What it makes

A character narrates a short film that explains a topic: a script, keyframes, animated shots, on-camera lines, narration, a score, a hand-lettered end card and word-by-word subtitles. 50 ready narrators, 26 illustrated looks, 74 languages, 1 to 10 minutes long. You can also invent a character, upload your own, or bring your own illustration style.

How it works

Everything runs in your browser with your own fal key.


_{Pick a topic, a narrator, a look, a voice and a length}	_{Watch, share or download the finished film}

Script. A director writes the story in blocks, each either voice-over or the narrator talking on camera, and a script editor smooths every jump between scenes.
Narrator and keyframes. The narrator gets a model sheet and a hero portrait, and every block gets a keyframe in the chosen look.
Voice. Each block is narrated, and on-camera lines are fitted to the right length.
Shots. Voice-over blocks become animated shots and on-camera blocks become lip-synced shots.
Score and edit. A score is composed, the shots are cut to the narration, the sound is mixed, an end card is lettered and subtitles are added.

Make one with your agent

Every page has a Copy agent prompt button. It copies a step-by-step brief of this pipeline, filled in with the page's topic, look, narrator and voice, so a coding agent with a fal key can make the film from your terminal.

Run locally

cd web && npm install && npm run dev

cd share && npm install && npx wrangler login
npx wrangler d1 create storycast
npx wrangler r2 bucket create storycast-media
npx wrangler d1 execute storycast --remote --file schema.sql
npx wrangler turnstile widget create storycast-share --domain <your site host> --mode managed

Put the database id and your site's address (ALLOWED_ORIGINS) into share/wrangler.jsonc, then:

npx wrangler secret put IP_SALT
