The AI Note Tagger plugin streamlines the process of organizing notes in Obsidian by leveraging Claude AI to generate context-aware tags. It scans the content of your notes and suggests relevant tags, which are automatically added to the frontmatter. Users can choose to tag a single note or apply batch tagging across their entire vault. The plugin offers customization options, such as limiting the number of tags per note and modifying the AI prompt to better suit individual workflows. It supports multiple Claude models and provides a straightforward interface for managing the tagging process.
