Stop the scroll on X, LinkedIn, and Instagram with proven hook archetypes extracted from 175 top-performing social creators.

Talking about your strategy feels like progress. It's not.
Why it works: Line 1 states a comfortable belief; line 2 snaps it. Analyzed score: 5,170 with 860 replies.
Everyone tells you to personalize every cold email. Here's why that's wrong:
Why it works: Forces a re-read; readers stop scrolling to evaluate the counter-intuitive claim.
I analyzed 175 top-performing social posts last month. 3 patterns separated the top 1%.
Why it works: Specific numbers feel earned and concrete rather than generic advice.
You're addicted to vanity impressions. (And it's quietly killing your customer pipeline)
Why it works: Direct second-person accusation plus parenthetical stakes that demand resolution.
What is a social media hook generator?
A social media hook generator crafts the critical opening lines of a post. It applies psychological scroll-stopping frameworks, including two-line contradictions, parenthetical amplifiers, and disadvantage flips, to earn reader attention before feed truncation cuts off the body.
Unlike generic AI assistants that output clichéd platitudes, supapost applies proven patterns extracted from real top-performing social posts and replies. Use this free web tool for quick generation, or automate it in bulk using our REST API, n8n templates, and MCP server.

Frequently asked questions
What is a social media hook generator?
A social media hook generator creates the opening 1-2 lines of a post. Because mobile feeds truncate content after a fraction of a second, the hook is responsible for 90% of whether a user stops scrolling or continues past.
What makes a hook go viral?
Our research across 175 viral posts revealed that successful hooks do not make vague promises. They either introduce tension (two-line contradictions), challenge conventional wisdom (contrarian takes), or ground authority in specific numbers.
How do I choose between a broadcast hook and a conversation hook?
If your goal is wide viral reach and retweets, choose a broadcast hook (crisp single-sentence aphorism). If your goal is high comment ratios and relational networking, choose a conversation hook (personal vulnerability, confession, or open question).
