Anthropic (maker of Claude) is one of seven additional providers unlocked on a paid plan, connected the same simple way as every other provider in SynaPost.
1. Get an API key
Create or sign in to an account at console.anthropic.com and generate an API key from the console.
2. Connect it in SynaPost
- Go to Settings → AI & Images and click Configure on the Anthropic card.
- Paste your key and click Test connection – SynaPost verifies the key works before letting you save it.
- Enter the exact model ID you want to use (for example a current Claude model ID from Anthropic’s own documentation), and optionally set Anthropic as your default provider.
- Save. The card now shows as Connected.
Billing
SynaPost never meters or marks up usage – you’re billed directly by Anthropic at your own account’s rates, separate from your SynaPost subscription.
Switching later
You can change the model ID or switch to a different provider entirely at any time by reconfiguring – nothing about your topics, drafts, or history depends on which provider generated them. See Choosing an AI Provider for the full list of what’s available on your plan.
