Written By Daniel Nguyen
Add your Anthropic API key to chat with Claude models in BoltAI. You also get Anthropic's own tools for web search and running code.
Before you start
- An Anthropic API account with credits.
- An API key. Create one at Anthropic API keys.
Set up Anthropic in BoltAI
- Open Settings › AI Providers, click + and choose Anthropic.
- Paste your key into API Key. Leave Base URL empty.
- Click Next.
- Keep all models, or untick the ones you don't want. To choose this provider's default model, hover over it and click Set as Default.
- Click Add Service.

Start a chat with Claude models
Click the model name in the message box, press ⇧ ⌘ M, or type /model. Pick a model under Anthropic.
To start every new chat with it, right-click the model and choose Set Provider & Model as Default. See Choose and switch models.

Use Anthropic's built-in tools
In the chat's Tools menu (⇧ ⌘ T), turn on what you need under Provider Tools:
- Web Search, for anything recent.
- Code Execution, to run code.
See Tools in a chat.
If it doesn't connect
- BoltAI couldn't verify this API key: copy the key again in full. If you just created it, wait a few minutes and try again.
- Setup works, but replies fail: the account may be out of credits. Check your billing in your Anthropic account.
- A model is missing: on the provider's page, click Refresh Model List.
- On the provider's page, open the ⋯ menu and choose Test Connection.
