Start free. Upgrade when you’re serious.

Yes — NovelCanon is bring-your-own-key. You connect a key from OpenAI, Anthropic, Google, or OpenRouter and pay the provider directly at cost, with no markup from us. Prefer not to pay? Free models are available through OpenRouter. Your key is encrypted at rest and only ever decrypted in memory to make a request.

The latest frontier models from OpenAI, Anthropic, and Google — plus hundreds more (including free options) through OpenRouter. Because you bring your own key, you choose the model and can switch any time as new ones ship.

No — we never use your work to train AI. Requests go directly to the provider behind your own key, and the major providers don’t train on API traffic by default. If you reach third-party models through OpenRouter, we explicitly ask those providers not to retain or train on your data.

Three tiers. Instant in-editor micro-checks flag obvious slips as you type at zero AI cost. Per-scene analysis extracts and tracks the facts of your story. A full-manuscript deep scan cross-references everything to surface contradictions before your readers ever do.

Yes. Keep writing with no connection — your drafts are saved on your device and sync automatically when you’re back online. You can even install it on your desktop or phone like a native app. (AI features still need a connection.)

Absolutely. Import from DOCX, Markdown, plain text, EPUB, or a Scrivener project, and export finished work as DOCX, EPUB, or PDF.

Yes. Start free, no credit card required — the free plan includes 1 project, up to 3 chapters, and 20 AI actions per day. Upgrade to Pro for unlimited projects, the full Consistency Engine, voice matching, and all export formats.

Pro subscriptions are sold and processed securely by Polar, our Merchant of Record — so the charge on your card statement appears via Polar. You can cancel any time from your billing settings. Model usage from your own AI key is billed separately by your provider, at cost, with no markup from us.
