The AI Providers plugin acts as a centralized configuration tool for managing AI service settings within Obsidian. It allows users to store and share API keys and provider configurations across multiple AI-powered plugins, eliminating the need to enter the same credentials repeatedly. Supporting providers like Ollama, OpenAI, and OpenRouter-compatible APIs, the plugin simplifies the integration of AI tools in Obsidian. It is particularly useful for developers looking to streamline AI integration without handling provider-specific APIs manually.
