Showrunner is the flagship product of Fable, the San Francisco AI entertainment studio co-founded by Edward Saatchi (formerly of Oculus Story Studio). Dubbed the "Netflix of AI," it opened to the public in July 2025 alongside an undisclosed investment from Amazon's Alexa Fund.
How it works
Users type a few words and Showrunner generates scenes or full animated episodes — dialogue, voices, shots and storylines — inside persistent simulated worlds built on Fable's SHOW-1 model and simulation research. Subscribers ($10–$40 per month for credits) can insert themselves as characters, remix existing story worlds, and publish serialized episodes with continuity. The flagship original, Exit Valley, is a Family Guy-style satire of Silicon Valley, and the platform spans comedy, sci-fi, horror and anime formats.
Why it matters
Fable's earlier interactive film work won an Emmy, and its 2023 South Park AI episode experiment drew industry-wide attention. With Amazon's backing and ambitions to license shows to major streamers, Showrunner is the most prominent attempt to turn generative AI into a new serialized entertainment medium rather than a production tool.
