Video hook generator for short-form video
The first line of a short video decides whether the rest of it gets watched. Enter a topic and this generator returns six ready openers in a single pass — one drawn from each of five angles that reliably stop a scroll (curiosity, contrarian, mistake-or-warning, list, and transformation), plus a sixth from the mix — each labeled with its angle and filled with your topic, so you leave with usable first lines instead of blank-page advice.
To be clear about what this is: it is a template tool, not an AI writer. The structures are hand-written and proven; you supply the topic and the generator fills the blanks. That makes it fast and predictable, but the wording still wants a human pass to sound like you. If you want the full script written for you rather than just the hook, that is Reelsta’s paid product — this tool is the free, browser-only warm-up.
Hook generator
Curated templates, not AI — they’re written to be edited to fit your angle, not pasted blindly.
How to use it
- 1
Enter your topic
Type the subject of the video in a few words — the fact, the story, the claim (for example, "sleep habits of astronauts"). The generator drops your topic into every template, so a specific topic produces a sharper hook than a vague one. A topic is required; there is nothing to fill the blank with otherwise.

Generate the set
Hit generate and you get six openers at once — one from each of the five angles and a sixth from the pool — with a category tag on each. You do not pick an angle up front; seeing the same topic reframed five ways side by side is how you find the framing that fits the video you actually have. Re-roll for a fresh set anytime.

Copy, tweak, and test
Click Copy on the two or three that fit, adjust the wording to your own voice, and try them on real posts. The template gives you the structure; only testing on your own audience tells you which structure wins.
Frequently asked questions
Is the hook generator free to use?
Yes — free, no signup, and it runs in your browser. Type a topic and generate as many hook variations as you want; nothing is saved or uploaded.
Is this an AI hook writer?
No, and we would rather say so plainly. These are curated, fill-in-the-blank templates — hand-written structures that drop your topic into a proven pattern. There is no model generating novel lines here. Reelsta’s paid product is where AI writes full, original scripts.
What actually makes a hook work?
A hook works when it opens a loop the viewer needs closed — a curiosity gap, a claim that contradicts what they assume, or a stake they recognize. Specificity beats intensity: naming the exact detail or the exact audience stops more scrolls than turning up the drama.
How many hooks should I test before settling?
Generate several angles for the same topic and post a few over time rather than betting everything on one. The angle that wins is often not the one you expected, and the only reliable judge is your own retention graph.
Can Reelsta write the whole script, not just the hook?
Yes. This free tool hands you an opener; Reelsta, as a paid subscription, writes the full script for your topic, narrates it in one of its native AI voices, generates the visuals in any of 14 art styles, captions it in 9 styles, and auto-posts to TikTok, YouTube Shorts, and Instagram Reels — with an edit-before-post step so you keep the final say and full ownership.
