Spira Maxima Spira Maxima is a video generation model that turns a plain-text script into a finished, ready-to-post social video in one pass, complete with an AI presenter, on-trend B-roll, captions and music. Users can supply a photo and voice for a personal AI clone, product shots or existing recordings, and the model builds the edit around those assets. It is post-trained on social trend and performance data so every video follows formats currently driving engagement.
