Advanced Paste is a module in Microsoft's open-source PowerToys suite for Windows that reformats clipboard content into Markdown, JSON or a custom prompt result using an AI provider you configure yourself. In settings you add a model provider and, per Microsoft's documentation, usually supply the API key, endpoint URL and any extra options for OpenAI, Azure OpenAI, Mistral or Google, or point at a local Foundry Local or Ollama model requiring no key at all. PowerToys is MIT licensed and free; you pay only your chosen provider. 137,669 stars on the monorepo, continuous development.
