NovelCrafter is a bring-your-own-key (BYOK) AI writing environment built around the **Codex** — a structured story bible covering characters, locations, lore, and items that automatically feeds context into every AI prompt. Authors connect their own OpenAI, Anthropic, or OpenRouter API keys, paying token costs separately from the subscription.

## What You Get

- **Codex story bible:** Structured entries for every named character, place, and concept; the system injects only relevant Codex entries into each scene's prompt to keep context windows tight.
- **Scene-by-scene workspace:** Plan beats, write scenes, and review revisions in a single editor with chapter and act organization.
- **Bring your own key:** Connect OpenAI, Anthropic Claude, or OpenRouter (any model) — pay token costs at provider rates, not marked-up "AI words."
- **Outline tools:** Plot grid, beat breakdowns, and scene cards with drag-to-reorder.
- **Revision history:** Track scene-by-scene edits with rollback.

## Pricing

- **Hobby:** $4/mo or $40/yr (limited features, single project)
- **Solo:** $10/mo or $100/yr (full features, unlimited projects)
- **Scribe:** $20/mo or $200/yr (priority support, advanced features)
- **AI usage is separate** — you pay your model provider directly. Realistic monthly token spend ranges from $5 (hobbyist) to $50+ (heavy daily writers).

## Strengths

- **No "AI word" caps:** Pay actual API costs instead of marked-up tokenized credits — typically cheaper at high volume than Sudowrite.
- **Codex is best-in-class:** The structured worldbuilding system keeps long-series continuity better than free-text "lorebooks" in competitors.
- **Model freedom:** Switch between Claude Opus for prose, GPT-4o for plotting, and budget models for chunky generation — Sudowrite locks you to its house model.

## Limitations

- **BYOK setup friction:** Non-technical authors find the API key setup intimidating; expect 30-60 minutes of first-time configuration.
- **Costs are split:** Subscription + API costs make budget planning harder than a flat-fee tool.
- **Web-only:** No desktop or mobile apps.
- **Smaller community than Sudowrite:** Fewer learning resources, smaller Discord — most workflow knowledge is in YouTube tutorials.
