 | Value    | Description                                                    | Use case                                    |
 | -------- | -------------------------------------------------------------- | ------------------------------------------- |
 | `openai` | Default — calls ChatGPT via OpenAI API                       | Automated second-opinion queries            |
 | `manual` | Copy-paste — wraps prompts in a ready-to-copy format         | Manual ChatGPT Web/Business as advisor      |
+| `ollama` | Local AI — uses Ollama `/api/chat` with Qwen3 model          | Offline/local second-opinion via local LLM  |
 
 For the **manual** provider, set `CHATGPT_MCP_PROVIDER=manual`. Each tool call returns a copy-ready prompt block you can paste into ChatGPT Web or ChatGPT Business. This turns Claude Code into an orchestrator: it builds the perfect prompt and formats it for you to hand off to ChatGPT as a second-opinion advisor — all without API calls, quotas, or cost.
 
-The factory pattern enables future providers (Ollama, Anthropic, custom) without touching tool handlers.
+For the **ollama** provider, set `CHATGPT_MCP_PROVIDER=ollama` and ensure Ollama is running locally. The provider uses Qwen3 via Ollama's OpenAI-compatible `/api/chat` endpoint with no additional dependencies. This turns Claude Code into an orchestrator: it builds the perfect prompt and sends it directly to your local model — all without cloud API calls, quotas, or cost.
