Configuration

Chatter stores its configuration on disk so you can reuse API keys, default providers, and Ollama settings. Configuration lives in platform-specific directories:

• macOS: ~/Library/Application Support/chatter/config.json
• Linux: ~/.config/chatter/config.json
• Windows: %APPDATA%\chatter\config.json

Managing API Keys

Set a Gemini API key once and Chatter will reuse it for future sessions:

chatter config set-api-key

Alternatively, export the GEMINI_API_KEY environment variable before starting the CLI. Chatter currently stores the API key directly in the plaintext JSON configuration file, so treat config.json as sensitive and manage file permissions accordingly.

Provider Defaults

Configuration fields worth knowing:

• provider — active provider ("gemini" or "ollama")
• default_model — fallback model when you omit --model
• ollama.endpoint — base URL for the Ollama server (defaults to http://localhost:11434)

Edit these values through the CLI or by modifying the JSON file directly.
