How billing works: API usage is pay-as-you-go, separate from any Claude.ai subscription. You add credits to your Anthropic account and each AI request costs a small amount. Haiku requests cost fractions of a cent; Sonnet and Opus cost more but are more capable.
Your key is stored only in your browser's local storage. It never leaves your machine except to authenticate with Anthropic's servers.

Writing Voice
Paste a sample of your writing (300–2,000 words) and the AI will learn your voice — your sentence rhythm, tone, vocabulary, and style — then use it to guide every response.
