What it is

FireQuill is a web-based long-form writing system for novels, non-fiction, podcasts, documentaries, games, and musicals. It combines a story bible with generation that tracks characters, continuity, and voice. Its character engine follows characters’ voice, psychology, knowledge, relationships, and arc scene by scene, then proposes changes for the writer to accept or reject. Eight specialist validators cover developmental and line editing, plot, continuity, argument, evidence, counterargument, and audience fit; they flag issues rather than rewriting text. Non-fiction writers can upload PDFs, documents, and notes so chapters can draw on retrieved passages. Export options include Markdown, Word, EPUB, KDP-ready EPUB, print PDF, Fountain, Final Draft, and libretto formats. The free plan is free for two projects and has no AI. Companion costs $10 a month; Author is $20 a month; Studio is $30 a month. Audiobook and podcast narration are pay-as-you-go add-ons on any paid plan. FireQuill says it does not sell user content or train public models on it, but sends relevant writing to AI providers when users request generation or checks.
