Private Writing Studio

A local-first, AI-free full writing toolkit for novelists and long-form authors

Problem

Writers need a timeline editor, character sheets, EPUB export, cover design and more, but regular text editors lack these; they also want something private, not cloud-dependent, and free of AI involvement. One developer built exactly this—local-first, open-source, AI-free authoring software—showing a real unmet need.

Solution

A local-first writing app with built-in timeline, character cards, worldbuilding notes, chapter management, EPUB/PDF export with simple cover templates. All data stays local, optionally encrypted, no AI by default, and exportable to Markdown/JSON to avoid lock-in.

Users

Novelists, screenwriters, long-form writers, privacy-conscious users who don't want AI in their creative process

MVP

Timeline view with drag-to-order events; character cards and relationship maps; chapter outline with word counts; EPUB export; local folder storage with optional encryption

Revenue

One-time purchase or open-core with paid extras (premium export templates, cover designer, paid multi-device sync); sponsorship license

Why now

Mainstream writing tools either go cloud-subscription or shove AI features in, making privacy and predictability scarce selling points; local-first stacks (SQLite, Tauri) are mature enough for a solo dev to ship in weeks
