"Most founders I know are obsessed with product. The ones who win are obsessed with distribution. You can have the best product in the world and still lose to a worse one with better reach."

SimplyComment

This hits. I've seen it play out firsthand — we had a stronger product than our main competitor for 18 months but they were everywhere and we weren't. Distribution isn't a feature you can ship later, it has to be baked in from day one.

Open any LinkedIn post

Click the SimplyComment icon, paste the post you want to comment on, and choose your mode — Polish Draft or Help Me Ideate.

Get your comment

SimplyComment generates a comment in your voice in seconds. Copy it, tweak it if you want, and post. Done.

Two modes

Start from scratch
or polish what you have.

Polish Draft

Have something in mind but can't quite phrase it? Write a rough draft, pick a direction — agree, disagree, ask a question, share experience — and SimplyComment refines it into a polished comment in your voice.

Help Me Ideate

No idea where to start? Paste the post, pick your angle, and let SimplyComment generate a comment from scratch — grounded in your voice profile so it still sounds like you, not like a robot.

FAQ

Common questions.

That's exactly what we designed against. SimplyComment builds a voice profile from your own writing, so generated comments reflect your vocabulary, sentence structure, and tone. The more writing samples you give it, the more authentic the output. You should still review before posting — but they won't read like generic AI.

Install the extension, then go to Settings and fill in your name, industry, and LinkedIn URL. Paste at least one post and one comment you've written — this trains your voice profile. That's it. The whole setup takes about 2 minutes.
Yes. You paste the post text into the SimplyComment popup, so it works on any LinkedIn post regardless of format.
SimplyComment is a writing assistant — it helps you write better comments, just like using Grammarly or any other writing tool. You review and post the comment yourself. It does not automate any LinkedIn actions or interact with LinkedIn's API.
