AI Writing AssistantFiction Genie
Fiction Genie wanted an AI co-writing feature that felt like a collaborator, not a slot machine you pull for random paragraphs.
Challenge
An early generic-LLM integration produced generic, out-of-voice text that writers had to heavily rewrite, and there was no way to steer tone or keep continuity across a long draft.
Solution
We built a retrieval-grounded generation pipeline that references a writer's own prior chapters and style notes, with confidence-scored suggestions writers can accept, edit, or discard inline.

“Our first version of AI assist felt like generic autocomplete that ignored everything the writer had already built. This version actually remembers a character's voice three chapters back — that's the difference between a gimmick and a real tool.”
