SocialAgentFree hook generator
Twelve opening lines for your topic, grouped by the mechanism that makes each one work.
A hook has one job: make the second line unavoidable. This tool fills proven hook formulas with your topic and labels the mechanism behind each — curiosity gap, stakes, contradiction, specificity, or a plain promise — so you can pick deliberately instead of guessing.
These work for text posts, carousel slide one, and the first three seconds of a reel or short. The formula is the same; only the delivery changes.
How to use it
- Enter your topic as a noun phrase: "cold email", "sourdough", "pricing creative work".
- Generate, then read the mechanism label next to each hook. That tells you why it works.
- Pick two, not one. Post one now and keep the other for the same idea in a different format.
- Cut every word that does not change the meaning. Hooks get stronger as they get shorter.
Tips that actually change results
- Specific beats clever. "I tried this for 30 days" beats "the surprising truth about".
- A number in the hook sets an expectation the reader wants to close. Three items feels finishable; twelve feels like homework.
- Never open with a question the reader can answer "no" to and leave.
- If the hook promises something the post does not deliver, you buy one view and lose a follower.

Is the hook generator free?
Yes. It runs in your browser with no login and no API key.
What makes a good hook?
A good hook creates a gap the reader wants closed within the first line: an unexpected claim, a concrete number, a stake, or a contradiction of something they believe. Vagueness kills hooks faster than bad writing.
Can I use these hooks for reels and shorts?
Yes. The same formulas work spoken in the first three seconds of a video, on slide one of a carousel, or as the first line of a text post.
Should I reuse a hook that worked?
Yes, on a different topic. A hook formula that performed once will usually perform again — audiences respond to the shape, not the novelty.
