Comment on LinkedIn in your own voice — not the AI's.

Bring your own AI key. Co-Pilot reads the post, drafts a one-line comment that sounds like you, and you copy-paste. Drafts only — never posts on your behalf.

53 seconds of how it works.

From clicking a LinkedIn post to a thoughtful comment in your voice — start to finish.

The hidden growth lever

Commenting beats posting. Especially early.

Only 3% of LinkedIn's 1.3 billion members post weekly. Almost nobody comments well. That's the gap — and it's where personal brands actually get built.

Posting to zero followers is a store on a street with no foot traffic.

Commenting on a 50,000-impression post is a pop-up stand on the busiest street in town.

Strategic commenting per day = the lever

Three comment types that actually work.

In the first 90 days, comments matter more than your own posts. These three formats compound.

01 / NEW ANGLE

Add what the post missed

Bring a perspective the original author didn't cover. The author engages, their audience notices, the algorithm rewards depth.

02 / RESPECTFUL PUSHBACK

Disagree with a real reason

Push back on the take with a specific counter-point from your own experience. Disagreement that has a "why" generates the most engagement velocity.

03 / QUICK STORY

Connect with your experience

Link the post to a 2-line story from your own work. Concrete beats abstract. Story beats statistics. Yours beats anyone else's.

"Great post!" — the algorithm reads this as fake engagement. The author skims past it. The audience doesn't see it. Skip the empty agreement entirely.

The hard part isn't knowing this. It's showing up daily, with a real point of view, in your own voice. That's what Co-Pilot makes effortless.

But AI-written comments are obvious. They open with "Great post!" They use words you'd never use. They sound like a press release. So you stop using AI — and end up not commenting at all.

How it works

Three steps. Sixty seconds to set up.

1

Set your voice (60 seconds)

Pick your industry, tone, and length. Six tone presets — Professional, Casual, Witty, Contrarian, Supportive, Analytical. Six languages including Hindi and Hinglish. Optional: capture your real voice from your LinkedIn profile.

2

Click on a LinkedIn post

Open the side panel, click Comment on visible post. Co-Pilot reads the post and drafts a comment in your voice — short, opinionated, no "great post" nonsense. Or use Find fresh posts in my topics to surface five timely posts worth engaging with.

Edit, copy, paste

Tweak the draft inline if you want. Click Copy. Paste into LinkedIn yourself. Co-Pilot never posts on your behalf — drafts only. Compliant with LinkedIn's terms, and you stay in control of every word.

Common questions

Frequently asked.

Does this auto-post comments?

No. Co-Pilot drafts comments only. You review, copy, and paste them into LinkedIn yourself, every time. This is by design — it keeps you compliant with LinkedIn's terms and in control of every word that goes on your profile.

Do you store my LinkedIn data anywhere?

No. We don't have a server. Your API key, voice profile, and settings are stored only in your browser via chrome.storage.local. Post text is sent only to your chosen AI provider at the moment a comment is being drafted, using your API key.

What does the Gemini API cost?

For most users, nothing. Google offers a generous free tier at aistudio.google.com/apikey that covers normal use comfortably. If you exceed the free tier, you pay Google directly — never us.

Will this get me in trouble with LinkedIn?

No. Because Co-Pilot only drafts comments and you copy-paste them yourself, LinkedIn sees normal manual activity. We don't automate posting, scraping, or any action that violates LinkedIn's user agreement.

Can I switch from Gemini to Claude or OpenAI?

Yes. In Settings, pick any of the four supported providers — Google Gemini, OpenAI, Anthropic Claude, or OpenRouter (Llama, Mistral, DeepSeek, Qwen, and more). Your keys for each provider stay saved, so you can switch back any time.

Is there a Firefox or Safari version?

Chrome only for now. Microsoft Edge works since it's Chromium-based. Firefox and Safari support are on the roadmap if there's demand.

Why is the Pro tier coming "later"?

Because building paid features before knowing if anyone wants the product is wasted work. Phase 1 is free, broad, and meant to validate demand. If the product proves itself, we add a Pro tier in Phase 2. Early users grandfather in.
