Reelava creates narrated videos from a title or script. It assembles research, script, narration, scenes, visuals, motion, captions, music, and an MP4 for human review. It supports vertical 9:16 and horizontal 16:9 output. A free plan is available without a card and exports with a watermark. Reelava is best suited to faceless explainers, curiosities, storytelling, and educational videos; it is not a timeline editor, and generation time varies.
