The ExMemo Tools plugin provides advanced document management and content optimization for Obsidian users. It utilizes large language models (LLMs) to generate and update file metadata, such as tags, descriptions, titles, and editing times. Users can optimize selected text within notes, move files to the most appropriate directories, and insert new content into the ideal position in existing documents. The plugin also offers smart file archiving, recommending suitable directories for files based on metadata and directory structure. Customizable prompts enable users to polish, translate, or restructure content directly in Obsidian. With features for automating repetitive metadata tasks and streamlining file organization, ExMemo Tools boosts productivity and efficiency for content management.
