AI short drama generator for vertical series
Plan a vertical drama the way the apps do: hook, escalation, cliffhanger — with a video prompt ready for every shot.
In shortCastfic is an AI short drama generator for vertical series. From one logline it writes the cast with fixed looks, a 10-episode arc and episodes 1–3, each split into 5–7 shots with a text-to-video prompt you can paste into Kling, Veo, Runway or OpenArt. 1 free scene without an account, then 1 a day with Google sign-in.
How to make an AI short drama with Castfic and a video tool
- Generate the drama here from a logline and a genre.
- Open the storyboard and copy the video prompt for shot 1.1.
- Paste it into your text-to-video tool in 9:16, then do the next shot.
- Cut the clips together, add the dialogue as captions, and post the episode.
Why the prompts keep your characters consistent
The usual problem with AI video series is that the lead looks different in every clip. Castfic writes one fixed description of each character's look in the series bible and repeats it, word for word, inside every shot prompt that character appears in. Each prompt also names the framing, the location, the lighting and the vertical 9:16 format, so it works on its own in any tool.
| Shot | Framing | Prompt starts with |
|---|---|---|
| 1.1 | CU | Vertical 9:16, close-up. A woman in her late 20s, sharp black bob, grey maid's uniform… |
| 1.2 | WS | Vertical 9:16, wide shot of a marble foyer at night, chandelier lit… |
| 1.3 | OTS | Over the shoulder of a tall man in a navy suit, silver watch… |
Where it fits with AI video tools
Video generators such as OpenArt, Topview or Kling are good at turning a prompt into a clip, but most ask you to sign in and spend credits before you see anything, and leave the story to you. Castfic does the part before that: the season, the scripts and the shot list. Use both — write here for free, render where you like.
Genres the vertical apps run on
- Revenge: the wronged lead returns under a new identity.
- CEO romance: a contract relationship with a powerful heir.
- Hidden identity: the one everyone underestimates is secretly in charge.
- Werewolf and fantasy: rejected mates, rival packs, fated bonds.
- Family secrets, thriller and comedy for something different.
