The Metadata Auto Classifier plugin for Obsidian simplifies the process of tagging and structuring notes by automatically generating relevant metadata based on content. Users can leverage intelligent tag suggestions to quickly categorize information, and set up custom frontmatter fields that populate automatically, creating a well-organized and enriched dataset in their vault. With built-in commands accessible through Obsidian's command palette, users can fetch specific tags or frontmatter details on-demand, saving time and effort in note organization. Additionally, OpenAI’s GPT models power the metadata generation, making tag and frontmatter suggestions highly accurate and relevant to each note’s content. This tool is ideal for users who want to maintain organized, metadata-rich notes without manual input.
