The Zettelkasten LLM Tools plugin enhances note-taking in Obsidian by leveraging Large Language Models for advanced features like semantic search and automatic note improvement. The plugin allows users to generate embeddings for their notes, making it easy to find similar notes through semantic search. It also offers a copilot feature to help rewrite and improve notes by suggesting clearer titles, focused ideas, and relevant links. Additionally, users can batch generate embeddings for multiple notes based on customizable filename patterns. This tool helps streamline the Zettelkasten method by organizing and improving note connections using AI-powered insights.
