Pocket FM Releases Free Sherpa AI Tool to Help Audio Fiction Writers Maintain Narrative Consistency Across Hundreds of Episodes

Pocket FM, the audio series platform with 200 million listeners worldwide, launched Sherpa in August 2025—a free artificial intelligence writing assistant designed to help creators compose long-form serialized fiction while maintaining character and plot consistency across dozens or even hundreds of episodes. The tool addresses a persistent challenge in long-form storytelling: frontier AI models typically struggle to hold narrative threads together beyond a few chapters, often introducing contradictions or losing track of character arcs and world details as stories expand.
