Post looks ready?The first hour decides its reach. Get real likes and comments from LinkedIn professionals right after you post.
Boost it freePaste your draft and see it the way your network will: on mobile or desktop, light or dark, with the exact spot where LinkedIn hides the rest behind "…more". Fix the hook before anyone scrolls past it.
The LinkedIn post box shows your draft as one long block of text. It does not show you what people actually see in the feed: your first two or three lines, then "…more". Everything after that cut is only read by people who were curious enough to tap.
That is why the opening matters so much. If the line that makes people stop sits below the cut, most readers never reach it. A preview shows you where the cut lands on a phone and on a computer, so you can move your strongest line up before you post.
This tool also checks the basics while you type: the length of your first line, your character count against LinkedIn's 3,000 limit, how many hashtags you use, and whether you end with a question. You can add an image, switch to dark mode, and copy the finished text straight into LinkedIn.
Type into the editor or paste a draft. Add your name and headline if you want the card to look like yours. The preview updates as you type.
Switch between Mobile and Desktop. Mobile cuts the post earlier, so check it first. Click "…more" in the preview to see the full post, and switch on dark mode to see how it reads there.
Under the editor you will see your character count, word count and read time, plus quick checks on your hook, the cut-off, hashtags and your closing line. Adjust until you are happy.
Click Copy post text and paste it into the LinkedIn post box. Line breaks, bold and italic text and emoji all carry over.
Everything runs in your browser. There is nothing to install and no account to create.
Most LinkedIn reading happens on phones, where the post is cut earlier. Switch views with one click and see both before you publish.
The preview cuts your post where LinkedIn roughly does: about 140 characters or three lines on mobile, about 210 on desktop. The checklist tells you how many characters people see before the cut.
Instant checks for a short first line, the 3,000 character limit, hashtag count and a closing question that invites comments.
Select text and make it bold or italic, or turn lines into a bullet list. The styled text survives the copy and paste into LinkedIn.
Add the image you plan to post to see the whole card, and switch the preview to dark mode, which many people use on LinkedIn.
Your post never leaves your browser. Nothing is saved or sent to a server, so you can preview drafts you are not ready to share.
LinkedIn does not publish an official number, and it tests changes. These are the limits most people see today, and the preview uses them.
On the LinkedIn app, posts are cut after roughly 140 characters or the third line break, whichever comes first. A one-line hook followed by a blank line and a second line already uses two of those three lines.
On a computer the feed is wider, so more text fits before "…more". A post that looks complete on desktop can still be cut halfway through a sentence on mobile. Always check the mobile view first.
The words before the cut have one job: make people want the rest. A specific result, a surprising admission or a clear promise usually works better than a greeting or background.
A quick reference for the limits you hit when you write a post.
A LinkedIn post can be up to 3,000 characters, including spaces, line breaks and emoji. The counter in this tool turns red if you go over, so you can trim before LinkedIn stops you. If your idea needs much more room, a LinkedIn article is a better home for it.
Hashtags still work as links on LinkedIn, but a long row of them makes a post look like an advert. Three or fewer, placed at the end, keeps the post clean. The tool flags it when you use more.
A paragraph that looks short on a laptop can fill a phone screen. Break your post into lines of one to three sentences, with a blank line between them. The mobile preview shows you straight away if a block feels heavy.
A good preview gets people to read your post. What happens in the next hour decides how many people see it.
LinkedIn first shows a new post to a small part of your network. If those people react and comment, it shows the post to more of them, and then to their networks. A post that gets little response early usually stops spreading.
HyperClapper connects your post with real LinkedIn professionals who like and comment within the first hour, so the post has the early response it needs to keep spreading. Write it here, preview it, publish it, then boost it.
A short walkthrough of how a good post plus a strong first hour helps you grow.

Not inside LinkedIn's post box in a way that shows the feed view and the "…more" cut. This tool does: paste your draft and you see it as a LinkedIn card on mobile and desktop before you publish.
Yes. It is free with no sign-up and no limit on how many posts you preview.
Roughly after 140 characters or three lines on mobile, and about 210 characters on desktop. LinkedIn does not publish an exact number and changes it from time to time, so treat these as close guides.
3,000 characters, including spaces, line breaks and emoji. The counter in the tool shows how close you are.
Yes. The tool uses Unicode letters that look bold or italic, so they stay styled when you paste them. Use them for a few words only, because screen readers and LinkedIn search treat them differently from normal letters.
Yes. Click Image to add the picture you plan to post and it appears in the preview card under your text.
No. The tool runs entirely in your browser. Nothing you type is stored or sent to a server.
