Anthropic Setup

Set up Anthropic (Claude) as your AI provider in Continuum Writer.

Get an API Key

  1. Go to console.anthropic.com
  2. Sign in or create an account
  3. Navigate to API Keys
  4. Click "Create Key"
  5. Copy the key
You'll need to add credit to your Anthropic account before API calls will work. This is separate from a Claude Pro subscription.

Configure in Continuum Writer

On first launch

  1. Choose Anthropic as your AI provider in the setup wizard
  2. Paste your API key
  3. Click "Save & Test Connection" — the app will detect available models
  4. The app will select recommended default models automatically
  5. Click Next to continue

From the settings menu

  1. Open Settings (gear icon, bottom-left)
  2. Under AI Provider, select Anthropic
  3. Paste your API key
  4. The app will select recommended default models automatically
  5. Click "Test Connection" to verify

Recommended Models

The app uses three model roles (Chat, Router, and Summarise). For Anthropic, a good starting point is:

  • Chat: Claude Sonnet (latest version) — excellent for creative writing
  • Router / Summarise: Claude Haiku (latest version) — fast and affordable

Anthropic releases new model versions regularly — check their model page for the latest options. See Recommended Models for more detail on what each role needs.

Typical Costs

Most writers spend £2-5/month with moderate AI usage. Costs depend on how often you use the chat and how long your conversations are.
Anthropic's Claude models are particularly good at creative and nuanced writing tasks.
