The workflow is three steps: describe a topic, let the tool generate scenes with captions and infographics, then export. Voice cloning lets you train on a short sample once and reuse your own tone across every video you publish — which matters when you're releasing daily and recording every session isn't viable. The free tier caps total video output at two minutes, which is enough to validate the format but not enough to build a publishing schedule around. The tool generates finished video, not editable source files you hand off to a production stack — so teams that need custom motion graphics or branded templates hit a ceiling. There is no API, which rules out automated pipelines.
