What's a hook?
A hook is the opening line of a social media post — the first thing people see in their feed. On X (Twitter) it's the first line of your post or thread. On LinkedIn it's the first one or two lines shown before the "...see more" fold. Its only job is to stop the scroll and earn the next line.
Hooks matter because feeds are ruthless: most people decide whether to read your post in under a second, based on the opening line alone. The same post can get 100 views or 100,000 depending on how it starts. That makes the hook the highest-leverage sentence you'll write, and also the hardest one to start from a blank page.
This AI hook generator gets you past that blank page. Describe what your post is about, pick X or LinkedIn, and it writes 10 hooks in different proven styles — bold claims, specific numbers, curiosity gaps, story openers, and more. Pick the angle that fits, make it sound like you, and write the rest of the post knowing the first line already works.
The 6 hook types this generator uses
Great hooks aren't random. Almost every high-performing opener on X and LinkedIn follows one of a handful of proven patterns. The generator above deliberately mixes these angles so you can see which one fits your topic best.
The bold or contrarian claim
Open with a statement most of your audience disagrees with, then spend the post backing it up. “Cold email is dead” or “Most productivity advice makes you slower.” Disagreement is the fastest route to a reply, and replies feed the algorithm.
The specific number or result
Concrete numbers beat vague claims: “I grew from 0 to 12,400 followers in 90 days” stops more scrolls than “I grew fast.” Specificity signals a real story, and real stories earn the click on “see more.”
The curiosity gap
Tease the payoff without giving it away: “The one metric I check before writing any post.” The reader has to open the post to close the gap. Use it honestly, though. If the payoff doesn't deliver, you've traded trust for one click.
The mistake or warning
“I wasted $30k on ads before learning this” or “Stop doing X before it costs you Y.” Loss aversion is stronger than the promise of a gain, so warnings routinely out-hook tips with identical content.
The personal story opener
Drop the reader mid-scene: “Two years ago I was answering support tickets at 2am.” Stories create an open loop the reader wants resolved, and first-person specifics are the hardest hook for competitors to copy.
The direct question
“What would you do with 10 extra hours a week?” A good question makes readers answer in their head before they've decided to read. Works best when the question is one your exact audience keeps asking itself.
How to get the most out of generated hooks
A hook generator gets you past the blank first line in seconds. These tips make sure the hook you pick actually earns the read, and keeps the followers it attracts.
Treat generated hooks as starting points
The best use of an AI hook generator isn't copy-paste, it's picking the angle that fits and rewriting it in your own words. Swap in your real numbers, your actual story, your vocabulary. A slightly rougher hook that sounds like you beats a polished one that sounds like everyone.
Match the hook to the post behind it
A hook is a promise, and the post is the payoff. If the hook promises a lesson, deliver a lesson; if it opens a story, finish the story. Hooks that over-promise get the click and lose the follower, and on LinkedIn especially, dwell time after the click is what the algorithm rewards.
Front-load the interesting part
On X you have roughly one line, and on LinkedIn about 140-210 characters before the fold cuts you off (less on mobile). Put the number, the tension, or the claim in the first few words. If your hook warms up with context before getting to the point, cut the warm-up.
Test different hooks on the same content
The same post can flop or take off depending on its first line alone. Generate several hook angles, publish the strongest, and note which styles your audience responds to. Over a few weeks you'll learn whether your readers bite on numbers, stories, or contrarian takes.
Frequently Asked Questions
Everything you need to know about writing hooks and using this free AI hook generator.
What is a hook in a social media post?
A hook is the opening line of a post — the first thing people see in their feed. On X (Twitter) it's the first line of a post or thread; on LinkedIn it's the first one or two lines before the "...see more" fold. Its job is to stop the scroll and convince the reader to keep reading.
How does this AI hook generator work?
Describe what your post is about, pick X or LinkedIn, and the tool uses large language models to write 10 hooks in different proven styles — bold claims, specific numbers, curiosity gaps, story openers, questions, and warnings. Results come back ranked strongest first, each labeled with its style. You can copy any hook or open it directly in Typefully to write the rest of the post.
Is this hook generator really free?
Yes. It's completely free and requires no account, login, or credit card. There are fair-use rate limits to keep it available for everyone, but within those you can generate as many hooks as you need.
Does it generate hooks for both Twitter and LinkedIn?
Yes. Use the platform toggle to switch between X (Twitter) and LinkedIn. The tool adjusts hook length and style for each platform: shorter, punchier first lines for X, and hooks written to fit before LinkedIn's "...see more" fold.
How long should a hook be?
On X, keep the first line under roughly 100-120 characters so it reads in one glance. On LinkedIn, only about the first 140-210 characters show before the "...see more" fold (less on mobile than desktop), so the tension or promise of your hook needs to land inside that window. This generator keeps hooks within those limits automatically.
What makes a good hook?
A good hook is specific, creates tension or curiosity, and makes a promise the rest of the post actually keeps. Concrete numbers beat vague claims, warnings beat generic tips, and stories beat announcements. The most common mistake is warming up with context instead of leading with the interesting part.
What are examples of good hooks?
A bold claim: "Most productivity advice makes you slower." A specific result: "I grew from 0 to 12,400 followers in 90 days. Here's the system." A curiosity gap: "The one metric I check before writing any post." A story opener: "Two years ago I was answering support tickets at 2am." Each works because it's specific and creates tension the rest of the post resolves.
Should I use the generated hooks word for word?
You can, but the hooks work best as starting points. Pick the angle that fits your post, then swap in your real numbers, your actual story, and your own vocabulary. A hook that sounds like you keeps the followers that the click earns.
Will the hooks sound like AI wrote them?
The generator is instructed to write in plain, conversational language with no hashtags, emojis, or clickbait patterns. That said, the fastest way to make any hook sound human is to edit in a personal detail only you could know — a real number, a real moment, a real mistake.
Which hook styles perform best?
There's no universal winner — it depends on your audience and topic. Specific numbers and personal stories tend to be reliable starting points because they're hard to scroll past and hard to fake, while contrarian takes earn the most replies when you can genuinely defend them. The practical answer: generate several styles, publish the strongest, and track which ones your audience responds to over a few weeks.
Does the hook affect how far my post reaches?
Indirectly, yes. Both X and LinkedIn distribute posts based on early engagement signals — stops, expands, replies, and time spent reading. The hook is what earns those first signals: a post nobody stops for never gets the engagement that triggers wider distribution. That's why the same content can perform completely differently depending on its opening line.
Can I generate hooks for a thread?
Yes. A thread's first tweet is a hook, so describe the thread's topic, pick X as the platform, and use the strongest result as your opening tweet. You can then open it in Typefully and write the rest of the thread in the same editor.
Can I schedule the post from here?
Not from this page directly. Once you've picked a hook, use "Use" to carry it into a new Typefully draft, where you can write the full post, preview it for each platform, and schedule or queue it for X and LinkedIn.
