One prompt. Four stages. A finished course.
Nothing here is a black box — you can watch every stage run and open every file it produced.
- 01
Describe the lesson
Type or speak your topic. Set the format (video, slides, audio), the language, the level, how many modules and lessons you want, and whether you want citations. That is the whole setup.
- 02
Juci plans the course
Juci — the teaching agent — drafts the outline to the structure you asked for, sizes each lesson to the length you named, then writes the narration script for every module. Say nothing about structure and it proposes a short one.
- 03
Assets are generated and mixed
Narration voice, a background music bed, illustrations, and (for filmed courses) video clips are generated per module, then assembled with a time-synced transcript. Each step shows up as its own card in the build panel with the files it produced.
- 04
Watch, answer, certify
Play the course with captions, fullscreen, and click-to-seek transcript. Each lesson ends with a quiz; 70% or better across the course issues a certificate with a public verification link.
What makes it hold up
Builds survive closed tabs
Generation runs server-side on durable workers. Close the laptop; the build keeps going and the finished course shows up in your library.
Nothing is regenerated twice
Every render is tracked by job. If a provider is slow or a run is interrupted, Juicee recovers the clips that already exist instead of paying to make them again.
You see the cost, not a mystery bill
Credits are spent per rendered asset: 8 credits per minute of audio, 32 for slides, 286 for filmed video. One credit is one cent.
Your library is searchable
Courses, chats, transcripts, and generated files are indexed. ⌘K jumps to any of them.
Full credit breakdown lives on pricing.
