Key features: - AI entity extraction: reads your prose and proposes structured character profiles, location entries, and timeline events - Continuity checking: catches attribute conflicts, timeline contradictions, and dead characters reappearing - Worldbuilding dashboard: 12 categories with templates (fantasy, sci-fi, historical) - 8-format export: ePUB, PDF, DOCX, Final Draft, Markdown, HTML, RTF, Plain Text - 4 AI providers: OpenAI, Anthropic, Gemini, or local Ollama
Tech stack: SwiftUI, SwiftData, Cloudflare Workers (for the MAS proxy variant). The Direct variant sends AI requests directly to the provider using the user's own API keys — I never see their manuscripts.
The AI proposal system uses structured JSON schemas — the LLM returns typed proposals (character profile, timeline event, relationship, etc.) that the user can accept into their worldbuilding database. Not just free-text chat.
Two distribution channels: - Direct: $79 lifetime (BYOK + Ollama). Pre-sale from $39. - Mac App Store: Free + optional AI subscriptions through a Cloudflare Worker proxy.

Happy to talk about the architecture (structured AI proposals, multi- provider abstraction, StoreKit 2 integration, Cloudflare Worker proxy design) if anyone's interested.
