What is Sherpa?
Sherpa is a free AI story writing tool for fiction by Pocket FM. Many people have an idea for a story but no clear path from that spark to a finished draft. Sherpa walks you through that gap by helping you develop ideas, structure episodes, and write the prose itself.
It works through a conversational approach Pocket FM calls vibe writing. You describe your idea, and Sherpa asks questions, raises the stakes, and helps you build the story world before drafting begins. Once a draft is ready, you can convert it into an expressive AI audio drama and publish it directly to Pocket FM. The AI story writing tool is free to use and built for both first-time writers and experienced serialized fiction authors.

Real-World Applications
A first-time fiction writer with no publishing experience may find Sherpa the most accessible way to turn an idea into a finished, listenable story. The conversational drafting flow doesn’t require any formal storytelling knowledge. Someone who has always wanted to write a romance novel but never got past the first page can describe their premise, workshop it with Sherpa, and reach a complete episode without staring at a blank document.
Serialized fiction authors writing long-running shows with dozens of episodes can use Sherpa to keep their canon airtight. The Narrative World Model tracks every character goal, relationship shift, and plot thread across the archive, so a writer 60 episodes in can check what a character knew at episode 12 without rereading the whole series. It’s built for the exact kind of consistency problem that trips up long-form storytelling.
Audio drama creators who want their work on Pocket FM may find the production side of Sherpa cuts the gap between draft and published episode significantly. The AI audio drama generator assigns expressive, scene-appropriate narration to the finished text and maintains a consistent voice across the full run. Writers who work in one language but want a broader audience can also localize each episode into multiple languages without rebuilding the story from scratch.
Hobbyists writing fan fiction or genre fiction for personal projects might use Sherpa more loosely, as a sounding board for plot decisions or a way to get unstuck mid-episode. The feedback agent can flag pacing problems or inconsistencies before the story goes anywhere public, which is useful even if publishing is never the goal.
