A Pocket FM Sherpa alternative for long-running serial fiction
Sherpa is built inside a platform for audio series. Entangled Text is an independent writing studio: the same problem — keeping a long story consistent — solved with an outline, a story bible and running continuity, and the result exported as files you take anywhere.
What Pocket FM Sherpa is
Sherpa is an AI system for writers launched by Pocket FM, the audio-series platform, in September 2026. As reported by Storyboard18, Pocket FM describes it as "Narrative Intelligence" for stories that run to hundreds of episodes: separate agents for ideation, planning, research, prose, and feedback, with a Narrative World Model that tracks characters, relationships, conflicts, and events. Pocket FM says it runs on the company’s own proprietary models. Access and terms are set by Pocket FM; check their site.
