AI hook generator for short-form videos

Type what your video is about and get five scored opening lines - bold questions, shocking statements, and curiosity gaps, ranked by scroll-stopping power. Free, instant, no account needed.

What is your video about?

Free, no sign-up. Scores rate scroll-stopping power from the line's length, curiosity gap, and urgency signals.

Why the first line decides everything

Short-form feeds are auctions for attention, and the opening line is your bid. Platform analytics consistently show the steepest drop-off in the first three seconds: if the hook does not open a question in the viewer’s head, the swipe happens before your content even starts.

Strong hooks share mechanics: they are short enough to land in one breath, they name something concrete, and they open a gap the viewer needs closed. That is exactly what this generator writes and scores - five different angles on your topic, ranked so you can pick the strongest opener instead of guessing.

Five styles, because topics differ

A shocking statistic wants a bold statement. A personal story wants a first-person intro. A mystery wants a curiosity gap. The generator always writes one hook in each of five proven styles - bold question, bold statement, shocked reaction, character intro, and curiosity gap - so you see which angle fits your topic instead of five variations of the same sentence.

The same five styles power the Hook section inside FrameCompose’s Video Studio, where the chosen hook becomes scene one of a generated video: the script is written to flow from it, and the opening visual is composed to match.

From hook to finished video in one click

A hook is only the first second of the job. Click "Turn into a full video" on any result and Video Studio opens with your topic and hook pre-loaded: it plans the scenes, generates AI visuals, records an AI voiceover, and syncs word-by-word captions - all on a real timeline where every scene stays editable.

Unlike one-shot generators, you fix single scenes without regenerating the whole video, and edits after generation are free.

How the scoring works

The score is a deterministic craft rating, not a virality promise. It rewards the measurable habits of hooks that hold: a spoken length around 6 to 14 words, a direct question or a concrete number, addressing the viewer as "you", urgency and curiosity words, and staying grounded in your actual topic. It penalizes weak openers like "in this video we will…" - the fastest way to lose a feed.

Frequently asked questions

A few quick answers before you jump in.

What is a video hook?

The hook is the first line of your video - the sentence that plays in the first one to three seconds. On TikTok, YouTube Shorts, and Instagram Reels, viewers decide whether to keep watching almost instantly, so the hook has one job: earn the next three seconds. A weak opener is the single most common reason short-form videos flop.

How does the hook generator score each line?

Each hook gets a 0-100 score from measurable signals of scroll-stopping power: an ideal spoken length (roughly 6 to 14 words), a question or a concrete number, direct address ("you"), curiosity and urgency words, and how grounded the line is in your actual topic. Lines that open with filler like "in this video" lose points.

Is the hook generator really free?

Yes. You get a batch of AI-written hooks free each day without creating an account. If you hit the daily limit, the tool still builds template hooks from your topic, and a free FrameCompose account unlocks hook writing inside the full video generator.

What hook styles does it write?

Five proven short-form styles: a bold question the viewer cannot scroll past, a bold statement that demands proof, a shocked reaction ("No. Way. This actually happened."), a first-person character intro, and a curiosity gap that opens a specific question the video answers.

Can I turn a hook into a full video?

Yes - that is what FrameCompose does. Click "Turn into a full video" on any hook and Video Studio opens with your topic and chosen hook pre-loaded. It writes the script to flow from your hook, generates AI visuals and voiceover, and syncs word-by-word captions on an editable timeline.
