Pocket FM launched Sherpa to help creators write and plan long audio stories using custom AI models

The system uses proprietary tools trained on billions of hours of listener data to maintain story continuity

The company now has over 770,000 titles and doubled its annual revenue to $500 million

Pocket FM launched Sherpa, an AI platform designed for creating and planning long-form fiction content.
The tool aims to solve the difficulty of maintaining narrative consistency across hundreds of episodes in serial stories.
Sherpa utilizes a Narrative World Model that acts as a knowledge graph to track characters and plot points.
A Hierarchical Story Planner breaks down concepts into seasons, arcs, sequences, and individual scenes for structured writing.
The Prose Engine focuses on generating dialogue and managing emotional tension based on specific audience engagement signals.
Creators provide a brief concept which the system expands into detailed structures before drafting full episodes for review.
The platform integrates creator direction with AI assistance to ensure human control over key creative decisions.
Pocket Entertainment plans to use Sherpa to connect creation with distribution and enable global localization capabilities.

Generic large language models often struggle to keep track of complex details in very long serialized narratives.
Sherpa is built on proprietary models rather than single general-purpose AI to better handle these specific challenges.
The launch supports the parent company's goal of enabling a billion creators to produce content for a billion people.

Pocket FM operates a massive library containing more than 770,000 titles available to its users.
The platform hosts over 550,000 creators who produce audio content for the service.
It has recorded more than 5.5 billion hours of total playtime from its listener base.
Annualized content output grew significantly to approximately 2.6 million hours using the new Sherpa tools.
The company reported that its annual recurring revenue doubled to reach $500 million recently.
Top performing properties have generated over $100 million in revenue for the ecosystem.
Ten percent of eligible writers earn more than $200,000, with three becoming millionaires in under two years.

The company intends to expand cross-market capabilities through advanced localization features within the Sherpa platform.
