Summary

FireQuill is a web-based long-form writing system for books, podcasts, and other creative projects. Its story bible and character engine track characters’ voice, psychology, knowledge, relationships, and development across scenes, then suggest updates for the writer to accept or reject. Eight specialist validators check areas including plot, continuity, evidence, and audience fit; they flag concerns rather than rewriting prose. Writers can choose workflows for fiction, non-fiction, podcasts, documentaries, games, and musicals. For non-fiction, uploaded PDFs, documents, and notes can supply passages for chapter drafting. Export options include Markdown, Word, EPUB, KDP-ready EPUB, print PDF, Fountain, Final Draft, and libretto formats. FireQuill says it does not sell user content or use it to train public models, but relevant writing is sent to AI providers when users request generation or checks. The free plan allows two projects without AI. Paid plans start at $10 per month, and paid plans can add audiobook and podcast narration on a pay-as-you-go basis.
