explainroo: make and review a locally rendered explainer video

How to choose your drawing style and voice, review the scene code and check the exported explainer.

The short version

I would choose one factual topic and a short script before asking an agent to render. explainroo is an MIT tool that renders scripts and drawing scenes with local voices, timing and video encoding. Coding-agent access and optional generated illustrations are separate services with their own costs. This guide follows official docs; I have not independently run its full generation pipeline.
