AI Hook Generator

Updated September 20, 2026

Quick answer: retention is decided by where an episode stops, so the hook is built into the episode breakdown rather than bolted on as text. Every episode is required to end on an unresolved beat, and the kind rotates — identity exposed, feeling suspended, understanding overturned — so eight episodes do not run the same trick eight times. Opening shots start on the problem, and no text is ever burned into the frame.

A hook is a structural decision, not a caption

Most “hook generators” write you a line of text to paste over the first frame. That is the last five percent of the job. The thing that actually decides whether someone watches episode two is where the episode stops — and that is a decision made while the script is being divided into episodes, long before any video exists.

So hooks here are not a separate tool. They are a constraint the episode breakdown has to satisfy: every episode ends on an unresolved beat, and the kind of unresolved beat rotates so the series does not feel like the same trick eight times.

The three kinds, and why they rotate

The end-of-episode beats the breakdown cycles through
KindWhat is left openReads as
Identity exposedSomeone now knows something about who another person really is — but we cut before we see what they do with it.Dread. Works best mid-season.
Feeling suspendedA confession, an accusation or an offer lands, and the reply is the next episode's first line.Ache. Works anywhere, wears out fastest.
Understanding overturnedThe audience learns the situation was not what they were told; the characters have not caught up.Vertigo. Best saved for act breaks.

Rotation matters more than any single hook's strength. Three “feeling suspended” endings in a row train the viewer to expect a non-answer, and the fourth one stops working. The breakdown is told to alternate for exactly this reason.

The opening seconds, done as craft rather than text

The first shot of an episode carries the same weight as the last, and the shot list treats it as a distinct problem: it establishes the frame, who is in it, and what is wrong — in that order, in one shot, without a line of exposition. Concretely, what the list is made to avoid:

Where you can see and change it

The episode list after analysis gives you each episode's outline — three to five sentences including how it ends. That is the cheapest place in the whole pipeline to change a hook: it is text, editing it is free, and nothing has been rendered yet. Rewrite the ending of an outline and the shot list generated from it follows.

Once a shot list exists you can still edit the script text directly, and the editor keeps the machine-readable structure in sync as you type. What you cannot do is bolt a hook onto finished video — that means regenerating the segment, which costs what a segment costs.

What it will not do

What it costs

Hooks cost nothing extra: the episode breakdown that produces them is part of the analysis pass, billed by script length at 4 credits per thousand characters (3,333 characters per unit for alphabetic scripts). Per-episode shot lists are 1 credit per hundred characters of that episode's share, and editing outlines or script text is free. Only rendering costs money: from 10 credits per second of output. New accounts get 50 credits and one free preview of up to 5 seconds. See the episode generator page for how episodes are divided, and the pricing page for full rates.

Frequently asked questions

Will it write the text I put on the first frame?

No, and deliberately. Nothing is rendered as text in the video — video models cannot produce reliable lettering — so caption and hook copy go on at the platform, where you can change them per post without re-rendering a shot.

Can I choose which kind of ending an episode gets?

Yes, by editing that episode's outline before generating its shot list. Outlines are plain text and editing them is free; the shot list is generated from whatever the outline says.

Does every episode really need a cliffhanger?

For short vertical drama, effectively yes — that is the format's engine. For a feature-length project the breakdown paces differently, because a film does not need to reacquire its audience every ninety seconds.

What if the hook it writes is weak?

Rewrite the outline sentence and regenerate the shot list for that episode. It is the cheapest correction available: text in, text out, no rendering involved.

Can I add a hook to an episode I have already rendered?

You can change the script, but the segments after the change have to be rendered again — finished video is not editable text. This is why the outline stage is the place to get endings right.

Fix the ending while it is still a sentence

Outlines are free to edit. Rendered video is not.
