One extension ยท every feed
Write the comment everyone remembers. On LinkedIn.On X.On Reddit.On YouTube.
Three drafts in your tone, streamed into a side panel on the post you're reading. Edit, refine, paste.

Comments drive reach.
Most people wing them.
A sharp comment on someone else's post gets seen by their audience, not yours. That's true on LinkedIn, X, Reddit, and YouTube alike. Commenteur Pro turns the blank-reply stare into a three-second decision, wherever you scroll.
Four networks, one panel
LinkedIn for reach, X for speed, Reddit for depth, YouTube for community. The same button, the same panel, comments written in each platform's native register. No tab switching, no re-pasting context.
Three drafts, streamed live
Every generation produces three distinct takes on the post, streamed word by word into the side panel. Pick the sharpest one instead of praying the single output lands.
Eleven tones, one voice dial
Professional for prospects, Witty for peers, Roast for the brave, Devil's Advocate when the hot take deserves pushback. Storyteller, Fact Checker, Hype Man, and more.
Replies that follow the thread
Replying to a comment, not a post? Commenteur Pro reads the parent post and the thread above, so your reply engages with what was actually said.
One-tap refinements
Shorter. Punchier. Add a question. More formal. Each chip rewrites your current draft, including your own edits, in a second pass.
Sees the chart in the post
Posts with images get comments that reference the visual, the thing 99% of commenters scroll past.
Nothing stored, ever
Post content is processed in real time and discarded. No logging, no training on your data, no comment history sitting on a server.
How it works
No new tab.
No prompt writing.
No context switch.
Everything happens inside the site you're already on, LinkedIn, X, Reddit, or YouTube. The feed stays open, the panel does the work, and the comment is yours before the post scrolls away.

Click the button under any post
A small Commenteur Pro button sits in every post's action bar, next to Like and Comment. One click and the side panel opens with the post already read. Right-click works too.

Watch three drafts stream in
Pick a tone and length once. Commenteur Pro remembers. Three distinct comments appear in about two seconds, written for that specific post.

Refine, then paste
Tap a chip to make it shorter or punchier, edit any word yourself, then hit Paste and it lands in the comment box on the page. You always press Post yourself.
We will never automate posting.
Commenteur Pro does one thing. It writes great comment drafts. It never runs your account. Every comment is reviewed by you, edited by you, and posted by you. You stay in the driving seat. We just make the writing fast.

Fair questions.
The ones everyone asks before installing a tool that writes in their name.
Which platforms does Commenteur Pro work on?
LinkedIn, X (Twitter), Reddit, and YouTube. The same side panel, button, and tones work on all four, and Commenteur Pro writes in each platform's native register. Polished for LinkedIn, punchy under 260 characters for X, substance-first for Reddit, casual for YouTube.
Will people know I used AI?
Not from reading it. Commenteur Pro bans the tells. No em dashes, no 'Great post!', no hashtag spam, one emoji max. You get three drafts to choose from and can edit every word before posting, so the final comment is yours.
Does this violate the platforms' terms of service?
Commenteur Pro is a writing assistant, like Grammarly. It never posts for you, never runs in the background, and never performs bulk actions on any platform. You read every comment and press Post yourself, every time.
What AI model powers this?
Claude by Anthropic, the same model family used by professional writing tools. Comments stream in live, in the same language as the post you're responding to.
Can I reply to comments too, not just posts?
Yes. Right-click any comment and Commenteur Pro reads the parent post plus the thread above it, then drafts a reply that engages with what was actually said.
What happens when I run out of comments?
Upgrade anytime or grab a one-off top-up pack. Top-up credits never expire and work on every plan, including Free.
Is my data safe?
Post content is processed in real time and immediately discarded. Nothing is stored, nothing is used for training, and nothing is sold. The extension only runs on linkedin.com, x.com, reddit.com, and youtube.com.
The next post you scroll past
was a chance to be seen.
Open any feed and leave one comment worth replying to. That's the whole pitch.
