The Smart Second Brain plugin enhances knowledge management in Obsidian by integrating AI-powered assistance to interact with notes. It enables users to chat with their notes using a retrieval-augmented generation (RAG) pipeline, offering references to original sources within the vault. The plugin supports various large language models, including local models via Ollama and cloud-based models like ChatGPT. Users can switch between models based on their needs and preferences. The plugin operates offline to ensure privacy and provides options to save and resume chat sessions.

The BMO Chatbot plugin brings AI-powered interaction to Obsidian, enabling users to brainstorm and generate ideas while creating notes. It supports multiple Large Language Models (LLMs) from providers like OpenAI, Anthropic, and self-hosted APIs like Ollama and LM Studio. The plugin offers customizable profiles for chatbots, which can have unique knowledge, personalities, and presets. Users can chat with the bot in real-time, integrate it with current notes, and save conversations in markdown format for further analysis. Additional features include markdown-rendered responses, commands for configuring prompts and models, and the ability to edit memory states during conversations.

The brAIn plugin integrates a ChatGPT-powered chatbot with Obsidian, enabling users to ask questions and receive answers based on their vault's notes.

Users can index their notes for chatbot access and update the index as needed. By default, embeddings are generated locally for privacy, but OpenAI embeddings can be enabled for efficiency. The plugin supports Docker for its backend and offers robust privacy guarantees, ensuring that user data is handled securely. This tool is designed for knowledge management and quick access to insights from your notes.
