A Python library and local server that reverse engineers Microsoft Copilot's free web chat into an OpenAI-compatible REST API, giving access to GPT-4 and GPT-5 models without API keys or billing. It supports streaming, multi-turn conversations, and works as a drop-in replacement for the official OpenAI SDK.

Use cases

  • use gpt-4 for free without an openai api key
  • point existing openai sdk apps at a local free llm endpoint
  • build chatbots on top of microsoft copilot
  • stream llm responses in python
  • run a local openai-compatible api server
  • access copilot in regions where anonymous access is blocked

When to choose

  • you want free GPT-4/GPT-5 access using a Microsoft account instead of paid API billing
  • you already have OpenAI-compatible tooling and want a drop-in local endpoint
  • you need a Python library for streaming, multi-turn Copilot chats

When to avoid

  • you need a production-grade, officially supported API with SLAs
  • you cannot accept the risk of violating Microsoft's terms of service
  • you need models or features Copilot's web chat does not expose
