The AI Research Assistant plugin integrates advanced tools for prompt engineering and AI model interactions within Obsidian. It allows users to manage conversations with AI models like OpenAI's ChatGPT, save them as searchable notes, and organize them using Obsidian's tagging and linking features. The plugin provides real-time memory management, enabling users to prioritize or exclude specific conversation messages as context. It supports live editing of preambles, prompts, and context, and offers the ability to swap models mid-conversation to compare outputs. Additionally, users can view raw API inputs and outputs for a detailed analysis of AI responses.
