback.

Where does the AI Comment button appear?

Right on the LinkedIn post — next to Like and Comment in the action bar. No new tabs or copy-paste.

Testimonials

Loved by LinkedIn professionals

Founders, marketers, and creators use commentbro to comment faster — without sounding like a bot.

I used to skip commenting because I'd stare at a blank box for five minutes. One tap on AI Comment, a quick tweak, and I'm done — my reply rate on founder posts doubled in a month.

Finally something that doesn't sound like generic AI. The drafts reference the actual post — not just 'Great insight!' — and people actually reply back. Saved me hours every week.
