FireQuill vs Narratomi

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.

Narratomi is a browser-based studio for writing and staging branching narrative games. Its editor places a live 3D stage alongside the script and choices, while a flow graph maps story routes and checks them as you write. Slash commands add choices, variables, and stage directions without code, and the compiler flags broken paths. Co-writers can work in the same scene live, and writers can create checkpoints, branch drafts, restore versions, and merge changes. Its AI staff writer drafts on its own branch, so writers can review, merge, rewind, or discard that work. Published stories open from a browser link without requiring a player account; anyone with the link can access them until they are unpublished. Writing, staging, and playing work in a modern desktop or phone browser without installation. User-created stories, scripts, and assets remain theirs. The free plan includes two projects, 50 monthly AI credits for mini models, 0.5 GB storage, and 1,000 monthly plays. Creator costs $12 per month billed annually and includes unlimited projects, 7,500 monthly AI credits, 5 GB storage, and 20,000 monthly plays.
