Used as light context so the comment sounds credible, not anonymous.
3 comment variants
each under 60 words
Fill in the form and click Generate. Your output appears here.
How to use the result
- Pick the variant closest to a real reaction you had. Edit one phrase so it sounds like you, not the tool.
- Add one specific detail: a number, a name, a memory. Comments without specifics read as filler.
- Don't open with "Great post!" Always cut that.
- Post in the first 2 hours after publication for the best reach lift.
- For comments in your voice, install the Chrome extension.
Why 60 words?
Comments over ~60 words start to read like mini-posts. They get ignored or, worse, look like an attention grab.
Tight comments with one sharp specific outperform long thoughtful comments almost every time - and they're easier to write consistently.

Quick questions.
How is this different from the Chrome extension?
This tool uses a generic voice. The Chrome extension uses your voice - built from your brand profile, a short calibration, and the samples you give it, then sharpened every time you edit a draft before posting. Same engine, different inputs.
Is auto-commenting allowed by LinkedIn?
No - and we'd never build it. This tool drafts a comment. You paste it into LinkedIn and click Post. Manual, every time.
How many comments per day should I actually leave?
10-15 thoughtful ones beats 50 quick ones. The Chrome extension builds you a punch-list so you do it in 15 minutes, not an hour of scrolling.
Will the post author know I used AI?
Not if you edit. The tool gives you the skeleton; you add the specific - a real number, a real memory, a real reaction. That's the part AI can't fake.
Can I use this for X / Reddit / Substack?
Soon. Today the tool is tuned for LinkedIn's tone. X, Reddit and Substack-flavored comment variants are on the roadmap.
Comments in your voice?
The free tool runs on a generic voice. The Chrome extension runs on yours - free, no signup.
