AI Video Hook Generator

An AI video hook generator writes the opening line of a video: the first three to five seconds that decide whether someone keeps watching or scrolls past. You describe what the video is about, pick a hook style and a platform, and a language model writes ten numbered hooks, each one or two sentences meant to be spoken on camera.

Short-form feeds give a video very little time to earn attention, and long YouTube videos lose viewers in the first seconds too. Writing one hook is easy; writing ten different angles so you can pick the strongest is where people run out of ideas. The styles are Question, Bold statement, Story, Surprising fact, Challenge, and Mix of styles. The platforms are YouTube, TikTok, Instagram Reels and YouTube Shorts. The model is told to avoid clickbait the video cannot back up, because a hook that lies gets the swipe a few seconds later instead. For a full script around the hook, the YouTube script generator writes the whole thing.

The model runs on the Toolz server. Your description is sent over HTTPS, the server builds the prompt and runs Gemma 3 1B, a small open model from Google, with Ollama, and the hooks stream back within a few seconds. Your video idea is used to write the list and then discarded: it is not stored or logged, not used to train any model, and not sent to any third-party AI company.

Keep the limits in mind. The model does not see your footage, your audience data or what is trending, so it cannot predict which hook will perform. A 1B model can also state a "surprising fact" that is not true, so check any number or claim before you say it. The real test is recording two or three hooks and comparing retention.

It is free, with no signup, within about 20 runs per 10 minutes. The alternatives are writing hooks yourself from a list of formulas, copying the structure of openings you like, or a general AI chatbot run by a large AI company.
