Yes. With
Bring Your Own Key (BYOK), Neural Novelist writes using your own AI provider key: a code from the provider that lets the app use your account. The three-day trial gives you full app access with unlimited BYOK words, and the
$9/month BYOK plan continues it after the trial. For most writers the simplest choice is a Google Gemini key: sign in to
Google AI Studio, choose
Create API key, then paste the key into API Settings in Neural Novelist. Google, not Neural Novelist, sets that key's price, limits and data rules. Depending on your region, Google may use and human-review what you send on unpaid usage, so read
Google's Gemini API terms before using private work. You must be 18 or older to use the Gemini API. You can also use your own OpenAI, Anthropic or Z.ai key.
