FireQuill is a web-based writing system for long-form projects such as novels, nonfiction, podcasts, documentaries, games, and musicals. It combines a story bible, generation, and specialist editorial checks that track character details, continuity, and voice. Its character engine follows traits such as psychology, knowledge, relationships, and arc across scenes, then proposes changes for the writer to accept or reject. Eight validators assess areas including developmental and line editing, plot, continuity, argument, evidence, counterargument, and audience fit; they flag issues rather than correcting prose automatically. For nonfiction, 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. FireQuill says it does not sell user content or use it to train public models, but relevant writing goes to AI providers when users request generation or checks. The free plan allows two projects with no AI. Paid plans start at $10/mo, and audiobook and podcast narration are pay-as-you-go add-ons on paid plans.
