How it works
From an idea to a narrated math animation in three steps.
Your agent plans and renders
The agent uses built-in guidance to prepare the storyboard, check the visuals, and render with local narration.
lemmareel preview --project ./my-video
lemmareel qc --project ./my-videoGet your video
Export a narrated 1080p MP4 to share or use in your teaching. Keep the project and iterate with your agent.
lemmareel export --project ./my-videoBuilt for your workflow
Connect the coding agent you already use.
Codex
Description and PDF to MP4 verified in development.
Claude Code
Project connector included; full workflow validation pending.
Gemini CLI
Project connector included; full workflow validation pending.
Render on your computer
Rendering and narration run locally. Your AI agent uses its own model provider.
Two ways to install
Let your agent do it, or run the installer yourself.
Install with your AI agent
Copy one prompt into Codex, Claude Code, Gemini CLI, or any agent that can run commands. It installs LemmaReel, checks the rendering tools, and connects itself — no license to type.

- 2Copy the install prompt
- 3Paste into your agent
Uses your LemmaReel account. The code inside the prompt works on one computer, expires in 1 hour, and activates that computer as your one licensed device. macOS and Linux; Windows is not supported yet.

Separate from Web Studio
CLI licenses and Studio credits are not interchangeable. This purchase includes no Studio credits. Your coding agent’s subscription and model usage are separate.
