CodeKitHubWhat Is This Tool?
LinkedIn Comment Generator recreates LinkedIn's real comment section — each commenter shown with an avatar, name, professional headline, comment text, like count and optional reply indentation — so you can mock up realistic engagement for a post preview.
It must never be used to fabricate fraudulent evidence, harass or defame someone, or impersonate a real person's actual comments — doing so may be illegal depending on your jurisdiction.
Everything is generated locally in your browser using the HTML Canvas API; nothing is ever uploaded to a server.
Why Use It?
- You're about to post a case-study announcement and want to see whether the layout still looks balanced once three or four realistic replies stack up underneath it, before you actually publish and wait for real comments to arrive.
- A recruiter is building an internal training deck on "what a high-engagement recruiting post looks like" and needs a realistic comment thread example with names and headlines, without pulling screenshots of real candidates' comments.
- A sales team is putting together a pitch deck slide that shows what strong social proof under a company post looks like, using placeholder commenters instead of real client names that would need legal sign-off.
- You're testing whether a nested reply makes a thread feel more like a genuine conversation versus a wall of unrelated top-level comments, before deciding how to structure your own reply strategy.
- 100% local rendering, no account and no watermark — just add commenters and download.
How to Use
- Type the original post text at the top of the thread.
- Add commenters with a name, professional headline, comment text and like count.
- Toggle a comment as a nested reply to indent it under the thread.
- Watch the live preview update, then click "Download PNG" to save the image.

Responsible use
This generator exists to make it easy to create clearly fictional comment-thread mockups for previews and presentations. If you share an image made with this tool, consider adding context so viewers understand it is not a real comment thread.
What makes a comment thread mockup look realistic
A convincing LinkedIn comment thread mockup isn't just about adding names — it's about mimicking the small patterns real threads follow. The table below covers what to vary so the result doesn't look artificially uniform.
| Element | Realistic pattern | Common mistake |
|---|---|---|
| Like counts | Vary widely — a few comments with 20+, most under 10 | Giving every comment the same round number like 10 or 20 |
| Headlines | Mix of relevant roles (recruiter, peer, client) | Using the same job title for every commenter |
| Reply depth | One or two nested replies max under a popular comment | Nesting every comment, which no real thread does |
| Comment length | Mix of one-liners and a couple of longer, thoughtful replies | Making every comment the same length |
Frequently Asked Questions
Is it legal or ethical to use this tool?
The tool itself is legal to use for entertainment, mockups, presentations and design work. What is not legal or ethical is using the generated image to deceive someone. Please only use this for clearly fictional or illustrative purposes.
Does the tool upload my content anywhere?
No. Everything you type stays in your browser's memory and is drawn directly onto a canvas element with JavaScript. The PNG is generated and downloaded on your device — nothing is ever sent to a server.
How many commenters can I add?
You can add as many commenters as you like using the "Add message" button, and remove any of them individually. Each one can be marked as a top-level comment or an indented reply.
Can each commenter have a different headline?
Yes — every commenter gets their own name, professional headline, avatar color and like count, matching how LinkedIn shows each person's role under their name in a real comment thread.
Can I nest a reply under a specific comment, or does it just indent the last one?
Each comment has its own reply toggle, so you decide exactly which comments are top-level and which are indented as replies, letting you build multi-level conversations rather than a single flat list.
Can I show the original post text along with the comments?
Yes — there's a dedicated field for the original post text at the top of the thread, so the comments read as responses to something specific rather than floating on their own.
Does this connect to LinkedIn's real API or post anything live?
No. This tool has no connection to LinkedIn — it only draws a preview image locally in your browser. Nothing you type here ever appears on the real LinkedIn platform.
Can I reorder commenters after adding them?
Yes, you can remove any commenter and re-add them in a different position, letting you control which comment appears first — useful for putting your strongest example reply at the top of the mockup.
