Knowcast launches an AI tool that generates explainer videos from prompts, with voice cloning and visual storytelling features.

Knowcast turns a topic, article, or lesson into a structured explainer video by converting a prompt into visual scenes, captions, and narration without requiring manual frame-by-frame editing.

The tool includes voice cloning, which captures a user's tone, pacing, and pauses from a short recording so their own voice can be reused across multiple videos and narration.

Use cases span YouTube explainers, TikTok and social education, online lessons, and product walkthroughs; pricing starts free and scales as video creation becomes part of a user's regular workflow.
