Pocket FM has launched Sherpa, an AI powered story writing partner speciallized in serialised fiction, and it is free to use in beta. Sherpa can hold a full story in memory as it grows, so episode eighty still agrees with episode one. Three agents run the work 👀 > Planner, which can map the arcs, characters, and episode beats across a season. > Feedback, focusing on reading a draft as an editor would and returning precise revisions. > Storyboard, able to keep an up to date record of every character, setting and decision.
