What is it?

Biscuit Studio is a web tool for producing short English teaching videos aimed at Chinese learners. Given a grammar point, collocation, or usage scenario, it uses a large language model to draft a lesson script, storyboard, subtitle text, and video prompts, then checks the content for grammar, collocation, exceptions, etymology, and cultural background.

The pipeline then calls Seedance to generate a 9:16 silent video with a consistent character, aligns the reviewed subtitle text to the narration audio using a Doubao speech subtitle service, and uses FFmpeg to burn in Chinese subtitles with highlighted English keywords. Users can batch topics, run a task queue with retries, and download both the raw clip and the subtitled version. Fixed output length is 30 seconds.

The project is a FastAPI backend with a Vite and React frontend, deployed with Docker Compose and Nginx. Users supply their own Volcano Engine Ark API key and endpoint IDs in the browser, and history is kept locally in the browser for seven days.
