Free LinkedIn post preview
See exactly how your LinkedIn post looks in the feed — before you publish. Nail the hook before the “see more” cutoff.
Your details
On desktop, the feed shows about the first 210 characters before collapsing. You are using 210 of them. The rest hides behind the “more” link.
Most people scroll past the first line. The ones who stop? They read a hook that made a promise in under 210 characters.…
A faithful mock for planning. Reactions are illustrative; nothing is posted or saved.
Why the first 3 lines decide everything
In the feed, almost no one sees your whole post at first. They see the opening lines, then a “see more” link. That preview is the only thing standing between a scroll and a read, so it is worth getting right before you hit publish.
~2%
Only about two percent of LinkedIn members publish in a given week. The other 98 percent stay quiet, so a clear post with a strong opener already puts you in rare company.
+1,182
People who publish weekly tend to earn far more reach, on the order of an extra 1,182 impressions per post and roughly three times the engagement. The hook is what gets that reach moving.
Think of the preview like a subject line. The body can be excellent, but if the first three lines do not earn the tap, the body is never read. Write the opener for the cutoff, check it here on desktop and mobile, then publish with confidence.
Hook patterns that earn the click
Four ways to spend your first 210 characters so readers tap “see more” instead of scrolling past.
Open with one sharp claim
Lead with a single, specific statement people can agree or argue with. Save the setup and the backstory for after the fold. The first line should make a promise the rest of the post pays off.
Break the line early
Put a hard line break after your first sentence. White space pulls the eye down and makes the opener feel light, so the reader commits to the next line before they decide to scroll on.
Create an open loop
Name the payoff without giving it away: the mistake you made, the number that surprised you, the step most people skip. Curiosity is what turns the 'see more' tap from optional into automatic.
Cut the throat-clearing
Delete 'I'm excited to share' and 'In today's post'. They burn your best 210 characters on filler. Start where the value starts, then read the opener back on mobile to be sure it still lands.
Frequently asked questions
Is this LinkedIn post preview tool free?
Yes. The preview tool is free to use with no signup, no account, and no card. It runs entirely in your browser, so you can draft and check as many posts as you like.
Is the preview accurate to how LinkedIn looks?
It is a faithful mock of a feed post: avatar, name, headline, the '• 1st' tag, a 'now' timestamp, the body text, and the like, comment, repost, and send row. The 'see more' cutoff is an approximation, because the real fold depends on viewport width and font rendering. Use the desktop and mobile toggle to see how the cutoff moves, then treat the highlighted opening as your hook.
Where does the 'see more' cutoff fall?
LinkedIn collapses a feed post at roughly the first three lines, which is about 210 characters on desktop and fewer on a narrow mobile column. Anything after that hides behind the 'more' link. The tool highlights the text above the fold and flags when you run past it, so you can frontload the part that earns the click.
Does this tool store my post text?
No. Your text never leaves your device. The post, your name, and headline live only in the page while it is open, and the optional avatar is read in your browser with FileReader into an in-memory image. Nothing is uploaded or saved on a server, and a refresh clears it.
Can I preview LinkedIn carousels or document posts here?
Not yet. This tool previews single text posts and the feed fold around them, which is where most posts win or lose attention. For carousels and document posts, Blendin builds on-brand slides and shows them in context before you publish.
Why does the preview look different on mobile?
A mobile feed has a narrower column, so fewer characters fit on each line and the post collapses sooner. Switch the device toggle to mobile to see the tighter cutoff. If your hook still reads clearly there, it will read clearly everywhere.
Write hooks that don’t sound like AI
Previewing the fold tells you where the hook has to land. Blendin’s anti-AI writing engine helps you fill it with an opener that sounds human, then turns the idea into a full post, carousel, or image. Free to start — 50 credits a month, no card.
