Frequently asked
What makes a good hook?+
It creates a gap the reader needs closed — a bold claim, a specific number, a contrarian angle or a callout to a specific person. The job of the first line is to earn the second line, nothing more.
Is the hook generator really free?+
Yes — no sign-up, no card. There's a fair daily limit to keep it free for everyone. When you want the whole post (slides, design, AI images and a caption), that's what the full Caruva app does.
Which platforms do these hooks work for?+
All of them — Instagram, TikTok, LinkedIn, X, YouTube. A strong hook is platform-agnostic; you just adjust length. Caruva can then format the full post for the platform you choose.
How do I write a hook? (the simple formula)+
Open a gap and promise to close it. The reliable formulas: a specific number (“3 mistakes that…”), a contrarian take (“stop doing X”), a callout (“if you post and no one saves it…”), or a curiosity gap (“nobody tells you this about…”). Lead with the value, never with a warm-up sentence. The first line’s only job is to earn the second.
What are some hook examples?+
“You’re not bad at this — you’re just using the wrong template.” · “5 mistakes that quietly kill your reach.” · “I grew to 10k with one boring habit.” · “Most morning-routine advice is procrastination in disguise.” Notice the pattern: specific, a little contrarian, and they leave you needing the next line.
How long should a hook be?+
One or two short lines — whatever shows before the “more” cutoff or on the first slide. If the reader has to work to find the point, you’ve already lost them. Shorter and sharper almost always beats longer and complete.
