Different tools for different needs.
StoryBook takes a local-first, open-source approach. Other tools may offer different workflows, cloud services or subscription models. Compare the trade-offs and choose what fits your way of writing.
A writing environment for long-form fiction, with AI running on your own computer. Plan your story, develop your world, write with AI and keep track of canon.

|---|---|---|---|---|
| Writing | ||||

| Planning & world | ||||
| Development methods | Snowflake, Three-act, Save the Cat and Hero’s Journey — or no method | Flexible planning structures and beat-based workflows | Story-planning and beat-development tools | Templates, outliner and corkboard; structure is largely user-defined |
| Planning tools | Brainstorm, synopsis, briefs, scenes and Timeline — comparing manuscript order with story chronology and tracking plot threads | Planning, Codex and scene/story organization tools | Planning and story-development tools built around fiction workflows | Outliner, corkboard, labels, metadata and project documents |

| Character / world exploration | Character interviews and exploratory AI conversations; nothing becomes canon automatically | Character and world context can be developed through Codex and AI workflows | Character and worldbuilding assistance | Manual character sheets, notes and research documents |
| Workflow | ||||
| Import | Lore import + JSON backup restore. Lore can be extracted and reviewed before becoming canon. There is currently no direct manuscript importer from other writing tools; existing prose can be pasted into a chapter. | Import options for manuscript and planning material | Import existing writing into projects | Broad document and project import options |
| Publish & export formats | PDF, ePub, HTML, ODT, RTF, Markdown and TXT | Export options for manuscript workflows | Document export for continued editing and publishing workflows | Strong compile/export system including common manuscript and ebook formats |

| AI setup | Local model endpoint you configure; separate Writing and Review models supported | Provider integrations, with model choice depending on configured services | Hosted AI supplied by the service | No built-in generative AI model setup |
| Privacy / local storage | Manuscript, Story Bible and app data stay local; no telemetry or cloud sync from StoryBook | Hosted app; privacy depends on platform and connected AI providers | Hosted service; writing and AI workflows use cloud infrastructure | Projects are primarily local files, with optional external sync workflows |
